    Mediastinal cysts are a group of benign mediastinal lesions, and their diagnoses are primarily depended on x-ray and computed tomography. The development of ultrasound instruments and inspection techniques in recent years has led to the ability to use transthoracic echocardiography to clearly display structures surrounding the heart according to the dark fluid space (blood) of the atrium, ventricles, and large vessels as an acoustic window. This technique offers improved detection rates of mediastinal lesions. We report a case of a mediastinal cyst that was first detected and diagnosed on thoracic echocardiography examination and then confirmed by thoracoscopic surgery and pathological analysis.

    Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become a minimally invasive tool with excellent diagnostic accuracy and low risk of complications in the diagnosis of thoracic diseases, including lung cancers and primary mediastinal lesions. Occasionally, EBUS-TBNA may be useful in identifying thoracic metastasis from distant tumors. Here we report an interesting and rare case of mediastinal metastasis of ovarian carcinoma diagnosed by EBUS-TBNA. PMID:26623131

    Objective: We presented a rare case of recurrent hepatocellular carcinoma after liver transplant manifested as an isolated mediastinal mass. Methods: A 62-year-old man was referred for evaluation of atypical chest pain and abnormal finding of a computed tomography of the chest. He had history of chronic hepatitis C liver cirrhosis and hepatocellular carcinoma underwent orthotopic liver transplant as a curative treatment three years earlier. Results: The computed tomography of the chest demonstrated paratracheal mediastinal lymphadenopathy. He subsequently underwent endobronchial ultrasound with transbronchial needle aspiration (EBUS-TBNA). The right paratracheal lymph node station 4R was sampled. Rapid on-site cytology evaluation demonstrated recurrent metastatic hepatocellular carcinoma. Conclusion: Pulmonologist should be cognizant of diagnostic utility of EBUS-TBNA in this clinical setting as more transplant patients on immunosuppressive medications with enlarged mediastinal lymphadenopathy of unknown origin will be referred for further evaluation.

    The diagnostic strategy for asymptomatic patients with persistent bilateral bilar adenopathy often involves invasive procedures. The authors used Bayesian analysis to: (1) estimate the relative prevalences of diseases causing bilateral bilar adenopathy; (2) assess changes in the prevalence of disease by race, the presence of other clinical symptoms, and geography; and (3) determine the value of relevant noninvasive tests, including the angiotensin-converting enzyme (ACE) assay, gallium scan, and purified protein derivative (PPD), in order to assess when a strategy of watchful waiting is appropriate. The analysis indicated that the ACE assay, particularly when paired with the PPD, can identify many patients who might safely be managed without immediate invasive biopsy. Patients who are ACE+ and PPD- have an estimated probability of sarcoidosis of 0.95 or greater; patients who are ACE- and PPD+ have a probability of tuberculosis of 0.86 if black, 0.79 if white. In contrast, gallium scanning has no diagnostic role in this clinical situation. Bronchoscopic or mediastinoscopic biopsy has a limited role for patients who are ACE+ PPD- or ACE- PPD+ because of limited sensitivity. Patients who are both ACE- and PPD-, particularly if white, may have a high enough risk of lymphoma to consider invasive biopsy.

    AIM: Rapid on-site evaluation (ROSE) is used widely during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). BIOEVALUATOR® is a device used for determining whether the tissues obtained by EBUS-TBNA are appropriate for a pathological diagnosis. This study describes our experience with ROSE using BIOEVALUATOR® during EBUS-TBNA for diagnosing pulmonary and mediastinal diseases. MATERIALS AND METHODS: We retrospectively evaluated the results of 35 patients who underwent EBUS-TBNA with BIOEVALUATOR® between December 2011 and February 2013. For the diagnosis, the tissue areas were appearing white and red through BIOEVALUATOR® are considered to be appropriate and inappropriate, respectively. We examined their medical records to obtain information concerning the examination of BIOEVALUATOR® results of the patient's materials (white/red), the diagnosis yield, site and size of lymph nodes and number of needle passes. RESULTS: The median longest diameter of 40 lymph nodes (21 #7, 13 #4R, 4 #4L and 2 #11) from 35 patients was 27.9 (range 12.4-50.6) mm and the median number of needle passes was 2 (range 1-5). The definitive diagnosis was made by EBUS-TBNA in 28 of 35 patients, by thoracotomy in one patient and BIOEVALUATOR® results were white and lymphocytes were seen in the rest six patients. The BIOEVALUATOR® results of other patients without accurate diagnosis were left indefinitive. Finally, the six patients were judged as having benign lymphadenopathy because the lymph node size on computed tomography decreased or remained stable after for at least 8 months. CONCLUSIONS: Checking aspirated samples using BIOEVALUATOR® appears useful for determining their adequacy for pathological diagnosis. PMID:24551012

    Leiomyosarcomas are extremely rare tumors which develop from smooth muscle, usually in the esophagus and large vessels (inferior vena cava, pulmonary artery, and superior vena cava). In very rare cases, leiomyosarcomas develop from small vessels in the soft tissue of the mediastinum. Clinical expression of mediastinal leiomyosarcomas (dysphagia, dysphonia) is related to their large size and the subsequent compression of mediastinal structures. At pathology examination, the gross aspect is one of a single cell tumor. Microscopically, the tumor may be highly undifferentiated making it necessary to use specific immune markers (actin and desmin) or ultra-structural analysis to establish the diagnosis. Treatment of localized tumors is based on surgical excision, either alone or in combination with radiotherapy of the mediastinum. Chemotherapy, generally dexorubicin, is indicated in case of metastatic dissemination, but outcome remains uncertain. As for all soft tissue sarcomas, the prognosis of mediastinal leiomyosarcoma depends on the size of the tumor, its histological structure and its resectability. PMID:10339766

    Among 29,875 autopsies 59 cases of mediastinal echinococcosis were revealed. Among 4178 patients with thoracic echinococcosis 55 patients had mediastinal echinococcosis. All the patients were operated, most of them underwent ideal ecinococcectomy. Intraoperative prophylaxis of echinococcosis was performed: plearal cavity was treated by low-frequency ultrasound and glycerin. 7 examined patients demonstrated reduction of immune and phagocytosis indices in blood (DC3+, CD4+, CD8+, CD16+, CD21+). Increase of immunoglobulines A, M, G and circulating immune complexes was revealed. Reactions of scolexprecipitation and lymphocytes antigen-fixing were positive. PMID:11875945

    Background: Tubercular lymphadenitis is the commonest extra pulmonary manifestation in cervical and mediastinal locations. Normal characteristics of lymph nodes (LN) have been described on ultrasonography as well as by Endoscopic Ultrasound. Many ultrasonic features have been described for evaluation of mediastinal lymph nodes. The inter and intraobserver agreement of the endosonographic features have not been uniformly established. Methods and Results: A total of 266 patients underwent endoscopic ultrasound guided fine needle aspiration and 134 cases were diagnosed as mediastinal tuberculosis. The endoscopic ultrasound location and features of these lymph nodes are described. Conclusion: Our series demonstrates the utility of endoscopic ultrasound guided fine needle aspiration as the investigation of choice for diagnosis of mediastinal tuberculosis and also describes various endoscopic ultrasound features of such nodes.

    1987-05-01

    Upper airway obstruction in primary or recurrent carcinomas of the head and neck extending into the mediastinum may demand surgical intervention despite severe technical difficulties in patients with tumors previously considered inoperable. In fact, many of these tumors may be operable and some perhaps curable. A technique has been developed based in part on our experience with previously described procedures. A preliminary sternal split is used to demonstrate the extent of the mediastinal involvement as well as to provide enhanced exposure and proximal control of the great vessels. The pectoralis major muscle is used with a generous flap of overlying skin comprising nearly half of the anterior portion of the chest. A tracheostomy is then created in a fashion similar to the placement of a cardiac valvular prosthesis by creating a circular defect in the pectoralis major flap and suturing it to the tracheal remnant. This technique offers a reasonably safe and reliable means of creating a low anterior mediastinal tracheostomy for tumors previously considered inoperable. The preliminary sternal split makes the procedure safer and easier to perform, and the use of a very large pectoralis major island flap allows for reliable closure of the resulting mediastinal and sternal defects.

    Spontaneous mediastinal emphysema, also known as spontaneous pneumomediastinum, is defined as radiologically detected free air in the mediastinum, without preceding trauma. It is a rare condition, mainly affecting young adults. It can be caused by coughing, strenuous sports or cocaine inhalation, however, 40% are idiopatic. Common symptoms are chest pain and dyspnoea. 75-90% can be diagnosed with a chest X-ray, and 100% with a computed tomography. Treatment is symptomatic and complications are rare, however, pneumothorax and pneumorrachis have been reported. PMID:26750190

    BACKGROUND: The use of computed tomography in mediastinal staging of lung cancer relies on the premiss that malignant lymph nodes are larger than benign ones. This hypothesis was tested by linking node size and presence or absence of malignancy and looking at factors possibly influencing the size of benign nodes. METHODS: All accessible mediastinal lymph nodes were taken from 56 consecutive patients with lung cancer who underwent thoracotomy. Nodes were measured and histologically examined. Resected cancer bearing lung from 44 of these patients was assessed for degree of acute and chronic inflammation. RESULTS: Lymph node size was not significantly related to the presence of metastatic disease, 58% of malignant and 43% of benign lymph nodes measuring over 15 mm. Similarly, there was no statistically significant relation between size of lymph nodes and the likelihood of malignancy, 20% of lymph nodes of 10 mm or more but also 15% of those less than 10 mm being malignant. Thresholds of 15 and 20 mm showed similar results. The maximum size of benign lymph nodes was significantly greater in those patients with histological evidence of acute pulmonary inflammation than in those without. CONCLUSIONS: The study shows that in patients with lung cancer (1) malignant mediastinal lymph nodes are not larger than benign nodes; (2) small mediastinal lymph nodes are not infrequently malignant; and (3) benign adenopathy is more common in patients with acute pulmonary inflammation.

    Abstract Fibrosing mediastinitis is caused by a proliferation of fibrous tissue in the mediastinum with encasement of mediastinal viscera and compression of mediastinal bronchovascular structures. Pulmonary hypertension (PH) is a severe complication of fibrosing mediastinitis caused by extrinsic compression of the pulmonary arteries and/or veins. We have conducted a retrospective observational study reviewing clinical, functional, hemodynamic, radiological characteristics, and outcome of 27 consecutive cases of PH associated with fibrosing mediastinitis diagnosed between 2003 and 2014 at the French Referral Centre for PH. Fourteen men and 13 women with a median age of 60 years (range 18–84) had PH confirmed on right heart catheterization. The causes of fibrosing mediastinitis were sarcoidosis (n = 13), tuberculosis-infection confirmed or suspected (n = 9), mediastinal irradiation (n = 2), and idiopathic (n = 3). Sixteen patients (59%) were in NYHA functional class III and IV. Right heart catheterization confirmed moderate to severe PH with a median mean pulmonary artery pressure of 42 mm Hg (range 27–90) and a median cardiac index of 2.8 L/min/m2 (range 1.6–4.3). Precapillary PH was found in 22 patients, postcapillary PH in 2, and combined postcapillary and precapillary PH in 3. Severe extrinsic compression of pulmonary arteries (>60% reduction in diameter) was evidenced in 2, 8, and 12 patients at the main, lobar, or segmental levels, respectively. Fourteen patients had at least one severe pulmonary venous compression with associated pleural effusion in 6 of them. PAH therapy was initiated in 7 patients and corticosteroid therapy (0.5–1 mg/kg/day) was initiated in 3 patients with sarcoidosis, with 9 other being already on low-dose corticosteroids. At 1-year follow-up, 3 patients had died and among the 21 patients evaluated, 3 deteriorated, 14 were stable, and only 4 patients with sarcoidosis improved (4 receiving corticosteroids and 1

    The mediastinum is among the most frequent anatomic region in which germ cell tumors (GCT) arise, second only to the gonads. Mediastinal GCT (mGCT) account for 16 % of all mediastinal neoplasms. Although the morphology and (according to all available data) the molecular genetics of mediastinal and gonadal GCT are identical, a number of unique aspects exist. There is a highly relevant bi-modal age distribution. In pre-pubertal children of both sexes, mGCT consist exclusively of teratomas and yolk sac tumors. The prognosis is generally favorable with modern treatment. In post-pubertal adults, virtually all patients with malignant mGCT are males; the prognosis is more guarded and depends (among other factors) on the histological GCT components and is similar to GCT in other organs. So-called somatic type malignancies (i. e. clonally related, non-germ cell neoplasias arising in a GCT) are much more frequent in mGCT than in other organs, and the association between mediastinal yolk sac tumors and hematological malignancies, such as myelodysplasias and leukemias, is unique to mediastinal tumors. The prognosis of GCT with somatic type malignancies is generally dismal. PMID:27491549

    We report a case of inadvertent hoarseness after surgery for primary pulmonary amyloidosis. A 55-year-old male was transferred to our facility due to a lung mass. Chest computed tomography revealed a solitary pulmonary nodule. Positron emission tomography–computed tomography showed fluorodeoxyglucose uptake in the main mass and in the mediastinal lymph nodes. To confirm the pathology of the mass, wedge resection and thorough lymph node dissection were performed via video-assisted thoracic surgery (VATS). No complications except for hoarseness were observed; hoarseness developed soon after surgery and lasted for 3 months. The main mass was diagnosed as amyloidosis, but this was not found in the lymph nodes. In conclusion, VATS wedge resection for peripheral amyloidosis is a feasible and safe procedure. However, mediastinal lymph node dissection is not recommended unless there is evidence of a clear benefit. PMID:27298804

    A 35-year-old Japanese man's routine chest radiography revealed an abnormal opacity. Chest computed tomography and magnetic resonance imaging showed a 5.5 cm in dia. cystic tumor located at the left anterior mediastinum. The tumor was suspected to be an asymptomatic thymic cyst, and we chose observation for the tumor. At the 3-year follow up, the cystic tumor had gradually enlarged to 7.5 cm in dia. and we thus performed a surgical resection via left video-assisted thoracic surgery. An immunohistochemical analysis showed that the cystic tumor was not a thymic cyst but rather a mediastinal cystic lymphangioma. Mediastinal cystic lymphangiomas are very rare, and they are difficult to diagnose preoperatively. Complete surgical resection is proposed for the treatment of such tumors. PMID:26690247

    Malignancy complicating pregnancy represents one of the most challenging clinical situations. Lack of evidence and the presence of the dependent fetus contribute to the management dilemma. A 26-year-old primigravida presented at 23 weeks of gestation with a bulging substernal mass. Fine-needle aspiration was reported as mediastinal dysgerminoma. She was treated with weekly bleomycin and three weekly cisplatin and etoposide (BEP). Maternal neutropenia after 11 weeks of bleomycin required colony stimulator factor. Fetal growth restriction necessitated delivery at 31 weeks. Significant clinical and radiological tumour regression was noted after chemotherapy. Postnatally mother received external beam radiotherapy but the disease worsened two weeks after the completion of radiotherapy. Mediastinal dysgerminoma differs from the ovarian counterpart and therefore therapeutic success reports on ovarian germ cell tumours complicating pregnancy cannot be extrapolated. The safety of the BEP regimen for the fetus is yet to be established.

    Mediastinal tumors are relatively uncommon, usually incidentally discovered on a chest X-ray in asymptomatic patients. Young adults are particularly concerned. Mediastinal masses represent a group of heterogeneous histological type cell. A definite diagnosis is essential leading to an adequate prompt therapeutic strategy when either benign disease or aggressive malignant tumor is conceivable. Indeed the therapeutic management of such tumors could be strictly medical, requiring exclusive surgical approach or includes a multimodal treatment. Clinical examination and imaging are important tools in the diagnostic approach. However the specific diagnosis could be complex and requires histological confirmation by an experienced pathologist after examination of large biopsies of the tumor. Several investigations, including surgical invasive exploration, should be quickly requested in order to achieve a final diagnosis and refer patients in an adequate therapeutic scheme without delay. The aim of this article is to point out the available diagnostic tools in mediastinal masses, including surgical approach, and to identify the role of surgical resection in specific subtypes.

    Primary mediastinal Classical Hodgkin lymphoma (CHL) is rare. Nodular sclerosis CHL (NS-CHL) is the most common subtype involving the anterior mediastinum and/or mediastinal lymph nodes. Primary thymic CHL is exceedingly rare. The disease typically affects young women and is asymptomatic in 30% to 50% of patients. Common symptoms include fatigue, chest pain, dyspnea and cough, but vary depending on the location and size of the tumor. B-symptoms develop in 30% of cases. By imaging, primary mediastinal CHL presents as mediastinal widening/mediastinal mass that does not invade adjacent organs but may compress vital structures as bulky disease. Histopathology is the gold standard for diagnosis. Primary mediastinal NS-CHL consists of nodules of polymorphous inflammatory cells surrounded by broad fibrous bands extending from a thickened lymph node capsule. The cellular nodules contain variable numbers of large Hodgkin/Reed-Sternberg cells, required for diagnosis. Primary thymic CHL may exhibit prominent cystic changes. The histopathologic recognition of NS-CHL can be challenging in cases with prominent fibrosis, scant cellularity, artifactual cell distortion, or an exuberant granulomatous reaction. The differential diagnosis includes primary mediastinal non-HLs, mediastinal germ cell tumors, thymoma, and metastatic carcinoma or melanoma to the mediastinum. Distinction from primary mediastinal non-HLs is crucial for adequate therapeutic decisions. Approximately 95% of patients with primary mediastinal CHL will be alive and free of disease at 10 years after treatment with short courses of combined chemoradiotherapy. In this review, we discuss the history, classification, epidemiology, clinicoradiologic features, histopathology, immunohistochemistry, differential diagnosis, and treatment of primary mediastinal CHL.

    Nine dogs were diagnosed with cranial mediastinal carcinomas. Based on histological and immunohistochemical analysis, four dogs were diagnosed with ectopic follicular cell thyroid carcinomas, one dog with ectopic medullary cell thyroid carcinoma, two dogs with neuroendocrine carcinomas and two dogs with anaplastic carcinomas. Clinical signs and physical examination findings were associated with a space-occupying mass, although one dog was diagnosed with functional hyperthyroidism. Surgical resection was attempted in eight dogs. The cranial mediastinal mass was invasive either into the heart or into the cranial vena cava in three dogs. Resection was complete in six dogs and unresectable in two dogs. All dogs survived surgery, but four dogs developed pulmonary thromboembolism and two dogs died of respiratory complications postoperatively. Adjunctive therapies included pre-operative radiation therapy (n=1) and postoperative chemotherapy (n=3). Three dogs had metastasis at the time of diagnosis, but none developed metastasis following surgery. The overall median survival time was 243 days. Local invasion, pleural effusion and metastasis did not have a negative impact on survival time in this small case series. PMID:19178660

    In the past, mediastinal surgery was associated with the necessity of a maximum exposure, which was accomplished through various approaches. In the early 1990s, many surgical fields, including thoracic surgery, observed the development of minimally invasive techniques. These included video-assisted thoracic surgery (VATS), which confers clear advantages over an open approach, such as less trauma, short hospital stay, increased cosmetic results and preservation of lung function. However, VATS is associated with several disadvantages. For this reason, it is not routinely performed for resection of mediastinal mass lesions, especially those located in the anterior mediastinum, a tiny and remote space that contains vital structures at risk of injury. Robotic systems can overcome the limits of VATS, offering three-dimensional (3D) vision and wristed instrumentations, and are being increasingly used. With regards to thymectomy for myasthenia gravis (MG), unilateral and bilateral VATS approaches have demonstrated good long-term neurologic results with low complication rates. Nevertheless, some authors still advocate the necessity of maximum exposure, especially when considering the distribution of normal and ectopic thymic tissue. In recent studies, the robotic approach has shown to provide similar neurological outcomes when compared to transsternal and VATS approaches, and is associated with a low morbidity. Importantly, through a unilateral robotic technique, it is possible to dissect and remove at least the same amount of mediastinal fat tissue. Preliminary results on early-stage thymomatous disease indicated that minimally invasive approaches are safe and feasible, with a low rate of pleural recurrence, underlining the necessity of a "no-touch" technique. However, especially for thymomatous disease characterized by an indolent nature, further studies with long follow-up period are necessary in order to assess oncologic and neurologic results through minimally invasive

However, VATS is associated with several disadvantages. For this reason, it is not routinely performed for resection of mediastinal mass lesions, especially those located in the anterior mediastinum, a tiny and remote space that contains vital structures at risk of injury. Robotic systems can overcome the limits of VATS, offering three-dimensional (3D) vision and wristed instrumentations, and are being increasingly used. With regards to thymectomy for myasthenia gravis (MG), unilateral and bilateral VATS approaches have demonstrated good long-term neurologic results with low complication rates. Nevertheless, some authors still advocate the necessity of maximum exposure, especially when considering the distribution of normal and ectopic thymic tissue. In recent studies, the robotic approach has shown to provide similar neurological outcomes when compared to transsternal and VATS approaches, and is associated with a low morbidity. Importantly, through a unilateral robotic technique, it is possible to dissect and remove at least the same amount of mediastinal fat tissue. Preliminary results on early-stage thymomatous disease indicated that minimally invasive approaches are safe and feasible, with a low rate of pleural recurrence, underlining the necessity of a “no-touch” technique. However, especially for thymomatous disease characterized by an indolent nature, further studies with long follow-up period are necessary in order to assess oncologic and neurologic results through minimally

    Background Acute mediastinitis is a serious medical condition with a mortality rate of 30 to 40% or even higher. Early diagnosis with prompt and aggressive treatment is essential to prevent its rapid progression. We evaluated acute mediastinitis cases and analyzed the outcomes. Materials and Methods A retrospective chart review was conducted on patients diagnosed with acute mediastinitis who were admitted to Mofid Children's Hospital from January 2001 to January 2010. Results Seventeen patients aged 1 to 10 yrs. (mean =3.8 yrs) were evaluated including 12 (70%) boys and 5 (30%) girls. The most common symptoms were fever, dyspnea, cyanosis, tachycardia and tachypnea. The etiology of mediastinitis was iatrogenic esophageal perforation (EP), and related to manipulation in 13(77%), and leakage of esophageal anastomosis in 4 cases (33%). The underlying diseases were esophageal atresia in 2(12%), corrosive injury of the esophagus in 13(76%), congenital esophageal stenosis in one (6%), and gastroesophageal reflux esophagitis also in one (6%) patient. Patients with clinical symptoms were evaluated by immediate chest radiography, and gastrografin swallow. After early diagnosis, the patients received wide spectrum antibiotics and immediate mediastinal or thoracic drainage, followed by esophagostomy and gastrostomy. Only one case of endoscopic perforation was managed by NG tube. Fifteen patients (88%) survived successfully. We had 2(12%) cases of mortality in our study (one patient after esophageal substitution, mediastinal abscess and septicemia, and the other one developed esophageal perforation 6 months after early management and died of cardiac arrest during endoscopic dilation). Conclusion Prevention of acute mediastinitis is still a difficult challenge. As the prognosis is not good and patients have high mortality, rapid management is mandatory. PMID:25191462

    Acute mediastinitis is a fatal disease that usually originates from esophageal perforation and surgical infection. Rare cases of descending necrotizing mediastinitis can occur following oral cavity and pharynx infection or can be a complication of pancreatitis. The most common thoracic complications of pancreatic disease are reactive pleural effusion and pneumonia, while rare complications include thoracic conditions, such as pancreaticopleural fistula with massive pleural effusion or hemothorax and extension of pseudocyst into the mediastinum. There have been no reports of acute mediastinitis originating from pancreatitis in South Korea. In this report, we present the case of a 50-year-old female suffering from acute mediastinitis with pleural effusion arising from recurrent pancreatitis that improved after surgical intervention.

    Transcervical extended mediastinal lymphadenectomy (TEMLA) is a new procedure for bilateral excision of all nodal stations of the mediastinum, except for the pulmonary ligament nodes (station 9) and the most distal left lower paratracheal nodes (station 4L). The procedure is performed through a transverse 5-8 cm incision in the neck with elevation of the sternum with a traction device facilitating the access to the mediastinum. Most of the procedure is performed with an open technique, while the removal of the subcarinal (station 7) and periesophageal nodes (station 8) is performed with the mediastinoscopy assisted technique and excision of the paraaortic nodes (station 6), the aorta-pulmonary window nodes (station 5) and, sometimes, the prevascular nodes (station 3A) is performed with the aid of a videothoracoscope introduced to the mediastinum through the neck incision, without violating the pleura.

    Asthma is one of the most common chronic medical conditions affecting children. The usual presenting symptoms of asthma include wheezing, shortness of breath, and dyspnea on exertion. Occasionally, children who present with one of these respiratory complaints have a less common disorder. Mediastinal fibrosis is a rare and incurable condition in which an excessive fibrotic reaction in the mediastinum causes progressive cardiopulmonary compromise. The presentation is variable: many patients present with respiratory symptoms such as cough, wheezing, dyspnea, and/or hemoptysis, while others are asymptomatic and present with a mediastinal mass discovered incidentally on a radiograph. With such a broad array of presenting complaints, and a clinical course characterized by slow progression of symptoms, the early stages of mediastinal fibrosis can mimic other diseases such as asthma, chronic bronchitis, or the superior vena cava syndrome. In this report we describe two patients with mediastinal fibrosis who were initially thought to have asthma. PMID:9642434

    Despite modern intensive care management, acute mediastinitis is still associated with a high morbidity and mortality (up to approximately 40 %). Effective antibiotic therapy, intensive care management, elimination of the causative sources of infection and drainage of the affected mediastinal compartments are the cornerstones of therapy in a multidisciplinary treatment concept. Early diagnosis, prompt and uncompromising initial therapy and planned computed tomography (CT) control after the first stages of therapy in order to decide on the necessity for surgical re-interventions are essential for achieving optimal results. Knowledge of the specific anatomical characteristics is crucial for the understanding of this disease and its treatment; therefore, the current knowledge on fascial layers and interstitial spaces from the neck to the mediastinum is described and discussed. A possible foudroyant spread of the infection, especially within the posterior mediastinum, has to be anticipated. The approach to the mediastinum depends on the mediastinal compartments affected, on the causative disease and on the patient's clinical situation. The surgical approach should be adapted to the particular clinical situation of the individual patient and to the surgical experience of the surgeon. When in doubt, the more invasive approach to the mediastinum, such as bilateral thoracotomy, is recommended. An ascending mediastinitis due to pancreatitis is a very rare condition; however, as chest pains are often the main clinical sign surgeons should be aware of this differential diagnosis. An intraoperative brown-black serous fluid in the mediastinal tissue is virtually pathognomonic. The treatment results of esophageal perforation as the most frequent cause of mediastinitis have been improved by integration of various interventional procedures. Hyperbaric oxygen therapy or immunoglobulin treatment can play an auxiliary role in selected patients with acute mediastinitis. PMID

    The absence of radiation induced cardiac damage during the orthovoltage era, during which period much lower doses of radiation were delivered for mediastinal malignancies due to severe skin reactions, was misinterpreted as cardiac radioresistance. However, with the advent of supervoltage x-rays with skin sparing effect, much higher doses of irradiation have been given for mediastinal malignancies. This has resulted in higher doses of radiation to the heart resulting in various types of radiation induced cardiac damage. The most common site of damage is to the pericardium, resulting in pericardial effusion. The radiographic evidence of radiation induced pericardial effusion starts one to six months prior to signs and symptoms due to it. Most of the asymptomatic radiation induced pericardial effusions resolve spontaneously. The factors which appear to play a role in the development of radiation induced pericardial effusion are discussed. ImagesFigure 1Figure 2 PMID:7392078

    We report the rare and interesting case of a primary lung cancer detected 5 years after cancer of unknown primary (CUP) of a mediastinal lymph node (LN) was resected. A 40-year-old male was diagnosed with adenocarcinoma of unknown primary in a mediastinal lymph node after resection of the mediastinal tumor. Five years after resection of the CUP in mediastinal LN, a small, abnormal nodular shadow in left upper lobe was detected by chest CT. This pulmonary tumor was diagnosed as a lung adenocarcinoma. The pathological and immunohistological findings of the resected pulmonary tumor resembled those of the LN resected 5 years before. We speculated that the pulmonary lesion represented primary lung cancer that enlarged later than the metastatic mediastinal LN. This case illustrates the importance of careful observation and long-term follow-up in patients treated for CUP of a thoracic LN. PMID:26328596

    Hydatid disease is a parasitic infection that is remains endemic in many countries, particularly the Middle East and Central Asia. Mediastinal hydatidosis is very rare (less than 0.1% of all hydatid disease cases) that have been only anecdotally in the literature. To the best of our knowledge only one case of multiple mediastineal hydatid cysts has been reported previously. We report the second cases of multiple mediastineal hydatid cysts and recommend that it can be considered in the differential diagnosis of multiple cystic mediastineal masses in endemic countries.

    Our goal was to determine the prevalence of mediastinal lymph node enlargement at CT in patients with diffuse infiltrative lung disease. The study was retrospective and included 175 consecutive patients with diffuse infiltrative lung diseases. Diagnoses included idiopathic pulmonary fibrosis (IPF) (n = 61), usual interstitial pneumonia associated with collagen vascular disease (CVD) (n = 20), idiopathic bronchiolitis obliterans organizing pneumonia (BOOP) (n = 22), extrinsic allergic alveolitis (EAA) (n = 17), and sarcoidosis (n = 55). Fifty-eight age-matched patients with CT of the chest performed for unrelated conditions served as controls. The presence, number, and sites of enlarged nodes (short axis {ge}10 mm in diameter) were recorded. Enlarged mediastinal nodes were present in 118 of 175 patients (67%) with infiltrative lung disease and 3 of 58 controls (5%) (p < 0.001). The prevalence of enlarged nodes was 84% (46 of 55) in sarcoidosis, 67% (41 of 61) in IPF, 70% (14 of 20) in CVD, 53% (9 of 17) in EAA, and 36% (8 of 22) in BOOP. The mean number of enlarged nodes was higher in sarcoidosis (mean 3.2) than in the other infiltrative diseases (mean 1.2) (p < 0.001). Enlarged nodes were most commonly present in station 10R, followed by 7, 4R, and 5. Patients with infiltrative lung disease frequently have enlarged mediastinal lymph nodes. However, in diseases other than sarcoid, usually only one or two nodes are enlarged and their maximal short axis diameter is <15 mm. 11 refs., 2 figs., 1 tab.

    This review article describes minimally invasive thoracoscopic surgery for anterior mediastinal lesions. The operative procedures for anterior mediastinal lesions have been changed in a couple of decades from open surgery under median sternotomy to complete thoracoscopic mediastinal surgery with sternal lifting or carbon dioxide insufflation. Carbon dioxide insufflation of the thoracic cavity or the mediastinum is now prevailing to improve the surgical field and facilitate the operative procedures. Surgical indications for complete thoracoscopic mediastinal surgery include benign cystic lesions generally regardless of their size and non-invasive anterior mediastinal tumors usually less than 50~60 mm in the greatest dimension. There are currently three surgical approaches in the complete thoracoscopic surgery for the anterior mediastinal lesions. One is the unilateral or bilateral transthoracic approach. The second is the combination of the subxiphoid and the transthoracic approach. The last is the subxiphoid approach. The selection of the surgical approach depends on the surgeon's preference and experiences. When carbon dioxide insufflation is applied during the operation, following complications may occur;hypercapnia, gas embolism, subcutaneous emphysema, endotracheal tube dislocation due to the mediastinal sift, and hypotention. Special safety considerations are necessary during the complete thoracoscopic mediastinal surgery with carbon dioxide insufflation. PMID:27440034

    Introduction Mediastinal localization of hydatidosis is very rare even in endemic areas. The diagnosis is based on typical clinical and radiological criteria. Case presentation We report a case of a mediastinal location of hydatidosis in a 60-year-old Arab man admitted for chest pain. The chest radiograph showed a rounded and homogeneous opacity. Computed tomography showed a right mediastinal cyst, without other thoracic or abdominal sites. Through a posterolateral thoracotomy, we found a cystic mass in the posterior mediastinum. The patient received a cystectomy with medical treatment based on albendazole. He improved a few weeks later. Conclusion Mediastinal cysts remain rare, even in endemic countries, which makes initial diagnosis difficult. Our observation shows the importance of keeping this diagnosis in mind when a patient presents with signs of mediastinal compression. PMID:24099329

    The recent World Health Organization (WHO) classification defines mantle cell lymphoma (MCL) as a distinct entity characterized by a unique immunophenotype and a molecular hallmark of chromosomal translocation t(11;14)(q13;q32). We report an unusual case of an advanced stage of CD5 negative MCL with a blastoid variant with a massive bone marrow (BM) necrosis as an initial presenting feature, with no adenopathy or hepatosplenomegaly. The pathologic features showed blastoid variant of MCL and flow cytometry showed that the tumor cells were CD5−, CD19+, CD20+, FMC-7+, CD23−, and lambda light chain restricted. Chromosomal analysis, using karyotype and fluorescent in situ hybridization (FISH), demonstrated karyotypic abnormalities in addition to the t(11;14). Our case study may be reported as a unique case of CD5− blastic MCL with unusual presentation and findings which made the diagnosis of MCL difficult. PMID:26347832

    Lipomatous hypertrophy of the interatrial septum (LHIS) is an uncommon cause of superior vena cava syndrome (SVCS). Fibrosing mediastinal lymphadenopathy is another cause of SVCS. We present a 65-year-old female patient with a history of tuberculosis (TB) and the coexistence of LHIS and fibrosing mediastinitis due to TB of the lung. Fibrosing or sclerosing mediastinitis is a rare entity with few cases published in the western literature. She presented with mild symptomatology of SVCS and she underwent on transthoracic and transesophageal echocardiography, computed tomography scan, magnetic resonance imaging, and venography. Due to the development of an abundant collateral venous system seen on venography and her negation for any treatment, she did not undergo yet on any intervention. To our knowledge, this is the first case reported in the international bibliography in which LHIS and sclerosing lymphadenopathy are simultaneously diagnosed in the same patient. PMID:26440257

    Using a size criterion of 1 cm or greater as evidence for abnormality, the size of mediastinal lymph nodes identified by computed tomography (CT) was a poor predictor of mediastinal lymph node metastases in a series of 86 patients who had surgery for bronchogenic carcinoma. The surgery included full nodal sampling in all patients. Of the 86 patients, 36 had nodes greater than or equal to 1 cm identified by CT. Of the 21 patients with mediastinal metastases proven at surgery, 14 had nodes greater than or equal to 1 cm (sensitivity = 67%). Of the 65 patients without mediastinal metastases, 22 had nodes greater than or equal to 1 cm. Specificity was 66% (43/65). Obstructive pneumonia and/or pulmonary collapse distal to the cancer was present in 39 patients (45%). Of these, 21 had mediastinal nodes greater than or equal to 1 cm; 10 harbored metastases and 11 did not. Obstructive pneumonia and/or pulmonary collapse is a common occurrence in bronchogenic carcinoma, but mediastinal nodes greater than or equal to 1 cm in this circumstance cannot be presumed to represent metastatic disease. Metastatic mediastinal lymph node involvement was related to nodal size also in patients with evidence of prior granulomatous disease and in patients with no putative benign cause for nodes greater than or equal to 1 cm. In both of these groups, metastatic nodal disease was found in only 25% of nodes greater than or equal to 1 cm. PMID:6332469

    Background To report the first series of video-assisted thoracoscopic surgery (VATS) resection of mediastinal ectopic parathyroid adenomas (MEPAs) in the UK. Methods A case series of seven cases undergoing VATS between 2004 and 2009 to treat single gland hyperparathyroidism. Methylene blue (MB) was used in 5/7 cases immediately before exploration to identify the adenomas. Carbon dioxide (CO2) up to pressures of 10 mmHg was used safely to deflate the lung in two cases. Results There were five women and two men with a mean age of 53 years (range, 27-72 years). Histopathology confirmed successful resection of the parathyroid adenoma in 6/7 cases. There was one conversion to open thoracotomy due to bleeding from the azygos vein resulting from excessive traction. Despite marked MB uptake, this patient proved to have tuberculoid adenopathy and no parathyroid tissue was identified. Postoperative plasma calcium returned to normal in 6/7 patients and parathyroid hormone (PTH) level in 6/7 patients. The median hospital stay was 2 days and there was no mortality in this series. Conclusions MEPAs can be safely resected using VATS with minimal surgical morbidity, short drainage time and short hospital stay. CO2 insufflation and the intraoperative use of MB are safe and help to accurately localise the ectopic adenoma. VATS should be considered as the first-line approach for resection of MEPAs.

    An 80-year-old woman was admitted to a local hospital following transient disturbance of consciousness after a fall. High intermittent fever developed after hospitalization and she was diagnosed as having mediastinal abscess with esophageal perforation. She underwent mediastinal drainage and surgical repair of the esophagus. Acid-fast bacilli were detected in her sputum. Chest CT scanning showed a diffuse granular shadow. Then she was diagnosed as having miliary tuberculosis and treated with combination of INH, RFP, EB, and PZA. However, five days after treatment was initiated, fever and skin eruption appeared and treatment has to be stopped after one month. Then she was referred to our hospital. We gradually increased the dosages of INH and RFP, which resulted in pyrexia. Therefore, we changed EB to SM. Fever subsided and we were able to administer the full dose of drugs from the beginning of January 2007. Thereafter, the patient improved gradually. However, she died in February 2007. At autopsy, we identified tuberculous mediastinal lymphadenitis, inflammatory granuloma under the esophageal mucosa and miliary tuberculosis. We report this case as a rare case of miliary tuberculosis and esophageal perforation secondary to tuberculous mediastinal lymphadenitis. PMID:19425392

    Introduction Progress in the development of surgical techniques has led to the growing use of video-assisted thoracoscopic surgery (VATS) techniques in mediastinal cyst treatment. Aim To present our experience of treating mediastinal cysts with the minimally invasive technique. Material and methods Fifty patients with mediastinal cysts were treated from 2001 to 2011. There were 32 women and 18 men. The age of the patients ranged from 17 to 72, the mean age being 42 years. All patients underwent basic preoperative diagnostic tests of the chest: X-ray, computed tomography (CT), bronchoscopy and spirometry; 4 patients underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and 3 fine needle aspiration biopsy (FNAB) of the described lesions. Results The VATS was performed in each case. Conversion was carried out due to superior mediastinal location in 10 cases and pleural adhesions in 3 cases. The partial resection of a cyst was performed in 3 patients. One patient was treated conservatively due to heart failure. In that patient the transthoracic needle aspiration of a cyst under ultrasound guidance using alcoholisation with 76% ethanol with a good effect was performed twice. Cyst recurrence was observed in 1 case. Conclusions The surgical access depends on the location of a cyst. The VATS resection of a superior mediastinal cyst is not always feasible. Surgery of mediastinal cysts is both diagnostic and curative. PMID:25337163

    2013-01-01

    Background Descending necrotizing mediastinitis (DNM), a severe infection with a high fatality rate, develops in mediastinal spaces due mainly to deep cervical abscesses. The majority of causative microbes of DNM are Streptococci and oral anaerobes. DNM associated with Lactobacillus-infection is rather rare. Case presentation A 69-year-old male with an unremarkable past medical history was referred to our hospital for surgical resection of advanced laryngeal cancer. Full examination revealed a neck abscess and DNM with a background of untreated diabetes mellitus. Initially, he was treated with meropenem. However, Lactobacillus plantarum was isolated from surgical drainage of a mediastinal abscess. Despite using antibiotics capable of eradicating all isolates with susceptibilities not differing significantly from those of the neck and mediastinal abscesses, we attributed DNM to the L. plantarum detected only in the mediastinal abscess. After DNM treatment, he underwent total pharyngolaryngectomy with bilateral neck dissection followed by reconstruction using free jejunum. He was discharged fully recovered. Conclusion We concluded that L. plantarum as the sole cause of the mediastinal abscess in the present case cannot be ruled out. As the number of immunocompromised patients increases, we should be cautious regarding this “familiar” microbe. PMID:23987907

Of the 65 patients without mediastinal metastases, 22 had nodes greater than or equal to 1 cm. Obstructive pneumonia and/or pulmonary collapse distal to the cancer was present in 39 patients (45%). Obstructive pneumonia and/or pulmonary collapse is a common occurrence in bronchogenic carcinoma, but mediastinal nodes greater than or equal to 1 cm in this circumstance cannot be presumed to represent metastatic disease. Metastatic mediastinal lymph node involvement was related to nodal size also in patients with evidence of prior granulomatous disease and in patients with no putative benign cause for nodes greater than or equal to 1 cm.

    Mediastinitis occurs as a severe complication of thoracic and cardiac surgical interventions and is the result of traumatic esophageal perforation, conducted infections or as a result of lymphogenic and hematogenic spread of specific infective pathogens. Treatment must as a rule be accompanied by antibiotics, whereby knowledge of the spectrum of pathogens depending on the pathogenesis is indispensable for successful antibiotic therapy. Polymicrobial infections with a high proportion of anaerobes are found in conducted infections of the mediastinum and after esophageal perforation. After cardiac surgery Staphylococci are the dominant pathogens and a nasal colonization with Staphylococcus aureus seems to be a predisposing risk factor. Fungi are the predominant pathogens in immunocompromised patients with consumptive underlying illnesses and can cause acute or chronic forms with granulomatous inflammation. Resistant pathogens are increasingly being found in high-risk patient cohorts, which must be considered for a calculated therapy. For calculated antibiotic therapy the administration of broad spectrum antibiotics, mostly beta-lactams alone or combined with metronidazole is the therapy of choice for both Gram-positive and Gram-negative bacteria inclusive of anaerobes. For patients at risk, additional antibiotic classes with a spectrum against methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) can be administered. Increasing rates of multidrug-resistant Gram-negative bacteria (e.g. Enterobacteriaceae) and non-fermenting bacteria (e.g. Pseudomonas and Acinetobacter) in individual cases necessitates the use of polymyxins (e.g. colistin), new tetracyclines (e.g. glycylglycines) and newly developed combinations of beta-lactams and beta-lactam inhibitors. For treatment of fungal infections (e.g. Candida, Aspergillus and Histoplasma) established and novel azoles, amphotericin B and echinocandins seem to be successful; however

    Between 1973 and 1989, 16 children with non-Hodgkins lymphoma (NHL) with a mediastinal mass (MM) were treated at our institution with multi-agent chemotherapy and radiotherapy. They also received central nervous system (CNS) prophylaxis including intrathecal methotrexate administration (14 cases) and cranial irradiation (7 cases). Twelve were boys and 4 girls. Median age was 11 +/- 3. One patient died of air way obstruction one day after admission. Fourteen of 15 patients entered into complete remission (CR) and one patient partial remission. Five remains in CR 7 to 175 months after diagnosis (median 76 months). Nine patients relapsed in the bone marrow (3 cases), CNS (3), testicles (1), neck lymph node (1) and bones plus kidneys (1). Of these, 7 patients died within 13 months after initial relapse. The disease free survival (DFS) and overall survival of all patients were 27% and 33%, respectively. Analysis of the prognostic factors among patients with MM+ -NHL revealed that the serum LDH level below 1,000IU/l was a good prognostic sign. Other factors such as age, stage, initial WBC count, size of MM and response of the MM to the initial treatment did not correlate with DFS. Because of its rarity and the poor treatment result, we need more aggressive treatment program by a multiinstitutional study for MM+ -NHL. PMID:2287064

    Introduction. Mediastinitis has been reported to complicate 5% of sternotomy surgery. We have adopted an open reduction and rigid internal fixation (ORIF) approach during the conventional rescue surgery in the treatment of mediastinitis. Methods. A retrospective review was performed to compare the outcomes of patients that had an ORIF to correct postoperative mediastinitis following median sternotomy. These were compared with the outcome of the patients that did not undergo ORIF. Results. In the 5-year study period, we reviewed 35 mediastinitis patient charts. Postoperatively, the ORIF patient group remained in the Intensive Care Unit (ICU) and on a ventilator for a mean of 1.5 and 0.75 days, respectively. Patients treated without ORIF spent significantly more days in the ICU (mean of 7.5 days, P < 0.05) and on a ventilator (mean of 2.15 days, P = 0.1). Furthermore, it was found that none of the patients (0%) who underwent ORIF complained of any postoperative sternal instability or pain. Preoperatively, however, these rates were as high as 72%. Conclusions. In the select patient, ORIF can be a safe option in the management of mediastinitis, which we have shown to significantly decrease morbidity and mortality by providing anatomic reduction as well as physiologic stabilization. We have shown that ORIF will improve the quality of life of the patient by minimizing abnormal sternal mobility and pain and will also decrease inpatient costs by decreasing days spent in the ICU and ventilator dependence.

    Division of the mediastinum into compartments is used to help narrow the differential diagnosis of newly detected mediastinal masses, to assist in planning biopsy and surgical procedures, and to facilitate communication among clinicians of multiple disciplines. Several traditional mediastinal division schemes exist based upon arbitrary landmarks on the lateral chest radiograph. We describe a modern, computed tomography-based mediastinal division scheme, which has been accepted by the International Thymic Malignancy Interest Group as a new standard. This clinical classification defines a prevascular (anterior), a visceral (middle), and a paravertebral (posterior) compartment, with anatomic boundaries defined clearly by computed tomography. It is our intention that this definition be used in the reporting of clinical cases and the design of prospective clinical trials. PMID:25396318

    Angiomyolipomas are benign, solitary, noninvasive lesions that most often arise in the kidney. Extrarenal manifestations of these tumors include the skin, oropharynx, the abdominal wall, retroperitoneum, gastrointestinal tract, heart, lung, liver, uterus, penis, and spinal cord. We report a patient with a giant angiomyolipoma located in the anterior mediastinum. We believe this is the seventh reported case of mediastinal angiomyolipoma and the largest reported by size. It is the second reported lesion to arise in the anterior mediastinum. Distinction from other pulmonary or thoracic masses relies on the appreciation of the unique and characteristic histologic features of these mediastinal angiomyolipomas. We conclude that, although rare, angiomyolipoma should be considered in the differential diagnosis of a mediastinal tumor. PMID:15561061

    Mediastinal germ cell tumours (teratomas, seminomas, and non-seminomatous malignant germ cell tumours) are a heterogeneous group of benign and malignant neoplasms. The standard treatment of mediastinal non-seminomatous malignant germ cell tumours is four cycles of chemotherapy followed by surgical resection of the residual mass. Small localized mediastinal seminomas may be treated with primary resection followed by radiotherapy. In patients with locally advanced disease, the preferred treatment is systemic chemotherapy followed by surgical resection of any residual disease. Thymomas can be locally invasive and associated with parathymic syndromes. Complete surgical excision is attempted in most cases of thymoma. Radiation therapy is usually recommended for invasive or incompletely excised tumours. Invasive thymoma is chemosensitive. PMID:17268355

    Descending necrotizing mediastinitis (DNM) is a rare condition in which oropharyngeal infection spreads to the mediastinum via the cervical fascia. Delayed diagnosis and surgery result in a high mortality rate among patients with DNM. We present a case of DNM resulting from odontogenic infection treated successfully with tooth extraction following mediastinal and cervical drainage. A 43-year-old, previously healthy Japanese man was admitted to our hospital for treatment of acute mediastinitis. Computed tomography revealed gas collection around the mid-thoracic esophagus and bilateral pleural effusion. We performed mediastinal drainage via right thoracotomy. Cervicotomy was performed on postoperative day 14 to drain a residual cervical abscess. The patient required the extraction of ten teeth over three procedures to address primary odontogenic infection before his fever resolved on postoperative day 40. Prompt diagnosis, aggressive drainage and removal of the source of infection can improve survival among patients with this life-threatening disease. PMID:26600767

    The advent of endoscopic ultrasound-guided sampling procedures such as endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has lead to significant advances in the mediastinal diagnosis and staging of lung cancer. These endoscopic techniques can be performed in the outpatient setting under conscious sedation and local anesthesia, in contrast to the surgical standard, mediastinoscopy (MS), which requires operating theatre time and general anesthesia. Proponents of mediastinoscopy have always emphasized the advantages of mediastinoscopy, namely its sensitivity even with a low prevalence of mediastinal metastases and its low false negative rate. Newer endoscopic techniques such as EBUS-TBNA are showing sensitivities exceeding that of mediastinoscopy, even in the setting of an equally low prevalence of mediastinal metastases. However, endoscopic techniques have double the false negative rate of mediastinoscopy. As the tracheobronchial route and esophageal route provide almost complete access to mediastinal lymph nodes, these endoscopic techniques are complementary rather than competing. When used in combination, it is possible mediastinoscopy may be superseded. The challenge however, is how best to select the appropriate endoscopic procedures to accurately stage lung cancer in the most cost-effective manner. PMID:21130638

    Extragonadal yolk sac tumors (YSTs) are rare. We herein report the case of a 66-year-old man with mediastinal, lung and liver tumors. The largest mass was located in the liver and contained a high concentration of protein induced by vitamin K absence or antagonist-II (PIVKA-II) and alpha-fetoprotein. Therefore, the lesion was difficult to distinguish from hepatocellular carcinoma. Finally, YST was diagnosed based on the results of a liver biopsy. Although chemotherapy was effective, the patient died of respiratory failure. The autopsy revealed primary mediastinal YST. In the current report, we describe this case of PIVKA-II-producing YST and review previous cases of PIVKA-II-producing tumors other than hepatoma. PMID:26073245

    Primary mediastinal desmoplastic small round cell cancer is an uncommon tumour usually located in the abdomen and pelvis. Here the authors report an extremely rare case of a young male with a primary desmoplastic small round cell tumour in the anterior and middle mediastinum. The patient had non-specific complaints but an abnormal shadow was seen in a routine chest x-ray. He was diagnosed as having mediastinal mass with few lung parenchymal deposits on CT. Mediastinoscopy and guided biopsy revealed desmoplastic small round cell tumour. Desmoplastic small round cell tumour is a rare and aggressive tumour which rarely involves the mediastinum as a primary site. The nature of the lesion and its prognosis were explained to the patient. He was offered chemotherapy and radiotherapy for the tumour management. He refused treatment and left against medical advice. PMID:22670008

    Multicentric Castleman's disease is a polyclonal lymphoproliferative disorder. Recently, a new variant of the disease was reported and named TAFRO syndrome, an acronym for thrombocytopenia, ascites, myelofibrosis, renal dysfunction, and organomegaly. A 55-year-old woman presented to our hospital with dyspnea on exertion and high fever. Laboratory tests revealed anemia, thrombocytopenia, and proteinuria. Computed tomography (CT) revealed a large anterior mediastinal mass, mild splenomegaly, bilateral pleural effusion, pericardial effusion, and mild systemic lymphadenopathy. A CT-guided biopsy was unable to establish a definitive diagnosis, so we resected the mediastinal mass for diagnostic and therapeutic purposes. Pathological findings were consistent with the hyaline vascular type of Castleman's disease (CD), and she was diagnosed with TAFRO syndrome. There has been no description of a patient with TAFRO syndrome with a large mass, and this is the first case of TAFRO syndrome treated with debulking surgery. PMID:27316721

    Thoracic CT scans were performed on 42 newly diagnosed patients with Hodgkin's disease. Five of 10 patients with negative chest X ray (CXR) had abnormal thoracic CT scans. Among the remaining 32 patients with mediastinal Hodgkin's disease (MHD) on CXR, pericardial (Ep) and chest wall invasion (Ec) were the two most common sites of involvement which were detectable by CT scan alone. Ep and Ec accounted for 16 of 19 of the changes in treatment portal or philosophy based on CT scan findings. Because of the high risk of cardiac or pulmonary radiation toxicity in Ep or Ec, radiation treatment alone may be inadequate. Treatment of mediastinal Hodgkin's disease is reviewed here. The use of CT scans for identification of Ep, Ec, and other abnormalities will allow for more precise treatment, further define the use of conventional radiotherapy, combined modality therapy or whole lung irradiation, and allow more accurate analysis of treatment results.

    Desmoid tumors (DTs) are a group of rare and benign soft tissue tumors that result from monoclonal proliferation of well-differentiated fibroblasts. Since DTs tend to infiltrate and compress adjacent structures, the location of DTs is one of the most crucial factors for determining the severity of the disease. Furthermore, DTs can further complicate the clinical course of patients when the growth is remarkably rapid, especially for DTs occurring in anatomically critical compartments, including the thoracic cavity.The authors report a case of a 71-year-old man with a known mediastinal mass incidentally detected 4 months ago, presenting dyspnea with right-sided atelectasis and massive pleural effusion. Imaging studies revealed a 16.4 × 9.4-cm fibrous mass with high glucose metabolism in the anterior mediastinum. The mass infiltrated into the chest wall and also displaced the mediastinum contralaterally. Interestingly, the tumor had an extremely rapid doubling time of 31.3 days.En bloc resection of the tumor was performed as a curative as well as a diagnostic measure. Histopathologic examination showed spindle cells with low cellularity and high collagen deposition in the stroma. Immunohistochemical staining was positive for nuclear β-catenin. Based on these pathologic findings, the mass was diagnosed as DT. After surgery, there has been no evidence of recurrence of disease in the patient.This patient presents a mediastinal DT with extremely rapid growth. Notably, the doubling time of DT in our case was the shortest among reported cases of DT. Our experience also highlights the benefits of early interventional strategy, especially for rapidly growing DTs in the thoracic cavity. PMID:26717381

    Descending necrotizing mediastinitis secondary to a nontraumatic retropharyngeal abscess is very rare. This form of mediastinitis in the era of potent antibiotics often ends up with lethal outcome. It usually occurs in immunocompromised patients and requires intensive multidisciplinary treatment approach. We report a case of nontraumatic retropharyngeal abscess complicated by descending necrotizing mediastinitis in a 70-year-old man with insulin dependent diabetes mellitus. The patient was admitted to our hospital after clinical and radiological diagnosis of retropharyngeal abscess. During treatment for retropharyngeal abscess with antibiotic therapy and transoral incision, the patient showed mild clinical improvement but his condition suddenly aggravated on day 4 of hospital stay. He had high fever, chest pain with tachypnea, tachycardia, hypotension, and showed signs of occasional disorientation. Emergency computed tomography (CT) scan of the neck and thorax showed inflammation in the retropharyngeal space, as well as thickening of the upper posterior mediastinum fascia with the presence of air. Emergency surgery including cervicotomy and drainage of the retropharyngeal space and posterior mediastinum was performed. The patient promptly recovered with improvement of the clinical status and laboratory findings. After 16 days of treatment he was discharged from the hospital in good condition. Descending necrotizing mediastinitis can be a serious and life threatening complication of deep neck infection if the diagnosis is not quickly established. Besides inevitable application of antimicrobial drugs, good drainage of the mediastinum is necessary. We believe that transcervical approach can achieve high-quality drainage of the upper mediastinum, especially if it is done timely as in this case. Its efficacy can be verified by intensive monitoring of the patient clinical condition, by CT scan of the thorax, and by laboratory tests. In the case of inefficacy of this type

    Abstract Descending necrotizing mediastinitis (DNM) is a potentially lethal disease that originates from a deep neck infection (DNI); it is often associated with an immunocompromised state. Hyperimmunoglobulin E syndrome (HIES) is an extremely rare complex immune deficiency characterized by recurrent abscesses of staphylococcal etiology. A rare case of a 34‐year‐old woman wherein HIES putatively promoted the development of DNI into DNM is described. She presented with cervical purulent lymphadenitis and retropharyngeal abscess. Despite immediate cervical drainage and use of broad‐spectrum antibiotics, she developed DNI and subsequently DNM. Mediastinal drainage with thoracotomy and subsequent deep neck drainage were performed. Bacterial culture of the abscess isolated methicillin‐resistant Staphylococcus aureus (MRSA). Although a postoperative recurrent deep neck abscess required a second surgery, we succeeded in conservative remission of recurrent mediastinal abscess with long‐term use of anti‐MRSA drugs. Sufficient drainage under thoracotomy and robust administration of postoperative antibiotics resulted in successful management of HIES‐associated DNM. PMID:27512566

    Thrombocytopenia (T), anasarca (A), myelofibrosis (F), renal dysfunction (R), and organomegaly (O) (TAFRO) syndrome is a variant of multicentric Castleman's disease. We describe here a 57-year-old man who presented with persistent fever, pleural effusion, and ascites. He was negative for human immunodeficiency virus and human herpes virus-8. A computed tomography scan showed an anterior mediastinal mass and small inguinal lymphadenopathy. Although a biopsy of the anterior mediastinum showed fatty tissue infiltrated with CD20 (+) and CD45RO (+) lymphocytes, a biopsy of the left inguinal lymph node revealed a hyaline vascular type of Castleman's disease. He subsequently developed severe thrombocytopenia and renal dysfunction. In addition, his bone marrow biopsy showed myelofibrosis. TAFRO syndrome was diagnosed based on the lymph node pathology and the characteristic manifestations of the syndrome. Tocilizumab and glucocorticoid therapy achieved complete remission and regression of the mediastinal mass. To our knowledge, this is the first report of TAFRO syndrome accompanied by an anterior mediastinal mass, which responded very well to therapy. PMID:27516889

    We report a rare case of mediastinal follicular dendritic cell (FDC) sarcoma involving the bone marrow. The patient, a 46-year-old woman, had a clinically aggressive tumor in the anterior mediastinum that was initially diagnosed as a diffuse B-cell lymphoma. She received chemotherapy but showed no significant improvement. One year later, the patient presented at our institution with pelvic bone metastases. Biopsy specimens of the sacrum lesion and bone marrow were obtained. The diagnosis of FDC sarcoma was made based on histological examination and immunohistochemical findings, including strong positive staining of tumor cells for CD21, CD23, clusterin, and epidermal growth factor receptor (EGFR) and negative staining for CD20, CD30, CD45, CD1a, S-100, vimentin, and keratin cocktail. Histological examination and immunohistochemical studies of a previous biopsy of the mediastinal mass confirmed the diagnosis of mediastinal FDC sarcoma. The patient was treated with an appropriate chemotherapy regimen; 1 month later, follow-up bone marrow biopsy revealed no tumor cells. Although FDC sarcoma is considered a low-grade tumor, the tumor in the present case not only developed at an unusual location with bone metastasis but also involved bone marrow. To our knowledge, this is the first such case ever reported. This case also highlights the utility of EGFR as an immunohistochemical marker of dendritic cell tumors that could be used as a diagnostic tool and guide for choosing appropriate chemotherapy regimens.

We report a case of Nocardia farcinica induced mediastinitis and pneumonia that occurred in a 64-year-old male patient who had no significant medical history except for hypertension. He visited another hospital with a complaint of dyspnea and left chest wall pain. The symptoms arose 7 days ago without any trauma and they worsened. A mediastinal mass was found on computed tomography scan. After being transferred to our hospital for further evaluation, he was diagnosed with mediastinitis and pneumonia. As N. farcinica was found to be the causative organism by 16S rRNA sequencing, proper antibiotic therapy including trimethoprim/sulfamethoxazole was initiated immediately. After this, the patient improved and he was discharged. If an infection has a disseminating course, nocardiosis cannot be excluded even in immunocompetent patients. Once the diagnosis is established, prompt antibiotic therapy should be performed based on the severity. PMID:27066088

    A 2.75-yr-old female American black bear (Ursus americanus) was found emaciated and unable to rise. It was euthanized due to the perceived poor prognosis. An approximately 18 x 8 x 10-cm, multiloculated, well-demarcated mass that extended from the bifurcation of the trachea, laterally displacing the lung lobes and caudally displacing the heart. The mass contained fibrous connective tissue, cartilage, bone, nervous tissue, smooth muscle, and a variety of epithelial structures. A mediastinal teratoma was diagnosed based on the microscopic features of the neoplasm. PMID:24450083

    Tumors involving the heart during childhood are rare. However, neuroblastoma, a common pediatric malignancy, has been described to involve the cardiovascular system in 3%-12% of patients dying with this tumor. Rarely is such involvement diagnosed ante mortem and never, to our knowledge, has a benign cardiac tumor been reported to present in childhood after successful eradication of neuroblastoma. We describe the identification and surgical resection of a nodular, hypertrophied, calcified, pedunculated left atrial mass in a 16-year-old boy who was complaining of exercise-associated presyncope and headaches 16 years after irradiation and chemotherapy for mediastinal neuroblastoma.

    Fibrosing mediastinitis is a rare condition defined by the presence of fibrotic mediastinal infiltrates that obliterate normal fat planes. It is a late complication of a previous granulomatous infection, such as histoplasmosis or tuberculosis (TB). Due to its rarity, fibrosing mediastinitis is often under-recognized, and the clinical presentation is variable and dependent on the extent of infiltration or encasement of structures within the mediastinum. We present a case of fibrosing mediastinitis in a man with a prior history of TB, who presented with progressive dyspnea and was found to have chronic mediastinal soft tissue opacities and pulmonary hypertension. His diagnosis was delayed due to the lack of recognition of this clinical/radiographic entity. Fibrosing mediastinitis is a rare entity usually caused by granulomatous disease. Most cases develop as a late complication of histoplasmosis or TB. The presence of calcified mediastinal soft tissue infiltrates on advanced chest imaging can be diagnostic of fibrosing mediastinitis in patients with a prior history of a granulomatous infection once active processes such as malignancy are excluded.

    A 6-year-old boy had an abnormal shadow on the chest X-ray film. It showed a tumor shadow with calcification on the right hilum. The plain CT scan showed an anterior mediastinal mass and its density was similar to that of large vessels. On the angio CT scan the lesion displayed a much lower enhancement than large vessels. The tumor was resected completely by median sternotomy. It was 5.6 X 3.6 X 3.0 cm in size and contained a phlebolith 5 mm in diameter. The histological diagnosis was cavernous hemangioma.

    Angiomatosis refers to a rare condition of large hamartomatous vascular lesions that extensively affect a region of the body or several different tissue types in a contiguous way. Several cases have been reported in the mediastinum. We experienced a histologically proven case of mediastinal angiomatosis in a 56-year-old woman that was incidentally detected as multiple conglomerated masses mimicking metastatic lymph nodes on chest radiography. Despite its rareness, our case emphasizes that pathologists and radiologists need to be aware of the rare diagnosis of angiomatosis in the mediastinum. PMID:26793386

    Mediastinal teratoma is an infrequent germ cell tumour and comprises of 1 to 5% of all mediastinal tumours. We report a case of mediastinal mature teratoma in a 12 year old boy who presented to us with persistent non-productive cough, fever and dyspnoea for the past 7 months. Computed tomographic scan of thorax revealed a large anterior mediastinal mass measuring 11.2x9.9x14cm with calcification within. He subsequently underwent a median sternotomy with left subcostal extension (L-incision) and excision of tumour. Histopathology of the tumour revealed a mature cystic teratoma. We would like to report a case of successful surgical management of a large mediastinal mature teratoma in a child. PMID:27130743

    Mediastinal germ cell tumours (MGCT) are rare and most published series reflect the experiences of individual institutions over many years. Since 1979, we have treated 16 men (12 non-seminomatous germ cell tumours and 4 seminomas) with newly diagnosed primary MGCT with POMB/ACE chemotherapy and elective surgical resection of residual masses. This approach yielded complete remissions in 15/16 (94%) patients. The median follow-up was 6.0 years and no relapses occurred more than 2 years after treatment. The 5 year overall survival in the non-seminomatous germ cell tumours (NSGCT) is 73% (95% confidence interval 43-90%). One patient with NSGCT developed drug-resistant disease and died without achieving remission and 2 patients died of relapsed disease. In addition, 4 patients with bulky and/or metastatic seminoma were treated with POMB/ACE. One died of treatment-related neutropenic sepsis in complete remission and one died of relapsed disease. Finally, 4 patients (2 NSGCT and 2 seminomas) referred at relapse were treated with POMB/ACE and one was successfully salvaged. The combination of POMB/ACE chemotherapy and surgery is effective management for MGCT producing high long-term survival rates. PMID:9291802

    Mixed phenotype acute leukemia symbolizes a very small subset of acute leukemia that simply cannot be allocated as lymphoid or myeloid lineage. The 2008 World Health Organisation classification established stringent standard for diagnosis of mixed phenotype acute leukemia, accentuating myeloperoxidase for myeloid lineage, cytoplasmic CD3 for T lineage and CD19 with other B markers for B lineage obligation. Mixed phenotype leukemia is rare and 3-5 % of acute leukmias of all age groups, is associated with poor outcome with overall survival of 18 months. We wish to present two cases of mixed phenotypic acute leukemia who presented with mediastinal masses, were suspected to be T cell lymphoma/leukemia clinically and radiologically. In one case, tissue diagnosis was given as lymphoma for which treatment was given. These cases show that patients diagnosed as lymphoma on histopathology can be cases of mixed phenotype acute leukemia and varying specific treatment protocols and follow up are required. Awareness of these entities will help in proper diagnosis and treatment. PMID:27408360

    Teratomas are germ cell tumors, manifested with a great variety of clinical features; the most common extragonadal site is the anterior mediastinum. In this case, we report the patient with a large mature mediastinal teratoma with several components of ectodermal and endothermal epithelium. A 24-year-old female patient presented with history of persistent chest pain and progressively aggravating dyspnea for the previous 3 months. A chest X-ray showed a large opacity of the entire left hemithorax. Transcutaneous needle aspiration revealed a purulent fluid. The tube thoracostomy was introduced and the effusion was evacuated. Some weeks later, patient was seen in emergency for persistent cough and lateral chest pain. CT scan revealed a mass of the left hemithorax. The mass showed heterogeneous density, without compressing mediastinum great vessels and left hilar structures. Lipase value was elevated in needle aspiration. The patient underwent a total resection of the mediastinum mass via a left posterolateral thoracotomy. Microscopy revealed a mature teratoma with cystic structures. The patient subsequently made a full recovery. This case provide benign mediastinal teratoma with total atelectasis of left lung and elevated lipase value in needle transcutaneous aspiration; this event is explained by pancreatic component in the cystic tumor. Total removal of the tumor is adequate treatment for this type of teratoma and the prognosis is excellent. PMID:27144046

    Esophageal perforation is a condition associated with high morbidity and mortality rates; it requires early diagnosis and treatment. The most common complication of esophageal rupture is mediastinitis. There are several case reports in the literature of mediastinitis secondary to esophageal perforation and development of aortic pseudoaneurysm as a complication. We report the case of a patient with an 8-day history of esophageal perforation due to foreign body (fishbone) with mediastinitis and aortic pseudoaneurysm. The diagnosis was made using Computed Tomography (CT) with intravenous and oral water-soluble contrast material. An esophagogastroduodenoscopy did not detect the perforation. PMID:26977330

    Large mediastinal masses are rare, and encompass a wide variety of diseases. Regardless of the diagnosis, all large mediastinal masses may cause compression or invasion of vital structures, resulting in respiratory insufficiency or hemodynamic decompensation. Detailed preoperative preparation is a prerequisite for favorable surgical outcomes and should include preoperative multimodality imaging, with emphasis on vascular anatomy and invasive characteristics of the tumor. A multidisciplinary team should decide whether neoadjuvant therapy can be beneficial. Furthermore, the anesthesiologist has to evaluate the risk of intraoperative mediastinal mass syndrome (MMS). With adequate preoperative team planning, a safe anesthesiological and surgical strategy can be accomplished. PMID:27076967

Rheumatoid lung nodules are the most common pulmonary manifestations of RA. Rheumatoid nodules in mediastinal lymph nodes are extremely uncommon. We describe a male patient with long-standing RA and subcutaneous rheumatoid nodules presenting with multiple lung nodules and mediastinal lymphadenopathies. Definite histopathology of a lymph node was consistent with necrobiotic granuloma due to RA.

    A rare complication of acute or chronic pancreatitis is the formation of a mediastinal pancreatic pseudocyst (MPP), which is caused by tracking of pancreatic fluids through anatomical openings of the diaphragm into the mediastinum. Herein, we report the imaging characteristics of three cases of this condition. Our results revealed three features in common: (i) the connection between the mediastinum and the pancreatic cystic lesion; (ii) the presence of pleural effusions; and (iii) imaging findings consistent with chronic pancreatitis, such as pancreatic atrophy and calcifications and dilatation and/or stricture of main pancreatic duct (MPD).

We herein report a case of multiple HCs of the mediastinum and liver in a - 50 year-old woman presented with chest pain, cough and dyspnea for about two years. She had been treated for tuberculosis for 20 years. Chest CT scan showed multiple cysts in posterior mediastinum and one cyst in left lobe of liver. Via right posterolateral thoracotomy, multiple cysts were excised in mediastinum. And then, hepatic left lobe cyst was removed trans-diaphragmatically. Histopathologic examination confirmed HCs.

The patient reported a 6-month history of chest pain with increasing dyspnea for 2 months. Enhanced computed tomography revealed a 10×16-cm mass in the posterior mediastinum. Other physical examinations were normal. Radical resection was performed under the agreement of patient. Subsequent pathological analysis indicated a liposarcoma. The patient recovered and was successfully discharged. However, at a follow-up examination 12 months after surgery, recurrence was identified in the anterior mediastinum. Therefore, the patient underwent surgery. The postoperative course was uneventful, however, there was evidence of disease recurrence 2 years after the second surgery. The patient refused any treatment and succumbed after 3 months. PMID:27313694

    Anterior neck masses in young children can be a diagnostic challenge for otolaryngologists and radiologists. We present a rare case of herniation of normal mediastinal thymus in a four-year-old girl. Additional medical features as an inguinal hernia and trochlear nerve paresis raised the question whether there is a causal relationship or an association. A connective tissue disorder could not be diagnosed as possible causal factor to the abnormal movement of the mediastinal thymus. Awareness and recognition of this benign phenomenon is important in order to avoid unnecessary biopsy or surgery. Diagnosis can be confirmed by ultrasonography. Magnetic Resonance Imaging might be valuable in order to obtain more information about the extension of the mass. PMID:26968057

    Klinefelter syndrome (KS) is a well-documented abnormality of the sex chromosome, with an incidence of 1 in 600 newborn males. It is characterized by a 47, XXY or a mosaic karyotype, hypergonadotrophic hypogonadism, infertility, reduced body hair, gynecomastia, and tall stature. Different neoplasms such as breast, testicular, and lymphoreticular malignancies may occur in 1% to 2% of the cases with KS. Herein we describe a case of mediastinal mixed germ cell tumor (GCT) in a 40-year-old male with KS. Interestingly, this case also had mitral valve prolapse, and an incidental papillary microcarcinoma of the thyroid gland. In view of the presence of pulmonary nodules, antemortem differential diagnoses considered were mycobacterial infection, lymphoma, thymic carcinoma, and a primary/metastatic neoplasm of the lung. As GCT was not considered, the serum markers of a GCT were not performed. The diagnosis of this rare mediastinal mixed GCT with KS was made at autopsy. PMID:26881632

    2015-01-01

    Video-assisted thoracoscopic surgery (VATS) lobectomy is safe, oncologically effective, and increasingly utilized for lung cancer resection. Lessons from VATS lobectomy experience can guide the use of a VATS approach to resect mediastinal masses. Exposure and dissection when using VATS to resect anterior mediastinal masses has unique challenges. Several maneuvers acquired from experience with VATS lobectomy can reduce the technical difficulty and often prevent conversion to an open approach. In this troubleshooting guide, we offer ‘tips’ to both avoid and manage numerous intra-operative technical difficulties that commonly arise during VATS anterior mediastinal procedures. Avoiding an open approach may improve outcomes, although conversion for safety or complete resection can be necessary. Techniques and experiences derived from VATS lobectomy can facilitate VATS resection of mediastinal masses. PMID:26693151

    Autoinflammatory diseases are caused by inflammasome dysregulation leading to overproduction of proinflammatory cytokines and a pathological delay in the inflammation switching off. The progress of cellular biology has partially clarified pathogenic mechanisms behind monogenic autoinflammatory diseases, whereas little is known about the polygenic ones. Although the genetic susceptibility of periodic fever, aphthous stomatitis, pharyngitis, and adenopathy (PFAPA) syndrome is still obscure, the presence of overlapping symptoms with monogenic periodic fevers, the recurrence in family members, the important role played by dysregulated interleukin- (IL-) 1β secretion during flares, the overexpression of inflammasome-associated genes during attacks, and, last but not least, the therapeutic efficacy of IL-1β blockade strongly indicate a potential genetic involvement in its pathogenesis, probably linked with environmental factors. PFAPA syndrome has a typical inception in the pediatric age, but a delayed onset during adulthood has been described as well. Treatments required as well as effectiveness of tonsillectomy remain controversial, even if the disease seems to have a self-limited course mostly in children. The purpose of this review is to provide an overview of this complex polygenic/multifactorial autoinflammatory disorder in which the innate immune system undoubtedly plays a basic role.

    Primary malignant mediastinal teratoma is a rare tumour previously regarded as inevitably fatal. In a series of eight male patients with a mean age of 24 years five remain alive and well. All patients showed raised serum concentrations of human chorionic gonadotrophin or alpha fetoprotein. The patients were treated with intermittent combination chemotherapy that included cisplatin.

    Primary malignant mediastinal teratoma is a rare tumour previously regarded as inevitably fatal. In a series of eight male patients with a mean age of 24 years five remain alive and well. All patients showed raised serum concentrations of human chorionic gonadotrophin or alpha fetoprotein. The patients were treated with intermittent combination chemotherapy that included cisplatin.

    Abstract Germ cell tumors (GCTs) represent a well-recognized group of heterogeneous neoplasms with diverse clinical, histopathological, diagnostic, and prognostic characteristics. We present a rare case of a locally aggressive, chemotherapy-resistant immature mediastinal teratoma with a peculiar histological finding of a multilineage somatic-type malignant degeneration. A 21-year-old male patient presented with a 3-week history of persistent, blood-tinged productive cough and shortness of breath. A contrast-enhanced computed tomography (CT) scan of the chest showed a heterogeneous mass occupying the right hemithorax and abutting on adjacent structures. CT-guided biopsy was consistent with immature teratoma. Combination chemotherapy with bleomycin, etoposide, and cisplatin was initiated, albeit without success; the mass showed interval progression in size, and surgical resection through clamshell incision was performed. Histological assessment of the resected mass confirmed the diagnosis of immature teratoma and revealed an extensive multilineage malignant differentiation into sarcomatous, carcinomatous, and melanomatous components. The patient underwent an uneventful recovery but presented 2 months later with extensive liver and bone melanomatous metastases. In this report, relevant findings from the literature are also highlighted. Despite being exceptionally rare, such tumors carry poor prognosis. Understanding the clinicopathological characteristics and biological behavior of such tumors may provide an insight into interventions tailored to improve the otherwise dismal disease outlook.

    A 65 year old female patient suffering from multinodular goitre and from hypercalcaemic syndrome which had been and was being treated with drugs for a number of years. The patient undergoes total thyroidectomy. Surgical neck and anterior mediastinum exploration was negative for sick parathyroids. Neck and chest TC and 'TC sestamibi scintigraphy showed the presence of a 7 cm hyperfunctional ectopic parathyroid tissue in the postero-superior mediastinum infiltrating oesophagus. Video bronchoscopy revealed an extrinsic compression of the trachea. The patient underwent surgery. Through right postero-lateral thoracotomy and mediastinal pleura incision, the adenoma excision was carried out. The histological examination revealed a potentially malignant parathyroid adenoma with infiltration, without over-reaching the capsule. The surgical treatment resulted in an immediate resolution of the clinical symptomatology. One year later, the follow up was shown no observable relapse with normal calcium and PTH values. Today, the tendency to minimally invasive surgery, an accurate preoperative localization of the adenoma and the use of techniques such as intra-surgical nuclear mapping through manual gamma probes, selective angiography, venous intraoperative dosage of PTH and intra-surgical ultrasound scan.

    The thoracolumbar spinal cord receives its blood supply primarily from the artery of Adamkiewicz (AA), a branch of thoracolumbar intercostal arteries. Aortic cross-clamping during operation for descending aortic aneurysms can cause paraplegia due to spinal cord ischemia secondary to low blood flow through the AA. A 69-year-old woman was diagnosed with a left posterior mediastinal tumor measuring 66 mm. The tumor was adjacent to the thoracic aorta between Th10 to Th12 vertebral levels. Preoperative 3-dimensional computed tomography (3D-CT) imaging revealed 2 AAs originated from the 10th and 11th left intercostal arteries just near the tumor. The patient underwent a left thoracotomy and the 2 intercostal arteries were carefully dissected from the encapsulated tumor. Complete resection was safely achieved with preservation of the AAs. Pathology revealed a schwannoma. There were no complications. In performing thoracic surgery for posterior mediastinal tumors, it is important to identify the AAs preoperatively and preserve them.

    We report the case of a 77-year-old woman with mediastinal lymph node metastasis of combined hepatocellular and cholangiocarcinoma who was successfully treated with S8 segmentectomy and lymphadenectomy. A hepatic nodule was detected in segment 8 during follow-up computed tomography (CT) after left iliac arterial aneurysm repair. The patient was diagnosed with a hepatocellular carcinoma (HCC), and transcatheter arterial chemoembolization (TACE) was selected for HCC because of the patient's condition. The levels of tumor markers did not change after TACE was performed twice. Therefore, TACE treatment was considered to be ineffective for HCC, and the patient was admitted to our hospital for surgical resection. In addition to the primary lesion, a lymph node with a diameter of 20 mm was detected in the anterior mediastinum using CT and magnetic resonance imaging(MRI). We did not find any other metastases, and therefore, S8 segmentectomy and lymphadenectomy in the anterior mediastinum were performed. Recovery was uneventful, and the patient was discharged from the hospital on postoperative day 12. Based on histopathologic findings, combined hepatocellular and cholangiocarcinoma with mediastinal lymph node metastasis was confirmed. Levels of tumor markers normalized, and the patient survived without recurrence for 6 months. PMID:26805196

    Introduction: Precise mediastinal lymph node staging in patients with non-small cell lung carcinoma (NSCLC) provides important prognostic information and it is obligatory in treatment strategy planning. 18Fluoro-deoxy-glucose (18F-FDG) positron emission tomography - computerized tomography (PET-CT) based on detection of metabolic activity showed superiority in preoperative staging of lung carcinoma. Materials and Methods: Total number of 26 patients diagnosed with NSCLC were included in this retrospective, cross-sectional study. Status of mediastinal lymph nodes was assessed in all patients comparing contrast enhanced CT and 18F-FDG PET-CT findings. Discussion: We found in our study that 50% of patients had different N stage on contrast enhanced CT comparing to 18F-FDG PET-CT findings. Among the total number of patients which had different nodal status on PET-CT comparing to CT alone, we found in our study that 54% of patients had change in further therapy protocol after PET-CT change of nodal stage. Conclusion: Combined PET-CT which offers advantages of both modalities is excellent method for nodal (N) staging, so it is recommended in initial staging in patients with NSCLC. PET-CT used preopratively for mediastinal nodal staging has significant impact on further therapy planning and also has an consequential impact on health system savings. PMID:27147799

    Summary Aims Deep neck infections are rare but potentially fatal complication of pulpal abscess of the teeth. If an infection can progress rapidly from a toothache to a life threatening infection, then it is critical that dentists be able to recognize the danger signs and identify the patients who are at risk. Mediastinitis is a severe inflammatory process involving the connective tissues that fills the intracellular spaces and surrounds the organs in the middle of the chest. This pathology has both an acute and a chronic form and, in most cases, it has an infectious etiology. This study want to expose the experience acquired in the Oral and Maxillo-facial Sciences Department, Policlinico Umberto I, “Sapienza” University of Rome, regarding two clinical cases of disseminated necrotizing mediastinitis starting from an odontogenic abscess. Methods We report two clinical cases of disseminated necrotic mediastinitis with two different medical and surgical approaches. The radiographic and photographic documentation of the patients was collected in the pre-and post-operatively. All patients underwent a CT scan and MRI. Results Mediastinitis can result from a serious odontogenic abscess, and the extent of its inflammation process must be never underestimated. Dental surgeons play a key role as a correct diagnosis can prevent further increasing of the inflammation process. Conclusions A late diagnosis and an inadequate draining represent the major causes of the elevated mortality rate of disseminated necrotizing mediastinitis. PMID:26330907

    Background To present the technique of single-port video-assisted thoracoscopic mediastinal tumor resection, which includes limited thymectomy, extended thymectomy, cyst excision and posterior mediastinal tumor excision, and the early results of resection with the use of this technique. Methods Forty patients with mediastinal tumors were treated with single-port thoracoscopic mediastinal resection at Chang Gung Memorial Hospital between April 2014 and September 2015. The surgical intervention was performed through the fourth or fifth intercostal space at the anterior axillary line. A 5 or 10 mm 30 degree video camera and working instruments were employed simultaneously at this incision site throughout the surgery. Results Among the 40 cases included in the final analysis, 10 extended thymectomies, 7 limited thymectomies, nine cyst excisions and 14 tumor excisions were performed successfully without the need for conversion. For the 40 patients who underwent single-port video-assisted thoracoscopic surgery (VATS), the mean operation time was 97.3±31.2 min and the average blood loss was 29.75±39.77 mL. The average length of the incision wound was 3.22±0.79 cm and the average length of postoperative hospital stay was 3.72±1.63 days. There were no mortalities and mobility was achieved within 30 days postoperatively. Conclusions Our preliminary report suggests that uniportal VATS for mediastinal tumor resection is a promising and safe technique within a short-term period. PMID:27134836

    Primary cranial mediastinal hemangiosarcomas are uncommon tumors. A 30-kg, 2-year-old, intact female German shepherd was presented for evaluation of cachexia and respiratory distress of a few days’ duration. Lateral radiographic projection of the thorax revealed significant pleural effusion. Computed tomography revealed a cranial mediastinal mass effect adjacent to the heart. On surgical exploration, a pedunculated mass attached to the esophagus, trachea, brachiocephalic trunk, left subclavian artery and cranial vena cava without attachment to the right atrium and auricular appendage was removed and debrided by use of blunt dissection and dry gauzes, respectively. Histopathology results described the cranial mediastinal mass as hemangiosarcoma. At 8 months and 5 days post-operatively, the patient died. Primary cranial mediastinal hemangiosarcomas, although a seemingly rare cause of thoracic pathology in young dogs, should be considered in the differential diagnosis for pleural effusion and soft tissue mass effect in the cranial mediastinum. This is the first case report in a dog to describe primary cranial mediastinal hemangiosarcoma. PMID:25089185

    We report a case of potentially fatal cervical necrotizing fasciitis and descending necrotizing mediastinitis due to deep neck infection in a 66-year-old male patient with no history or evidence of immunocompromising disorders. On admission, he had painful neck movements and the skin over his neck was red, hot and tender. A computerized tomography (CT) scan of his neck and chest showed evidence of air collection in soft tissues. He was treated with broad-spectrum intravenous antibiotics and early massive cervical drainage. Prompt diagnosis by CT of the neck and chest enabled an early surgical treatment of cervical necrotizing fasciitis. Although acute mediastinitis is a fatal infection involving the connective tissues that fill the interpleural spaces and surround the median thoracic organs, an extensive cervicotomy combined with appropriate antibiotics can prevent the need for mediastinal drainage.

    Anastomoses often leak after esophageal surgery; if they are not detected in time, leaks can give rise to complications like fluid collections, superinfections, and mediastinitis. Although these complications usually require surgical treatment, different series of patients successfully treated with conservative or minimally invasive approaches have been reported. We present the case of a patient who developed a mediastinal abscess after epiphrenic diverticulectomy. We treated the abscess with US-guided percutaneous transhepatic drainage to avoid surgical reintervention. Although other cases of a transhepatic approach to thoracic lesions have been reported, to our knowledge this is the first report of this technique in mediastinal abscesses. We recommend that transhepatic drainage be considered a therapeutic option in the management of these complications. PMID:22464798

    Abstract Objective To highlight the 2015 Canadian Hypertension Education Program (CHEP) recommendations for the diagnosis and assessment of hypertension. Quality of evidence A systematic search was performed current to August 2014 by a Cochrane Collaboration librarian using the MEDLINE and PubMed databases. The search results were critically appraised by the CHEP subcommittee on blood pressure (BP) measurement and diagnosis, and evidence-based recommendations were presented to the CHEP Central Review Committee for independent review and grading. Finally, the findings and recommendations were presented to the Recommendations Task Force for discussion, debate, approval, and voting. The main recommendations are based on level II evidence. Main message Based on the most recent evidence, CHEP has made 4 recommendations in 2 broad categories for 2015 to improve BP measurement and the way hypertension is diagnosed. A strong recommendation is made to use electronic BP measurement in the office setting to replace auscultatory BP measurement. For patients with elevated office readings, CHEP is recommending early use of out-of-office BP measurement, preferably ambulatory BP measurement, in order to identify early in the process those patients with white-coat hypertension. Conclusion Improvements in diagnostic accuracy are critical to optimizing hypertension management in Canada. The annual updates provided by CHEP ensure that practitioners have up-to-date evidence-based information to inform practice. PMID:26564654

    Minimally invasive surgery has changed the way operative procedures are performed in many specialties. As surgeons have become progressively facile with these techniques, the opportunities to use them have expanded. In thoracic surgery, many surgeons now use minimally invasive techniques to resect small, uncomplicated pathologies of the mediastinum as well as to perform thymectomy for myasthenia gravis. Experience with these techniques has allowed new knowledge to be gained and expansion of the use of these techniques for more complicated mediastinal pathology. This keynote address will outline the instrumentation and techniques that we have adopted over a decade of using these techniques for more complicated mediastinal pathology. PMID:26693146

    Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has changed the way mediastinal staging is performed in lung cancer patients. EBUS-TBNA is probably the most important non-invasive procedure for mediastinal staging and the currently preferred approach in many reference cancer centres worldwide. EBUS-TBNA is a less invasive technique than mediastinoscopy with low morbidity and no mortality and can be performed in an outpatient setting with excellent results. This study describes the technical aspects of EBUS-TBNA and our personal experience with the procedure. PMID:25332380

    Background: Transesophageal echocardiography (TEE) is a well-established method for detecting and diagnosing heart tumors. In contrast, its role in assessing the presence, growth and evidence of malignant tumors originating from mediastinal sites remains unclear. The aim of this study was to compare the diagnostic impact of TEE and transthoracic echocardiography (TTE) for determining the localization, growth and malignancy of adult mediastinal tumors (MTs). Methods: In a prospective and investigator-blinded study, we evaluated 144 consecutive patients with MT lesions to assess the diagnostic impact of TEE and TTE for detecting the presence of tumors spreading both inside and outside of the heart and for determining infiltration and invasion using pathological examination results as a reference. Results: All tumor lesions were diagnosed and carefully evaluated by biopsy. Biopsy revealed malignant tumors in 79 patients and benign tumors in 65 patients. When compared to histological findings, TEE predicted malignancy from the presence of tumors spreading both inside and outside of the heart and from infiltration and invasion in 49/79 patients (62.0%). TTE predicted malignancy in only 8/79 patients (10.1%, P < 0.005). TEE visualized tumor lesions in 130 patients (90.3%) while the TTE visualized tumor lesions in 110 patients (76.4%) and was less effective at detecting MT lesions (P < 0.001). TTE and TEE could detect anterior MTs and adequately verified MTs (P > 0.05); TEE detected medium MTs better than TTE (P < 0.001). Conclusions: TEE is effective and superior to TTE for predicting the localization and growth of MTs as well as for accessing evidence of tumor malignancy. TTE and TEE were able to detect anterior MTs; TEE was able to detect medium MT better than TTE. PMID:25881598

    The mediastinum may be divided into 4 zones divided by the tracheo-bronchial axis in which are situated the lymphatic chains involved in the lymphatic drainage of the lungs. In the upper right zone there are 2 chains which are frequently involved, the right paratracheal chain (PTD) and the tracho-oesophageal chain (TO) and 2 lymphatic chains which are less often involved, the superior right phrenic chain (PH Dt) and the lymphatic chain which crosses the Azygos vein (AZM). In the superior left zone are found 2 chains which are frequently infiltrated: The pre-aortic carotid chain (AO) and the left superior bronchial chain (BSG) and 2 chains which are more rarely involved: The left superior phrenic (PHG) and the chain which crosses the aorta (the minor aorta Azygos; AOmi). At the level of the right and left inferior zones are found important groups of lymphatic ganglia at the intratracheo-bronchial bifurcation (ITB) and of one other part of the tracheo-oesophageal axis, the juxta-oesophageal ganglia (OE) and those of the triangular ligament (LT). The lymph coming from the pulmonary segments crosses the ganglia (LN) of the segments of the lobe and of the hilum before reaching the mediastinum and then at the final stage the lymph nodes situated on the margins of the mediastinum considered as N3 in cancer assessment. This schema is not the rule. In less than 5% of cases the lymph may drain without any lymph node relay either to the subclavicular hollow or to the thoracic duct in the mediastinum. More frequently (in 20-35% cases according to the segment considered) the lymph returns directly to the mediastinum ganglia without relaying through the intrapulmonary ganglia. Finally there are those cases where only the perilobar LN are involved. In these cases it is not necessarily the LN of the lobe drained but sometimes of another pulmonary lobe. These direct paths (N2) confirmed in study of cancer, demand and justify the need for a systematic cure of mediastinal LN. It is

    BACKGROUND Invasive candidiasis is a potential problem for patients receiving long-term immunosuppressive treatment. Psoriatic arthritis is one of many chronic diseases that can be successfully treated with immunosuppressive drugs, in spite of a documented and accepted risk for infectious complications. Critical awareness of possible infection must be part of the surveillance of such patients. CASE REPORT This is the case of a 68-year-old Norwegian male, treated with long-term immunosuppression for psoriatic arthritis, hospitalized with acute subcutaneous and mediastinal emphysema of unknown cause. He died of acute respiratory failure with circulatory collapse shortly after admission. The autopsy revealed mediastinal and subcutaneous emphysema and a mediastinal abscess containing Candida with probable entrance from the esophagus. CONCLUSIONS We consider invasive candidiasis of the esophagus to be the cause of both the chronic abscess and the acute mediastinal emphysema. This case illustrates the importance of awareness of invasive candidiasis as a possible complication in a patient with long-term immunosuppression. PMID:27389822

    Mediastinal goiter is a well known benign disease, usually resectable through a cervical approach with minimal morbidity and mortality. Only occasionally a median sternotomy or a lateral thoracotomy may be required. The present case is worthy of presentation because of the exceptional dimension of the disease and the surgical challenge that it presented. In a 72-year-old woman a large intrathoracic goiter of the right thorax caused a severe dyspnoea due to an important contralateral mediastinal shift with compression of the lung, superior vena cava system and trachea. At surgical exploration, through a cervico-sternotomic approach, the mediastinal structures dislocation and the strong adherences between the anomalous neovascularized capsula of the mass and the surrounding structures, complicated the surgical dissection. An accidental lesion of the innominate artery required its reimplantation on the ascending aorta. An immense mass, was finally removed and pathological examination revealed a rare case of neovascularized, pseudosarcomatoid capsula among a benign hyperplastic proliferation. In spite of its benign nature, a giant goiter caused a life-threatening compression of the respiratory tract and lung parenchyma in this patient. The dimension of the lesions, the mediastinal anatomy alterations and the severe intraoperative haemorrhage represented major technical difficulties during surgical resection. PMID:11501515

    Ultrasound imaging has gained importance in pulmonary medicine over the last decades including conventional transcutaneous ultrasound (TUS), endoscopic ultrasound (EUS), and endobronchial ultrasound (EBUS). Mediastinal lymph node (MLN) staging affects the management of patients with both operable and inoperable lung cancer (e.g., surgery vs. combined chemoradiation therapy). Tissue sampling is often indicated for accurate nodal staging. Recent international lung cancer staging guidelines clearly state that endosonography should be the initial tissue sampling test over surgical staging. Mediastinal nodes can be sampled from the airways [endobronchial ultrasound combined with transbronchial needle aspiration (EBUS-TBNA)] or the esophagus [endoscopic ultrasound fine needle aspiration (EUS-FNA)]. EBUS and EUS have a complementary diagnostic yield and in combination virtually all MLNs can be biopsied. Additionally endosonography has an excellent yield in assessing granulomas in patients suspected of sarcoidosis. The aim of this review in two integrative parts is to discuss the current role and future perspectives of all ultrasound techniques available for the evaluation of mediastinal lymphadenopathy and mediastinal staging of lung cancer. A specific emphasis will be on learning mediastinal endosonography. Part 1 deals with an introduction into ultrasound techniques, MLN anatomy and diagnostic reach of ultrasound techniques and part 2 with the clinical work up of neoplastic and inflammatory mediastinal lymphadenopathy using ultrasound techniques and how to learn mediastinal endosonography.

    Usually slow-growing and benign, mature mediastinal teratomas are rare clinical entities. They may be complicated by rupture into the pleural or pericardial spaces, lungs, or bronchi. Complete surgical resection is the treatment of choice and is usually curative. We report the unusual case of a 24-year-old woman presenting 15 weeks postpartum with a huge ruptured mature mediastinal teratoma superinfected with Mycobacterium avium Catastrophic bleeding from the superior vena cava was encountered on mobilization of adhesions attached to it, requiring extracorporeal membrane oxygenator support for control. Histopathological examination confirmed a 12.0 × 7.8 × 4.5-cm differentiated teratoma without malignant transformation. PMID:27440933

    This case report illustrates successful Video Assisted Thoracic Surgery (VATS) performed on a 45-year-old woman and 52-year-old man presenting with a mass in left and right paravertebral space on the CT scan respectively. VATS has many benefits over traditional open operation (thoracotomy), resulting in less pain and shorten recovery time. However, VATS has higher equipment cost but when an experienced surgeon performs the surgery, better outcomes are achieved. VATS is not common in Pakistan's surgical setup as it is an expensive method of eradicating mediastinal pathologies and not every patient undergoes VATS. The primary objective of presenting these cases is to promote the use of VATS specifically for removal of posterior mediastinal tumors and improve the surgical outcomes. PMID:26208561

    Acute mediastinitis is a life-threatening complication (20 to 40 % of mortality) secondary to oropharyngeal abscesses, neck infections or oesophageal leak spreading into the mediastium. Early diagnosis and optimal therapeutic approach are crucial for patient survival. CT scanning of the cervical and thoracic area is a useful tool for diagnosis and follow-up. Treatment is based on broad-spectrum antibiotherapy, adequate surgery, mediastinal drainage, and treatment of possible organ failure. There is no surgical standardized attitude. Mini-invasive approach could be satisfactory when prompt diagnosis is established and the thoracic drainage is effective. Repeated postoperative CT scanning and close clinical and laboratory monitoring could make an additional thoracotomy a second-line procedure. PMID:20207299

    Esophageal perforation is a very rare occurrence because accidental swallowing of foreign bodies is uncommon in adults. Thus, perforation due to swallowing of a foreign body and subsequent development of mediastinitis is rarely encountered by physicians. We experienced such a case and described an adult male patient who had perforated esophagus after accidentally swallowing a mussel shell. The patient visited our emergency department complaining of painful dysphagia for 4 days. A review of history revealed that he consumed a spicy seafood noodle soup containing mussel shells 4 days ago. Computed tomography (CT) of the chest showed the foreign body in the esophagus and pneumomediastinum was identified. We removed the mussel shell fragment using rigid esophagoscopy; explo-thoracotomy, debridement of mediastinal abscess and irrigation were performed.

    Computed tomography (CT) of the chest is a very common staging investigation for the assessment of mediastinal, hilar, and intrapulmonary lymph nodes in the context of lung cancer. In the current clinical workflow, the detection and assessment of lymph nodes is usually performed manually, which can be error-prone and timeconsuming. We therefore propose a method for the automatic detection of mediastinal, hilar, and intrapulmonary lymph node candidates in contrast-enhanced chest CT. Based on the segmentation of important mediastinal anatomy (bronchial tree, aortic arch) and making use of anatomical knowledge, we utilize Hessian eigenvalues to detect lymph node candidates. As lymph nodes can be characterized as blob-like structures of varying size and shape within a specific intensity interval, we can utilize these characteristics to reduce the number of false positive candidates significantly. We applied our method to 5 cases suspected to have lung cancer. The processing time of our algorithm did not exceed 6 minutes, and we achieved an average sensitivity of 82.1% and an average precision of 13.3%.

    In order to assess the significance of large mediastinal masses in patients with Hodgkin's disease, we analyzed all patients with pathological stage (PS) IA or IIA disease evaluated and treated at Yale between 1969 and 1978. There were 131 such patients treated initially with radical radiotherapy only, combination chemotherapy being reserved for those who failed radiation. Actuarial 5 and 10 year survivals were 95%. The presence of a mediastinal mass regardless of size did not affect survival. Relapse-free survival was 77% at 5 years, 74% at 10 years in the entire group. Patients with any mediastinal involvement had a 65% relapse-free survival, 72% if the mass was < 33% of transverse chest diameter, 55% if the mass was > 33%. These differences are suggestive of a greater tendency of such patients to fail radiotherapy but the differences were not statistically significant. Patients who did fail radiotherapy were for the most part successfully retreated with combined modality therapy (chemotherapy and radiation), accounting for the most part successfully retreated with combined modality therapy (chemotherapy and radiation), accounting for the overall survival of 95%. Only 6 patients died of causes related to Hodgkin's disease and 2 of these deaths were related to combined modality therapy complications. Because of the serious potential long term consequences of combined modality treatment, it should be used with great caution and on an individual basis only in PSIA and IIA patients.

    We describe a 72-year-old patient with mediastinitis caused by Methicillin-resistant Staphylococcus aureus (MRSA) and Candida albicans after median sternotomy who was successfully treated with wound closure with pectoral musculocutaneous flap and closed continuous mediastinal irrigation. The irrigation device consisted of two pairs of irrigation and suction tubes which placed upper and lower half of mediastinum respectively, in which high rate irrigation technique (200 ml/h) was employed using 0.01% of Vancomycin hydrochloride as a base agent and additional 0.1% of Povidone-iodine in early phase and 0.01% of Fluconazole in late phase. After 12-days irrigation, the drainage culture turned negative and the wound was healed and tomographically granulated. High rate irrigation with sufficient concentration of antimicrobial agents selected according to each organism sensitivity could eliminate redundant irrigation and contribute to avoid antimicrobial toxication. We experienced also another four cases (two caused by MRSA, two caused by Serratia liquefaciens) treated successfully with this technique. These results led us to believe that continuous mediastinal irrigation technique could be carried out with safe and effectiveness so far as high rate irrigation with low concentration of Povidone-iodine is employed.

We report a case of thymic carcinoma diagnosed by using EUS elastography with strain ratio and fine-needle aspiration (FNA). A 64-year-old woman presented with altered mental status and was diagnosed with autoimmune encephalitis. Further work-up suggested a superior mediastinal mass, for which she underwent EUS. A hypoechoic mass was found in the superior mediastinum at the level of the aortic arch. Real-time EUS elastography showed a predominantly blue hue to the mass concerning for malignancy. FNA of the mass was performed, which revealed numerous large neoplastic cells under a background of a small lymphoid infiltrate. Immunohistochemistry was strongly positive for PAX8, pancytokeratin, and CAM5.2. The pathologic and immunohistochemical stains were consistent with thymic carcinoma. PMID:27386480

    Objectives To evaluate the impact of pulmonary emphysema (PE) on the incidence and severity of radiation pneumonitis (RP) in patients with lung and mediastinal tumours. Methods 92 patients were enrolled. Involved-field radiation therapy (non-small cell carcinoma or mediastinal tumours in 69 patients; median 70 Gy) and accelerated hyperfractionation (limited disease small cell carcinoma in 23 patients; median 45 Gy) were performed. Common Terminology Criteria for Adverse Events v.3.0 was used to evaluate RP and the relationship with the percentage of pulmonary volume irradiated to >20 Gy (V20) and PE. PE was diagnosed by the presence of low-attenuation areas (LAAs) on CT scans and was classified into Grades 0–4 according to the extent of the LAAs. Results The median follow-up time was 16 months. The 6-month cumulative incidence of RP at Grade 3 or greater was 7.7% and 34.1% in patients with a V20 of <25% and ≥25%, respectively (p=0.017). In patients with PE Grades 0, 1, 2 and 3 or greater, the incidence of RP was 16.5%, 9.1%, 8.6% and 54.0%, respectively. As the PE Grade increased, the incidence of RP also increased significantly. Conclusion The incidence and severity of RP are significantly higher in patients with a high V20 value as well as in those with severe PE. PMID:21385918

    A review of staging investigations in the preoperative evaluation of mediastinal involvement in primary bronchial carcinoma is presented. The following conclusions are offered as guidelines for the use of mediastinal staging procedures in clinical practice: Surgical staging methods have the over-riding advantage of superior specificity over indirect imaging techniques. Where 67Ga-imaging or CT scanning are not available, routine pre-operative mediastinoscopy or, when appropriate, mediastinotomy will identify most patients with non-resectable disease but this approach entails a high proportion of true negative examinations. Radioisotope ventilation and perfusion lung imaging has no place in the pre-operative staging of lung cancer. Where the techniques are available, 67Ga-imaging and CT scanning have a use in selecting patients for mediastinal exploration. A negative mediastinal 67Ga scan or a negative CT examination suggest that mediastinal exploration will be unrewarding in the vast majority of cases and may be omitted prior to thoracotomy. A positive mediastinal 67Ga scan or the demonstration of abnormal mediastinal nodes by CT is an indication for mediastinal exploration which, if negative should be followed by thoracotomy.

    Descending necrotizing mediastinitis is believed to be a rare and serious complication of odontogenic and oropharyngeal infections. It is associated with a high (up to 40%) mortality rate, which can be attributed to delays in diagnosis and inadequate surgical drainage. Between May 1999 and September 2002, we treated 7 cases at our institution in New Delhi, indicating that such fulminating infections are not so rare in developing countries. In our 7 cases, a high index of suspicion and early computed tomography helped us make a rapid diagnosis and initiate prompt treatment, which resulted in a favorable outcome in 6 cases (mortality rate: 14.3%).

    Neuroblastoma is an embryonal tumour that evolves from the neural crest cell. This neoplasm may arise at any site in the sympathetic nervous system, including the brain, the cervical region, the posterior mediastinum, the para-aortic sympathetic ganglia, the pelvis, and the adrenal medulla. The clinical presentation in neonatal age is rare and the differential diagnosis includes congenital lung malformations, pneumoniae, atelectasia, etc. The case of a newborn with a mediastinal neuroblastoma is presented. This case illustrates how a patient with an X-ray image compatible with a thoracic tumor should be studied. PMID:16381510

    Extramedullary plasmocytoma (EMP) is a rare cell neoplasm most frequently localised in the upper respiratory tract. We report the case of a 43 year-old-man, with an unusual presentation of EMP developing in the mediastinum, two years after a diagnosis of solitary plasmocytoma of the bone which was successfully treated by local irradiation. In this aggressive presentation, we decided to perform an autologous hematopoietic stem cell transplantation. Two months after transplantation, CT scan showed disappearance of the mediastinal mass and immunofixation of the serum was normal. Selected cases of diffuse EMP, could benefit from intensive treatment followed by autologous hematopoietic stem cell transplantation. PMID:14534964

    A 17-year-old boy developed prominent mediastinal and subcutaneous emphysema while receiving treatment with 5-aminosalicylic acid (5-ASA) and oral corticosteroids for severe ulcerative colitis. We ruled out infection and initiated oral administration of tacrolimus, after which both the underlying disease and mediastinal and subcutaneous emphysema improved. However, he continued to experience repeated bouts of ulcerative colitis, so we ultimately opted for surgical intervention. Although mediastinal and subcutaneous emphysema is rare, it is one of the known extra-intestinal complications and can be particularly concerning. In this patient, mediastinal and subcutaneous emphysema might have been caused by the vulnerability of pulmonary alveolar walls to steroid medication and the increase of pulmonary alveolar pressure with abdominal pain and breath holding. Here, we report a case of inflammatory bowel disease with mediastinal and subcutaneous emphysema, along with a review of the literature. PMID:26947047

    Primary mediastinal large B-cell lymphoma (PMLBL) is an uncommon non-Hodgkin lymphoma with a distinct clinicopathological entity in the WHO classification of lymphoid malignancies. It is known to originate from B-cells of the thymus. It mimics thymic neoplasms and other lymphomas clinically and histopathologically. We reported a 33-year-old obese man who presented with shortness of breath off and on for 4 years. Radiologically, there was a huge anterior mediastinal mass. Tru-cut biopsy was initially diagnosed as type-A thymoma. Histopathological examination of the excised specimen revealed PMLBL with stromal fibrosis and sclerosis which created a diagnostic difficulty. The neoplastic cells varied from medium-sized to large pleomorphic cells, including mononuclear cells with centroblastic and immunoblastic features as well as bi-lobed Reed Sternberg (RS)-like cells and horse-shoe like hallmark cells. Some interlacing spindle cells and epithelioid cells were also present. Immunohistochemically, tumour cells expressed diffuse positivity for LCA, CD20, CD79a, CD23, Bcl2, MUM-1 and heterogenous positivity for CD30 and EMA, and were negative for CD10, CD15 and ALK. Ki67 scoring was very high. Tumour cells infiltrated into peri-thymic fat and pericardium. No malignant cells were detected in the pleural fluid and there was no bone marrow infiltration. The patient showed partial response to 6 cycles of RICE chemotherapy, and was planned for second line chemotherapy using hyper-CVAD regimen followed by autologous stem cell transplantation. This case illustrates the importance of thorough sampling and immunohistochemistry in differentiating PMLBL from its differential diagnoses. PMID:27568673

    T-cell lymphoblastic lymphoma is an aggressive malignancy that represents 85% of all lymphoblastic lymphomas. It usually occurs in late childhood, adolescence and young adulthood with a 2:1 male preponderance and it presents with pleural effusion and respiratory symptoms and in rare cases vena cava syndrome can be encountered. We present the case of a 13-year-old patient who was referred to our clinic from a local hospital where he was diagnosed with a mediastinal tumor. The patient presented with thoracic pain, fever, coughing and fatigability for a month prior to admission, after having underwent surgery for abdominal pain (appendectomy). On admission to our hospital, a thoracic computed tomography (CT) scan was performed and showed the presence of an anterior mediastinal mass measuring 109/76/140 mm, well defined, which came in close contact with the superior vena cava, the ascending aorta and the pulmonary artery, right pleural effusion and a collapsed lung on the right side. The decision was taken to perform a tumor biopsy and a right pleural drain was placed. The patient's post-operative evolution was favorable with the remission of the respiratory symptoms. The histopathological result showed the presence of T-cell lymphoblastic lymphoma and the patient was then transferred to the oncology ward where he underwent chemotherapeutic treatment, with a favorable outcome. T-cell lymphoblastic lymphoma is an aggressive type of lymphoma and it is usually hard to diagnose considering the fact that the symptoms are often vague. It is essential to establish the diagnosis without delay and start appropriate chemotherapeutic treatment. PMID:26743307

    Background and Objectives: The mediastinum is a relatively uncommon site of distant metastases, which typically appear as peripheral lung nodules. We chose to assess the utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the diagnosis of distant metastases to the mediastinum. Materials and Methods: Over the period 2008–2013, a total of 446 patients with concurrent or previously diagnosed and treated extrathoracic malignancies were evaluated. Results: Surgical treatment was carried out in 414 patients (156 women and 237 men aged 26–68 years, mean age of 56.5 years) presenting with distant metastases to the lungs: Thoracoscopic wedge resection was completed in 393 patients and lobectomy and segmentectomy were performed in 7 and 14 patients, respectively. The median time from primary tumor resection was 6.5 years (range: 4.5 months to 17 years). Thirty-two of these patients underwent EBUS-TBNA for mediastinal manifestation of the underlying disease. EBUS-TBNA specimens were aspirated from the subcarinal or right paratracheal lymph node stations in 26 (81%) patients and from the hilar lymph nodes in 6 (18.8%) patients only. Metastases to lymph nodes were confirmed in 14 of these patients (43.8%). Primary lung cancer was diagnosed in seven patients. Mediastinoscopy was performed in two patients to reveal either lymph node metastasis or sarcoidosis. Thoracotomy for pulmonary metastases resection and mediastinal lymph node biopsy was performed in nine patients. Lymph node metastasis was confirmed in five patients (15.6%). The diagnostic efficacy, sensitivity, specificity, and negative predictive value (NPV) of EBUS-TBNA were 78.8%, 93.3%, 100%, and 87.5%, respectively. Conclusion: EBUS-TBNA is a valuable diagnostic tool in a selected group of patients with secondary tumors in the mediastinum and lungs. PMID:27386474

    Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive technique that allows lung cancer nodal staging and biopsy of parabronchial and paratracheal tissue. Its simplicity, high diagnostic yield, ability to diagnose both benign and malignant conditions, and exceedingly low complication rate has resulted in rapid widespread adoption by surgeons and physicians. EBUS-TBNA-related complications, however, do occur and need to be considered when assessing the risk-benefit profile of performing the procedure, and if the patient represents with unexpected symptoms after the procedure. We describe a 64-year-old woman who presented with a mediastinal abscess 5 days after EBUS-TBNA. This case demonstrates the importance of considering EBUS-TBNA-related complications to guide relevant imaging decisions and antibiotic choices. We review the published literature regarding infective complications of EBUS-TBNA and propose possible pathophysiologies. These complications are likely to increase in frequency as the technique is more widely adopted. PMID:24162119

    We report a case of acute neck cellulitis and mediastinitis complicating a continuous interscalene brachial plexus block. A 61-yr-old man was scheduled for an elective arthroscopic right shoulder rotator cuff repair. A continuous interscalene block was done preoperatively and 20 mL of 0.5% bupivacaine and 20 mL of 2% mepivacaine were injected through the catheter. Postoperative analgesia was provided by a continuous infusion of bupivacaine, 0.25% at 5 mL/h for 39 h using a 240-mL elastomeric disposable pump. The day after surgery, the patient complained of neck pain. The analgesic block was not fully effective. He was discharged home. Three days later, the patient was readmitted with neck edema and erythema, fever and fatigue. Neck ultrasonography and computed tomographic scan revealed an abscess of the interscalene and sternocleidomastiod muscles and cellulitis, as well as acute mediastinitis. Two blood cultures and surgical samples were positive for Staphylococcus aureus. The infection was treated with surgery, the site was surgically debrided, and a 2-mo course of vancomycin, imipenem, and oxacilline. The technique of drawing local anesthetic from the bottle and filling the elastomeric pump was the most likely cause of infection. This case emphasizes the importance of strict aseptic conditions during puncture, catheter insertion, and management of the local anesthetic infusate. PMID:18806062

    Background: In transplantation immunosuppression enhances the appearance of opportunist infections. An ideal balance between the prevention of rejection, the lowest risk of infections and the highest rates of graft survival is a continuous challenge. Lower doses of immunosuppression may diminish the risk of infections, metabolic and hemodynamic complications or even of malignancy, but may expose patients to episodes of acute rejection. New drugs are being developed to improve graft survival at the lowest risk of side effects. Belatacept has recently been introduced in kidney transplantation to inhibit the co-ligand signal of T cell stimulation. It is a drug with a safe profile, is well-tolerated and appears to improve long-term survival of kidney grafts. However, there may be an increase in opportunistic infections which may be facilitated by T cell depression, as Aspergillus sp., Cryptococcus neoformans or tuberculosis. Case Presentation: We describe a 59-year-old female who developed fever, clinical wasting and a mediastinal mass 31 months after receiving a living non-related kidney transplant while on belatacept therapy. A mediastinal node biopsy disclosed the presence of Histoplasma capsulatum. Infection successfully resolved after appropriate antifungal treatment. Conclusions: To our knowledge, this is the first reported case of Histoplasma capsulatum in a kidney transplanted patient on belatacept therapy PMID:27152295

    A woman in her 60s was evaluated for anterior chest pain. Computed tomography (CT) revealed a 50 mm mass with irregular contrast enhancement in the anterior mediastinum. α-fetoprotein (AFP) level was elevated to 1188 ng/mL. A germ cell tumor was diagnosed, mostly comprising of a yolk sac tumor (YST). Two courses of chemotherapy with cisplatin (CDDP) and etoposide (VP16) were administered and surgical tumor resection was then performed. The final diagnosis was YST. CDDP and VP16 were continued postoperatively; however, because the AFP level increased about six months after surgery, the chemotherapy regimen was altered to bleomycin and CPT-11. As the AFP again increased and a CT scan revealed tumor re-enlargement, recurrent YST was diagnosed and radiotherapy was administered. The patient received a total of 60 Gy (2 Gy per fraction). The tumor started to shrink during radiotherapy and AFP levels decreased. By one month post-radiotherapy, AFP levels had normalized and the tumor had disappeared. As of six years after radiotherapy, the patient remains alive without recurrence. Mediastinal YSTs are rare, and treatment usually includes surgery and preoperative and postoperative chemotherapy with cisplatin-based regimens. Successful treatment with radiotherapy has occasionally been reported. Our patient showed recurrence of a YST after surgery and chemotherapy, but achieved long-term survival after radiotherapy. Few patients with YST have undergone radiotherapy, but this approach was successful in our patient. In cases of postoperative recurrent YST resistant to chemotherapy, radiotherapy, together with salvage surgery, may offer a valuable option. PMID:27148423

    Patient: Female, 30 Final Diagnosis: Nocardiosis Symptoms: Cardiac tamponade • cough • dyspnea • hoarseness • mediastinal mass • pericardial effusion • short of breath Medication: — Clinical Procedure: — Specialty: Transplantology Objective: Rare disease Background: Nocardia infections can complicate solid organ transplantation. The usual clinical presentations include pulmonary infiltrates with or without cavitation and subcutaneous and brain abscesses. We report an unusual case of nocardia infection in a kidney transplant recipient that presented as mediastinal mass and was associated with pericardial tamponade. Case Report: A 30 year old African American renal transplant recipient presented with cough, hoarseness and shortness of breath nine months after kidney transplantation. She received basiliximab perioperatively and her maintenance immunosuppression included tacrolimus, mycophenolate mofetil and prednisone. Computed tomography (CT) showed a large mediastinal mass with a large pericardial effusion. An echocardiogram revealed collapse of the right ventricle consistent with tamponade. We performed emergent pericardiocentesis to treat the tamponade. A mediastinoscopic biopsy of the mediastinal mass was done to establish a diagnosis. The mediastinal biopsy confirmed the growth of Nocardia. After 2 weeks of imipenem and 6 weeks of linezolid, there was marked radiographic improvement in the size of the mediastinal mass. Conclusions: We report a rare case of a large mediastinal mass associated with pericardial tamponade from nocardia infection in a renal transplant recipient. An invasive approach may be necessary to obtain tissue diagnosis to direct treatment in these cases. Prompt and appropriate medical therapy leads to marked radiographic improvement. PMID:23940824

    One hundred and five primary mediastinal masses were seen between 1975 and 1998, at the Cardiothoracic surgical Unit of the University College Hospital Ibadan. These were studied to establish the importance of clinical features and plain chest radiography in preoperative evaluation of these masses. The sources of information were unit's record, cancer registry and the patients case note. The age range of the 75 male patients was 3 to 80 years (mean 35.2 +/- 22.1 year) and for the 30 female patients was 2.5 to 70 years (mean 30.9 +/- 18.6 years). Anterosuperior mediastinal masses were the most common (63.8%) followed by posterior mediastinal masses (22.9%). Middle mediastinal masses made up the remaining (13.3%). The most common primary mediastinal tumour was lymphoma (21.9%) next to which were thymus gland neoplasia and thymus cysts/hyperplasia (18.1%). Endocrine tumours (mainly goiters) constituted 17.1% of the masses. On the whole, 45 (42.9%) of the mediastinal tumours were malignant and 60 (57.1%) were benign. Eighty one patients (77.1%) were symptomatic at presentation, 24 patients (22.9%) were asymptomatic. Malignancy was more associated with symptoms in this series (82.2%) and benign lesion were more frequently (70.8%) asymptomatic. Cervical lymphadenopathy (78.6%), was more frequent in patients with malignant lesion. Tracheal deviation (60.3%) and neurological signs (78.9%) were more frequent in benign disease. Superior vena cava syndrome was more frequently associated with primary malignant mediastinal tumours. All masses (100%) were visualized on plain chest x-ray. On the basis of clinical features and chest x-ray, majority of patients (76.2%) with primary mediastinal masses had exploratory thoracotomy, sternotomy or biopsy of their mediastinal mass.

    Purpose: To report the clinical findings and long-term results of front-line, third-generation MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin) chemotherapy and mediastinal involved-field radiotherapy (IFRT) in 85 consecutive, previously untreated patients with primary mediastinal large B cell lymphoma (PMLBCL) diagnosed and managed at a single institution. Methods and Materials: Between 1991 and April 2004, 92 consecutive, untreated patients with PMLBCL were treated at our institution. The median age was 33 years (range, 15-61 years), 46 patients (50%) showed a mediastinal syndrome at onset; 52 patients (57%) showed a low/low-intermediate (0 to 1) and 40 patients (43%) an intermediate-high/high (2 to 3) International Prognostic Index (IPI) score. Eighty-five patients were treated with standard chemotherapy (MACOP-B), and 80 underwent mediastinal IFRT at a dose of 30-36 Gy. Results: After a MACOP-B regimen, the overall response rate was 87% and the partial response rate 9%. After chemotherapy, {sup 67}Ga scintigraphy/positron emission tomography results were positive in 43 of 52 patients (83%), whereas after IFRT 11 of 52 patients (21%) remained positive (p < 0.0001). After a median follow-up of 81 months (range, 2-196 months), progression or relapse was observed in 15 of 84 patients (18%). The projected 5-year overall survival and progression-free survival rates were 87% and 81%, respectively. The 5-year overall survival and progression-free survival rates were better for patients with an IPI of 0 to 1 than for those with an IPI of 2 to 3 (96% vs. 73% [p = 0.002] and 90% vs. 67% [p = 0.007], respectively). Conclusions: Combined-modality treatment with intensive chemotherapy plus mediastinal IFRT induces high response and lymphoma-free survival rates. Involved-field RT plays an important role in inducing negative results on {sup 67}Ga scintigraphy/positron emission tomography in patients responsive to chemotherapy.

    Patients with mediastinal masses present unique challenge to anesthesiologists. Patients with anterior mediastinal masses have well documented cases of respiratory or cardiovascular collapse during anesthesia and in postoperative period. Masses in the posterior mediastinum have been traditionally regarded to carry a significantly lower risk of anesthesia related complications but cases of near fatal cardiorespiratory complications have been reported. We describe anesthetic management of a patient with posterior mediastinal mass compressing the trachea and the left main bronchus presented for left thoracotomy and tumor excision. The patient experienced pain and cough, and exhibited positional dyspnea. Airway was successfully secured with awake nasotracheal intubation and placement of single lumen endobronchial tube.

    Four cases of anterior mediastinal tracheostomy with myocutaneous Pectoralis Major flap are described. Resection of the manubrium, clavicular heads and the cartilages of the first and second ribs is necessary. The use of myocutaneous Pectoralis Major flap give good functional results. No infection or hemorrhage of mediastinal great vessels occurred. The indications of Anterior mediastinal tracheostomy are discussed. Stomal and peristomal recurrences following laryngectomy for carcinoma represents the indication of choice. Stomal recurrences are difficult to treat and the prognostic is poor.

    Mediastinal germ cell tumors are extragonadal germ cell tumors (EGGCTs) commonly seen in children and young adults. They are more common in men. Clinically they are classified as teratomas, seminomas, and nonseminomatous germ cell tumors. Primary mediastinal yolk sac neoplasm is an extremely rare tumor. We present here a very rare case of primary yolk sac tumor of the anterior mediastinum in a 73-year-old male. Mediastinal germ cell tumors have a worse prognosis than gonadal germ cell tumors. Chemotherapy followed by adjuvant surgery improves overall response in EGGCTs. However, comorbidities can render treatment with chemotherapy and surgery challenging in elderly patients.

There were a large soft tissue density oval mass in the caudal mediastinum on thoracic radiographs, a fluid-filled oval mass in the caudal mediastinum on ultrasonography, and left-sided and ventrally displaced and compressed esophagus on esophagram. On esophageal endoscopy, there were no esophageal abnormalities. CT findings with a fluid filled mass with rim enhancement indicated a caudal mediastinal paraesophageal abscess. The patient was treated with oral antibiotics, because the owner declined percutaneous drainage and surgery. The patient was admitted on emergency with severe respiratory distress; and ruptured abscess and deteriorated pleuropneumonia were suspected. With intensive hospitalization care and additional antibiotic therapy, the patient had full recovery. PMID:25648207

    Invasive fungal infections are a considerable cause of morbidity, mortality, increased hospital stay durations, and high health care costs, during neonatal period. In this period, the premature infants are the most affected. Candida species are the leading cause of invasive fungal infections. The majority of neonatal Candida infections are caused by C. albicans, C. parapsilosis, C. glabrata and C. tropicalis, although other fungus species are being reported. One such emerging pathogen is K. ohmeri. This organism has been reported as a pathogen in the neonatal period, principally in premature infants. The risk factors associated with fungal infection are central line, immunosuppression, prolonged hospital stay, endotracheal intubation and exposure to antibiotics. We present a term baby with a mediastinal mass, who required several procedures, as pericardiocentesis, central catheters, mechanical ventilation, antibiotics. During his evolution, he presented infection by K. ohmeri. The baby was treated with amphotericin B, with satisfactory clinical course. PMID:27606654

    Teratomas are rare tumors in the mediastinum. Benign cystic teratomas of anterior mediastinum are rarely complicated by rupture into an adjacent body cavity. Such rupture, however, is usually associated with life-threatening complications. We present a case with spontaneous rupture of mediastinal cystic teratoma. The patient was evaluated with chest radiograph, computed tomography (CT) and magnetic resonance imaging (MRI). A complex mass including predominantly cystic components was detected in the left anterior mediastinum. After surgery, pathologic diagnosis was reported as mature cystic teratoma. High levels of amylase and lipase were detected in both the cystic fluid and serum. This finding supported the hypothesis of autolysis for the explanation of rupture. In addition, carbohydrate antigen (CA) 19-9, CA 125 and carcinoembryonic antigen (CEA) levels were high in the cystic fluid. PMID:15236127

    Gunshot wounds that traverse the mediastinum frequently cause serious injury to the cardiac, vascular, pulmonary, and digestive structures contained within. Most patients present with unstable vital signs signifying the need for emergency operation. An occasional patient will present with stable vital signs. Work-ups for such a patient may range from surgical exploration to radiographic and endoscopic testing to mere observation. We report our experience with diagnostic work-up of the stable patient with a transmediastinal gunshot wound. All stable patients who present to our urban level I trauma center following a transmediastinal gunshot wound undergo diagnostic work-up consisting of chest radiograph, cardiac ultrasound, angiography, esophagoscopy, barium swallow, and bronchoscopy. The work-up is dependent on the trajectory of the missile. Information on these patients is kept in a prospective database maintained by the trauma attending physicians. This database was analyzed and comparisons were made using Student's t-test and the Fisher exact c2 as appropriate. Over a 68-month period, 50 stable patients were admitted following a transmediastinal gunshot wound. All of these patients had a chest radiograph followed by one or more of the above tests. 8 patients (16%) were found to have a mediastinal injury (4 cardiac, 3 vascular, and 1 tracheo-esophageal) requiring urgent operation (group 1). The remaining 42 patients (84%) did not have a mediastinal injury (group 2). There was no difference between groups with respect to blood pressure, pulse, respiratory rate, pH, base deficit, or initial chest tube output. There was one death in each group, and three complications in group 2. Patients may appear stable following a transmediastinal gunshot wound, even when they have life-threatening injuries. There is no difference in vital signs, blood gas, or hemothorax to indicate which patients have serious injuries. We advocate continued aggressive work-up of these patients

    Background This study aimed to evaluate the therapeutic results and safety of pectoralis major muscle turnover flaps in the treatment of mediastinitis after coronary artery bypass grafting (CABG) procedures. Methods Data regarding 33 patients with post-CABG deep sternal wound infections (DSWIs) who underwent pectoralis major muscle turnover flap procedures in the Emam Reza and Ghaem Hospitals of Mashhad, Iran were reviewed in this study. For each patient, age, sex, hospital stay duration, remission, recurrence, and associated morbidity and mortality were evaluated. Results Of the 2,447 CABG procedures that were carried out during the time period encompassed by our study, DSWIs occurred in 61 patients (2.5%). Of these 61 patients, 33 patients (nine females [27.3%] and 24 males [72.7%]) with an average age of 63±4.54 years underwent pectoralis major muscle turnover flap placement. Symptoms of infection mainly occurred within the first 10 days after surgery (mean, 10.24±13.62 days). The most common risk factor for DSWIs was obesity (n=16, 48.4%) followed by diabetes mellitus (n=13, 39.4%). Bilateral and unilateral pectoralis major muscle turnover flaps were performed in 20 patients (60.6%) and 13 patients (39.4%), respectively. Complete remission was achieved in 25 patients (75.7%), with no recurrence in the follow-up period. Four patients (12.1%) needed reoperation. The mean hospitalization time was 11.69±6.516 days. Four patients (12.1%) died during the course of the study: three due to the postoperative complication of respiratory failure and one due to pulmonary thromboembolism. Conclusion Pectoralis major muscle turnover flaps are an optimal technique in the treatment of post-CABG mediastinitis. In addition to leading to favorable therapeutic results, this flap is associated with minimal morbidity and mortality, as well as a short hospitalization time. PMID:26290837

    Mediastinal emphysema is a status of gas retention in mediastinum, usually caused by airway system injury or esophagus rupture. Healthy people without trauma and basic disease emerging unexplained mediastinal emphysema are called idiopathic mediastinal emphysema. While tension pneumomediastinum is an exceptional and potentially lethal condition, the increased intramediastinal pressure with a severe oppression of heart, vena cava and pulmonary vein leads to impaired central venous return through the cavae system, restricted right heart diastolic filling, and collapse of the cardiac chambers, resulting in reduced stroke volume, cardiac output and dysaemia. This young people-prone disease was initially reported by Hamman in 1939 and usually has a good prognosis so that no special treatments were needed. In this study, however, we presented a young boy with idiopathic tension mediastinal emphysema combined with dysaemia and respiratory failure. Fortunately, he was finally successful treated by VATS after heteropathy and incision on suprasternal fossae. PMID:26770618

    The authors illustrate a case of right neonatal congenital diaphragmatic hernia (CDH) of Bochdalek with major pulmonary hypoplasia and postoperative massive mediastinal displacement to the right, leading to tracheal compression and recurrent respiratory distress at every attempt to wean the infant from the ventilator. Mediastinal stabilization was obtained by placing an expansion prosthesis (of the cutaneous type) in the right hemithorax, to prevent mediastinal obstruction of the main airways. This procedure may prove to be an original and efficient solution for the critical postoperative respiratory obstruction due to severe pulmonary hypoplasia and mediastinal mass effect in the newborn with CDH. However, this may not prevent progressive scoliosis, a serious problem frequently seen in the absence of one lung. PMID:8555135

    After cardiac transplantation, bacterial mediastinitis is a rare but dangerous early complication. Of the 113 patients who underwent heart or heart-lung transplantation at our hospital from August 1981 to April 1989, 8 developed purulent mediastinitis. Treatment involved surgical débridment, local irrigation, drainage, and high-dose systemic antibiotics. No patient died of an acute mediastinal infection. In 2 cases, however, chronic mediastinitis led to the formation of a huge mycotic aneurysm of the ascending aorta. Eleven days after surgical intervention for rupture, 1 patient died of aneurysmal rerupture; the 2nd patient remains well 16 months after prosthetic replacement of the ascending aorta and reconstruction of the necrotic proximal portion of the left coronary artery with a saphenous vein patch.

    Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) had an enormous impact on the current advancement in diagnostic bronchoscopy. The aims of the present study were: (1) to evaluate the added value of EBUS-TBNA to routine diagnostic bronchoscopy performed in patients with mediastinal lymph node enlargement and (2) to identify factors that affect the diagnostic yield of EBUS-TBNA. We retrospectively analyzed 712 EBUS-TBNA procedures out of the 4081 bronchoscopies performed in the years 2009-2014. The number of EBUS-TBNA procedures increased from 61 (8.8 % of all bronchoscopies) in 2009 to 160 (21.4 %) in 2014. In 625 (87.8 %) patients adequate cytological material was obtained. Based on cytological examination of EBUS-TBNA aspirates, specific diagnosis was made in 367 (51.5 %) patients. The forceps biopsy of endobronchial lesions provided specific diagnosis in only 204 (28.6 %) patients. The percentage of patients with EBUS-TBNA based diagnosis increased steadily from 34.4 % in 2009 to 65.0 % in 2014 (p < 0.0001). The median lymph node diameter in patients with positive EBUS-TBNA findings was 20 (IQR 15-30) mm and was significantly larger than that in patients with negative EBUS-TBNA results (15 (IQR 10-20) mm, p = 0.0001). The highest diagnostic yield (78.5 %) was found in patients with lymph node dimension between 31 mm and 40 mm. We conclude that EBUS-TBNA is a valuable diagnostic method in an unselected group of patients with mediastinal lymph node enlargement. The percentage of positive EBUS-TBNA diagnoses is related to lymph node dimensions. The overall efficacy of EBUS-TBNA improves with increasing years of experience. PMID:26987324

    An ultrasound examination of the thorax of three horses which were performing poorly or had mild signs of colic showed that they had a cranial mediastinal mass and a pleural effusion. A cytological examination of the pleural fluid showed that it did not contain neoplastic cells. A histological examination of an ultrasound-guided core biopsy of the cranial mediastinal mass showed that in each of the three horses it was a lymphosarcoma. PMID:15214516

    Tracheomalacia is a disorder of the large airways that is often caused by a large anterior mediastinal mass. This study describes 7 patients who underwent controlled trachea suspension as a surgical intervention to prevent severe tracheomalacia and provide potent relief of airway symptoms. All patients recovered well. The results demonstrate this procedure may be safe and effective for resection of a large mediastinal mass compressing the trachea with collapsed segments. PMID:26046890

    The mortality rates from descending necrotizing mediastinitis (DNM) are between 25 and 40 % mainly because of delayed diagnosis and inappropriate surgical treatment. This study was undertaken to examine two surgical options for DNM and determine the optimal surgical option for DNM of the anterior mediastinum. Fifteen cases of DNM of the anterior mediastinum, January 2001 and October 2010, were retrospectively reviewed. Eleven were anterosuperior mediastinitis, with infection located above the tracheal bifurcation and four had infections involving the entire anterior mediastinum. Depending on the location of mediastinitis, open drainage of the submandibular and neck abscesses, in addition to other surgical treatments, was performed. If the infection was anterosuperior, transcervical mediastinal drainage or thoracotomy was performed. If the entire anterior mediastinum was involved, necrotic tissue was removed with thoracoscopic via subxiphoid incision, the bilateral pleurae were opened for drainage, and a tunnel connecting the neck incision and the subxiphoid incision through the whole anterior mediastinum was made for drainage. The anterosuperior mediastinitis cases were treated with either transcervical mediastinal drainage (n = 8) or thoracotomy (n = 3). Patients healed after an average of 24.5 and 20.0 days in the hospital, respectively. For the four other cases, one patient died of septic shock, while the other three patients were healed after and an average of 43.3 days in the hospital. Mortality rate was 6.7 %. The surgical procedure used to treat DNM should be selected according to the location of the infection. DNM involving the anterosuperior mediastinum can be treated by transcervical mediastinal drainage. If anterosuperior mediastinitis spreads to the side of the trachea, open thoracotomy is a suitable therapy. If the entire anterior mediastinum is involved, debridement and drainage of the anterior mediastinum should be performed with a thoracoscope via

    As the number of Hodgkin's lymphoma (HL) survivors grows, understanding long-term complications becomes more important. Mediastinal radiotherapy (MRT) seems to cause valvular disease, and the prevalence might increase during follow-up. In this cross-sectional study 82 HL survivors participated (52% men, mean age 47.8 years, 50 treated with MRT). Valvular disease was diagnosed by transthoracic echocardiography and compared between HL survivors treated with and without MRT. Univariate and multivariate logistic regression analysis was used to identify predictors for valvular disease. During a median follow-up of 13.4 years (range 2 to 39 years), ≥ mild valvular disease was present in 61.2% of HL survivors with MRT (n = 30), compared with 31.0% of HL survivors without MRT (n = 9; odds ratio [OR] 3.51, 95% CI 1.32 to 9.30, p = 0.01). In multivariate analysis, only current age remained predictive for ≥ mild valvular disease (OR 1.08 per year, 95% CI 1.01 to 1.14, p = 0.023). Aortic regurgitation (AR) was most prevalent and irradiated patients had significantly more ≥ mild AR (38.2% vs 6.8%, p = 0.007). Within the MRT subgroup, time after radiation of >15 years was associated with AR (OR 4.70, 95% CI 1.05 to 21.03, p = 0.043), after adjusting for current age and hypertension. Severe valvular disease was present in 24.5% of HL survivors with MRT compared with 3.4% without MRT (p = 0.016). Valvular surgery was performed in 9 HL survivors (18.0%) with MRT and in none without MRT. In conclusion, the prevalence of valvular disease in HL survivors treated with MRT is high and increases with time after irradiation. Long-time screening for valvular disease by transthoracic echocardiography might be worthwhile. PMID:26772441

    The prognosis of patients with primary mediastinal large B-cell lymphoma has improved over recent years. However, the optimal treatment strategy including the role of radiotherapy remains unknown. We retrospectively analyzed the clinical outcomes of 345 patients with newly diagnosed primary mediastinal large B-cell lymphoma in Japan. With a median follow up of 48 months, the overall survival at four years for patients treated with R-CHOP (n=187), CHOP (n=44), DA-EPOCH-R (n=9), 2nd- or 3rd-generation regimens, and chemotherapy followed by autologous stem cell transplantation were 90%, 67%, 100%, 91% and 92%, respectively. Focusing on patients treated with R-CHOP, a higher International Prognostic Index score and the presence of pleural or pericardial effusion were identified as adverse prognostic factors for overall survival in patients treated with R-CHOP without consolidative radiotherapy (IPI: hazard ratio 4.23, 95% confidence interval 1.48–12.13, P=0.007; effusion: hazard ratio 4.93, 95% confidence interval 1.37–17.69, P=0.015). Combined with the International Prognostic Index score and the presence of pleural or pericardial effusion for the stratification of patients treated with R-CHOP without radiotherapy, patients with lower International Prognostic Index score and the absence of effusion comprised approximately one-half of these patients and could be identified as curable patients (95% overall survival at 4 years). The DA-EPOCH-R regimen might overcome the effect of these adverse prognostic factors. Our simple indicators of International Prognostic Index score and the presence of pleural or pericardial effusion could stratify patients with primary mediastinal large B-cell lymphoma and help guide selection of treatment.

    165 percutaneous biopsies of anterior, middle and posterior mediastinum lesions were performed to 156 patients. Procedure was guided by US in 40 cases, by CT - in 125 cases. Hydrodissection was used in 5 cases, artificial pneumothorax - in 3 cases in order to avoid transpulmonary needle pass. Post-biopsy CT scan was performed and patients observed for any complications. Adequate tissue for histological diagnosis was obtained in 156 (94.5%) cases at the first attempt; in 9 (5.5%) cases the repeated procedure was needed. No major complications were detected after biopsy procedures; minor complications (pneumothorax, hemothorax and hemophtysis) were detected in 23 (13.9%) cases. No complications were detected after US guided procedures; In 17 (10.3% of all complications) cases pneumothorax, in 4 (2.4%) cases - hemothorax and in 2 (1.2%) cases hemophtisis was detected on CT guided procedures. All hemothorax and hemophtisis and 10 pneumothorax cases happened to be self-limited; in 3 pneumothorax cases aspiration and in 4 cases - pleural drainage was needed. Percutaneous image-guided core biopsy of mediastinal lesions is an accurate and safe procedure, which enables to get the tissue material from all mediastinum compartments. Ultrasound is the most efficient for biopsy guidance, if the target is adequately imaged by it; the advantages of US guidance are: a) possibility of real-time needle movement control b) possibility of real-time blood flow imaging b) noninvasiveness c) cost-effectiveness d) possibility to perform the biopsy at the bedside, in a semiupright position; so, ultrasound is a "Gold Standard" for procedure guidance if the 'target" can be adequately imaged by this technique. If US guidance is impossible biopsy should be performed under CT guidance. Hydrodissection and artificial pneumothorax enables to avoid the lung tissue penetration related complications. Pneumothorax was associated with multiple Needle passes and larger diameter needle use. The safety

    Background Mediastinitis is a rare, but serious complication of cardiac surgery. It has a significant socioeconomic impact and high morbidity. The purpose of this study was to determine pre-, intra-, and postoperative predictors of mediastinitis. Methods and results In 1700 consecutive patients, who underwent cardiac surgery in 2001, 49 variables were retrospectively assessed. Forty-five patients (2.65%, 95% CI [1.88; 3.41]) developed postoperative mediastinitis. None of these patients died during their hospitalization. Multivariate analysis identified three of the 49 variables as highly significant independent predictors for the development of mediastinitis: obesity (OR 1.03, 95% CI [1.01; 1.04] p = 0.001), chronic obstructive pulmonary disease (OR 3.30, 95% CI [1.58; 6.88], p = 0.001), and bilateral grafting of the internal mammary artery (OR 3.18, 95% CI [1.20; 8.43] p = 0.02). The model is reliable in terms of its goodness of fit, it also discriminates well. Additionally, univariate analysis identified diabetes mellitus, CCS class and the number of intraoperatively transfused units of fresh frozen plasma as variables with a significant impact. Conclusion The present study suggests that bilateral IMA grafting, chronic obstructive pulmonary disease and obesity are important predictors of mediastinitis. PMID:17511885

  1. Diagnosing gestational diabetes.

    Ryan, E A

    2011-03-01

    The newly proposed criteria for diagnosing gestational diabetes will result in a gestational diabetes prevalence of 17.8%, doubling the numbers of pregnant women currently diagnosed. These new diagnostic criteria are based primarily on the levels of glucose associated with a 1.75-fold increased risk of giving birth to large-for-gestational age infants (LGA) in the Hyperglycemia Adverse Pregnancy Outcome (HAPO) study; they use a single OGTT. Thus, of 23,316 pregnancies, gestational diabetes would be diagnosed in 4,150 women rather than in 2,448 women if a twofold increased risk of LGA were used. It should be recognised that the majority of women with LGA have normal glucose levels during pregnancy by these proposed criteria and that maternal obesity is a stronger predictor of LGA. The expected benefit of a diagnosis of gestational diabetes in these 1,702 additional women would be the prevention of 140 cases of LGA, 21 cases of shoulder dystocia and 16 cases of birth injury. The reproducibility of an OGTT for diagnosing mild hyperglycaemia is poor. Given that (1) glucose is a weak predictor of LGA, (2) treating these extra numbers has a modest outcome benefit and (3) the diagnosis may be based on a single raised OGTT value, further debate should occur before resources are allocated to implementing this change.

In our case, a 30-year-old patient was admitted due to thoracic pain, dyspnea, orthopnea, cough, hoarseness and weight loss over a 3-month period as well as a dramatic worsening a week before the admission. A chest radiography showed a completely white left hemithorax and contralateral mediastinal shift; in addition, a chest tomography revealed a giant heterogeneous mediastinal mass, lung atelectasia and a small pleural effusion. The patient was submitted to Chamberlain procedure (biopsy) under local anesthesia and the diagnosis of a synovial sarcoma was obtained after immunohistochemical analysis. Due to his poor general condition, he received chemotherapy first, with a dramatic response, after what, the mass that had been reduced was removed surgically. After a 5-year- follow-up period there are no signs of disease recurrence. PMID:23372956

    Sonographic findings correlated with necropsy findings in 8 of 9 horses in which the cranial portion of the mediastinum was evaluated by use of both methods. Cranial mediastinal masses were imaged as multilobular and homogeneously hypoechoic; a complex echogenic pattern was observed with necrosis within the mass. Pleural effusion was a common finding in horses with mediastinal lymphosarcoma. Cytologic evaluation of pleural fluid samples was useful in diagnosis of lymphosarcoma in 10 of 12 horses that had thoracentesis. Sonographic examination of the thorax and cranial portion of the mediastinum can aid in the diagnosis of mediastinal lymphosarcoma in horses. Such examination should be performed in horses with clinical signs of cranial vena cava obstruction in which pleural effusion is detected, or when thoracic lymphosarcoma is suspected. PMID:7698925

    Renal cell carcinoma (RCC) may metastasize to mediastinal lymph nodes without any abdominal lymph node involvement. The present study describes an autopsy-proven case of RCC presenting with a large mediastinal mass; the case had been previously misdiagnosed as small cell lung carcinoma due to imaging analysis results, an elevated serum level of neuron-specific enolase and the presence of small atypical cells with a high nuclear/cytoplasmic ratio. Despite RCC occurrence being rare, it should be considered in the differential diagnosis, particularly when a mass located in the kidneys presents with metastases to the mediastinal lymph nodes, even if there is no involvement of the abdominal lymph nodes and the primary lesion is of a small size.

    Precursor T lymphoblastic lymphoma (T-LBL) often manifests as a mediastinal mass sometimes compressing vital structures like vessels or large airways. This case was a 40-year-old male who developed T-LBL presenting as respiratory failure caused by mediastinal T-LBL. He presented with persistent life threatening hypoxia despite tracheal intubation. We successfully managed this respiratory failure using venovenous (VV) ECMO. Induction chemotherapy was started after stabilizing oxygenation and the mediastinal lesion shrank rapidly. Respiratory failure caused by compression of the central airway by tumor is an oncologic emergency. VV ECMO may be an effective way to manage this type of respiratory failure as a bridge to chemotherapy. PMID:25580133

    Historically, feline mediastinal lymphoma has been associated with young age, positive feline leukaemia virus (FeLV) status, Siamese breed and short survival times. Recent studies following widespread FeLV vaccination in the UK are lacking. The aim of this retrospective multi-institutional study was to re-evaluate the signalment, retroviral status, response to chemotherapy, survival and prognostic indicators in feline mediastinal lymphoma cases in the post-vaccination era. Records of cats with clinical signs associated with a mediastinal mass and cytologically/histologically confirmed lymphoma were reviewed from five UK referral centres (1998-2010). Treatment response, survival and prognostic indicators were assessed in treated cats with follow-up data. Fifty-five cases were reviewed. The median age was 3 years (range, 0.5-12 years); 12 cats (21.8%) were Siamese; and the male to female ratio was 3.2:1.0. Five cats were FeLV-positive and two were feline immunodeficiency-positive. Chemotherapy response and survival was evaluated in 38 cats. Overall response was 94.7%; complete (CR) and partial response (PR) rates did not differ significantly between protocols: COP (cyclophosphamide, vincristine, prednisone) (n = 26, CR 61.5%, PR 34.0%); Madison-Wisconsin (MW) (n = 12, CR 66.7%, PR 25.0%). Overall median survival was 373 days (range, 20-2015 days) (COP 484 days [range, 20-980 days]; MW 211 days [range, 24-2015 days] [P = 0.892]). Cats achieving CR survived longer (980 days vs 42 days for PR; P = 0.032). Age, breed, sex, location (mediastinal vs mediastinal plus other sites), retroviral status and glucocorticoid pretreatment did not affect response or survival. Feline mediastinal lymphoma cases frequently responded to chemotherapy with durable survival times, particularly in cats achieving CR. The prevalence of FeLV-antigenaemic cats was low; males and young Siamese cats appeared to be over-represented. PMID:24366846

    Invasive infections due to carbapenem-resistant Enterobacteriaceae (CRE), including polymyxin-resistant (PR-CRE) strains, are being increasingly reported. However, there is a lack of clinical data for several life-threatening infections. Here we describe a cohort of patients with post-surgical mediastinitis due to CRE, including PR-CRE. This study was a retrospective cohort design at a single cardiology centre. Patients with mediastinitis due to CRE were identified and were investigated for clinically relevant variables. Infecting isolates were studied using molecular techniques. Patients infected with polymyxin-susceptible CRE (PS-CRE) strains were compared with those infected with PR-CRE strains. In total, 33 patients with CRE mediastinitis were studied, including 15 patients (45%) with PR-CRE. The majority (61%) were previously colonised. All infecting isolates carried blaKPC genes. Baseline characteristics of patients with PR-CRE mediastinitis were comparable with those with PS-CRE mediastinitis. Of the patients studied, 70% received at least one agent considered active in vitro and most patients received at least three concomitant antibiotics. Carbapenem plus polymyxin B was the most common antibiotic combination (73%). Over 90% of patients underwent surgical debridement. Overall, in-hospital mortality was 33% and tended to be higher in patients infected with PR-CRE (17% vs. 53%; P=0.06). In conclusion, mediastinitis due to CRE, including PR-CRE, can become a significant challenge in centres with CRE and a high cardiac surgery volume. Despite complex antibiotic treatments and aggressive surgical procedures, these patients have a high mortality, particularly those infected with PR-CRE. PMID:27155944

    Patients in traffic accidents are usually presented with pain and bleeding due to fractures or soft tissue injury. On some occasions, more severe complications may be triggered by the trauma. A review of the published English language literature reveals no survival case once the traumatic mediastinal hematoma is ruptured. In our case, a 54-year-old man suffering motorcycle accident was admitted to emergency department. Computed tomography scan revealed subdural hematoma combined with posterior mediastinal hematoma. The patient was saved and discharged with a satisfactory outcome. Here we hope to share our treatment experience in dealing with the patient with severe multiple trauma. PMID:27033275

    Anesthetic management of superior vena cava syndrome carries a possible risk of life-threatening complications such as cardiovascular collapse and complete airway obstruction during anesthesia. Superior vena cava syndrome results from the enlargement of a mediastinal mass and consequent compression of mediastinal structures resulting in impaired blood flow from superior vena cava to the right atrium and venous congestion of face and upper extremity. We report the successful anesthetic management of a 42-year-old man with superior vena cava syndrome posted for cervical lymph node biopsy. PMID:22557753

    Abnormal mediastinal air may be caused by inhalational illicit drug use subsequent to barotrauma resulting from coughing after deep inhalation and breath holding. It may also arise from oesophageal rupture due to retching after ingestion of the illicit drug. The history can alert the practitioner to this cause of chest pain. As chest radiographs are widely accessible and mediastinal air is easily recognisable, the chest radiograph should be included and carefully scrutinised in the diagnostic workup of chest pain in the recreational drug abuser. It is prudent to exclude oesophageal rupture, particularly in the setting of retching, before deciding on conservative and expectant management. PMID:27138662

    Candida mediastinitis is a rare complication of open heart surgery with high mortality and morbidity usually associated with C. albicans. We are reporting the case of a 57 year old male who after having a triple coronary artery bypass graft procedure, had mediastinitis caused by Candida famata, a yeast, that had only been reported once before as the causal agent of this condition. It is of vital importance, that future cases be reported, due to the fact that both reported cases have led to patient demise. PMID:27419075

    This audit examined key performance indices related to endobronchial ultrasound (EBUS)-guided mediastinal lung cancer staging before and after the introduction of defined quality standards, at four independent EBUS centres in one cancer network. Data from 642 procedures were prospectively collected and analysed. The introduction of standards was associated with a significant increase (p<0.001) in sampling of key mediastinal lymph node stations (4R, 4L and 7) and a reduction in the variability of staging sensitivity between centres.

    By cannulating the efferent duct of the caudal mediastinal lymph node in sheep, lymph from the lower respiratory tract was collected under physiological conditions for several days. In 18 such preparations the flow rate varied from 4 to 12 ml/hr between individuals and the lymphocyte count between 4000 and 117,000/mm3. The protein content of the lymph plasma averaged nearly 60% of that of the blood, and this indication of the high permeability of the capillary bed of the lungs was confirmed by measuring the time taken for intravenous doses of 125I-albumin to equilibrate between the blood and mediastinal lymph plasma. The concentration of immunoglobulin A was higher in the mediastinal lymph than in blood serum, while the reverse was true of the concentrations of IgG1, IgG2, and IgM. This evidence for the local production of IgA by the intra thoracic lymphoid tissue was supported by the demonstration by immunoperoxidase techniques of IgA-containing plasma cells in sections cut from the caudal mediastinal nodes, and of IgA-containing immunoblasts in the lymph.

    The purpose of this study was to determine the intra and interfraction motion of mediastinal lymph node regions. Ten patients with nonsmall-cell lung cancer underwent controlled inhale and exhale computed tomography (CT) scans during two sessions (40 total datasets) and mediastinal nodal stations 1-8 were outlined. Corresponding CT scans from different sessions were registered to remove setup error and, in this reference frame, the centroid of each nodal station was compared for right-left (RL), anterior-posterior (AP), and superior-inferior (SI) displacement. In addition, an anisotropic volume expansion encompassing the change of the nodal region margins in all directions was used. Intrafraction displacement was determined by comparing same session inhale-exhale scans. Interfraction reproducibility of nodal regions was determined by comparing the same respiratory phase scans between two sessions. Intrafraction displacement of centroid varied between nodal stations. All nodal regions moved posteriorly and superiorly with exhalation, and inferior nodal stations showed the most motion. Based on anisotropic expansion, nodal regions expanded mostly in the RL direction from inhale to exhale. The interpatient variations in intrafraction displacement were large compared with the displacements themselves. Moreover, there was substantial interfractional displacement ({approx}5 mm). Mediastinal lymph node regions clearly move during breathing. In addition, deformation of nodal regions between inhale and exhale occurs. The degree of motion and deformation varies by station and by individual. This study indicates the potential advantage of characterizing individualized nodal region motion to safely maximize conformality of mediastinal nodal targets.

    Primary mediastinal seminomas are unusual tumors that can present in a pure form or as part of a mixed germ cell tumor. Contrary to testicular seminomas, little is known about the expression of novel immunohistochemical markers in mediastinal seminomas. This study investigates the immunohistochemical features of these tumors with a focus on novel markers. Thirty-two cases of primary mediastinal seminomas were reviewed; and representative whole-tissue sections were selected for immunohistochemical studies using antibodies directed against high molecular weight cytokeratin 5/6 (CK5/6), low molecular weight cytokeratin (CAM5.2), octamer-binding transcription factor 3/4 (OCT3/4), spalt-like transcription factor 4 (SALL4), GATA binding protein 3 (GATA-3), sry-related HMG box 2 (SOX2), SOX17, human T cell leukemia/lymphoma 1 (TCL1), glypican 3, melanoma associated antigen C2 (MAGEC2), and paired box gene 8 (Pax8). The percentage of positive tumor cells as well as the intensity of staining was evaluated and scored. Thirty-one cases (97%) expressed SOX17, whereas 29 cases (91%) were positive for OCT3/4 and SALL4, respectively. Twenty-eight cases (88%) expressed MAGEC2 and CAM5.2, respectively. Two cases (6%) were positive for Pax8, and a single case (3%) was positive for TCL1. None of the cases stained with CK5/6, GATA-3, SOX2, or glypican 3. Similar to testicular seminomas, mediastinal seminomas show consistent expression of OCT3/4, SALL4, SOX17, and MAGEC2 and are negative for SOX2, glypican 3, GATA-3, and CK5/6. Pax8 positivity is only inconsistently identified in mediastinal seminomas. Contrary to their testicular counterparts, mediastinal tumors show diffuse expression of low-molecular-weight cytokeratin in up to 90% of cases and are commonly negative for TCL1. Although there is some immunohistochemical overlap between testicular and mediastinal seminomas, considerable differences also exist and should be acknowledged when dealing with these tumors.

    Background The greater omentum has been found to be immunologically competent in protecting abdominal organs from inflammation. Anastomotic omentoplasty has been used and proven effective in preventing anastomotic leaks after an esophagectomy. However, pulmonary complications are still a substantial problem after an esophagectomy. This study investigated the benefits of mediastinal transposition of the omentum, a modification of the conventional omental wrapping technique, in controlling overall postoperative intrathoracic complications. Methods From January 2010 to March 2015, 208 consecutive patients receiving an open Ivor-Lewis esophagectomy at our institution were retrospectively reviewed. One hundred twenty-one patients with omentum mediastinal transposition were assigned to the transposition group and 87 patients without omental transposition were placed in the non-transposition group. The patients’ demographics, postoperative short-term outcomes, and in-hospital cost were documented and analyzed. Results Mediastinal transposition of the omentum led to a shorter postoperative hospital stay (14 vs. 16 d, P=0.038) and a lower intrathoracic infection rate (30.6% vs. 48.3%, P=0.009). Intrathoracic infection was milder in the transposition group (P=0.005), though a non-significant was found in overall complications (P=0.071). The multivariate logistic regression analyses identified omentum mediastinal transposition (P=0.007, OR=0.415) as an independent protective factor for postoperative intrathoracic infection. The total in-hospital cost was comparable in both groups (P>0.05), whereas the pharmacy cost was lower in the transposition group than in the non-transposition group (¥21,668 vs. ¥27,012, P=0.010). Conclusions Mediastinal transposition of the omentum decreases the rate and severity of postoperative intrathoracic infection following an open Ivor-Lewis esophagectomy. This result in decreased pharmacy costs, rather than resulting in an increased economic

    INTRODUCTION: Posterior mediastinal goitres constitute of a unique surgical thyroid disorder that requires expert management. Occasionally, they require thoracic approach for the completion of thyroidectomy. In this paper, we describe the feasibility and utility of a novel thoracoscopic approach for such goitres. MATERIALS AND METHODS: This is a retrospective study conducted at a tertiary care endocrine surgery department in South India over a period of 5 years from January 2010 to December 2014. We developed a novel thoracoscopic technique for posterior mediastinal goitres instead of a more morbid thoracotomy or sternotomy. All the clinical, investigative, operative, pathological and follow-up data were collected from our prospectively filled database. Statistical analysis was done with SPSS 15.0 version. Descriptive analysis was done. OPERATIVE TECHNIQUE OF THORACOSCOPIC THYROIDECTOMY: Single lumen endotracheal tube (SLETT) was used of anaesthetic intubation and general inhalational anaesthesia. Operative decubitus was supine with extension and abduction of the ipsilateral arm. Access to mediastinum was obtained by two working ports in the third and fifth intercostal spaces. Mediastinal extension was dissected thoracoscopically and delivered cervically. RESULTS: Out of 1,446 surgical goitres operated during the study period, 72 (5%) had retrosternal goitre. Also, 27/72 (37.5%) cases had posterior mediastinal extension (PME), out of which 11 cases required thoracic approach. We utilised thoracoscopic technique for these 11 cases. The post-operative course was uneventful with no major morbidity. There was one case of recurrent laryngeal nerve (RLN) injury and hoarseness of voice in the third case. Histopathologies in 10 cases were benign, out of which two had subclinical hyperthyroidism. One case had multifocal papillary microcarcinoma. CONCLUSIONS: We opine that novel thoracoscopic technique is a feasibly optimal approach for posterior mediastinal goitre

    Patient: Female, 68 Final Diagnosis: Mediastinal hematoma Symptoms: Agitation • severe hemodynamic instability • severe respiratory distress Medication: — Clinical Procedure: Cardiopulmonary resuscitation • reintubation • thoracic drain Specialty: Surgery Objective: Diagnostic/therapeutic accidents Background: We report a case of surgical central venous port system implantation using Seldinger’s technique with a life-threatening mediastinal hematoma due to the perforation of the superior vena cava. Case Report: A 68-year-old woman was admitted to our institution for port implantation. Open access to the cephalic vein and 2 punctures of the right subclavian vein were unsuccessful. Finally, the port catheter could be placed into the superior vena cava using Seldinger’s technique. As blood aspiration via the port catheter was not possible, fluoroscopy was performed, revealing mediastinal contrast extravasation without contrasting the venous system. A new port system could be placed in the correct position without difficulties. After extubation, the patient presented with severe respiratory distress and required consecutive cardiopulmonary resuscitation and reintubation. The CT scan showed a significant hematoma in the lower neck and posterior mediastinum with tracheal compression. We assumed a perforation of the superior vena cava with the tip of the guidewire using Seldinger’s technique. Long-term intensive treatment with prolonged ventilation and tracheotomy was necessary. The port system had to be subsequently explanted due to infection. Conclusions: Mediastinal hematoma is a rare but life-threatening complication associated with central venous catheterization using Seldinger’s technique. Perforation occurs most often during central venous catheterization in critical care. Mediastinal hematoma is an example of a mechanical complication occurring after central venous catheterization, which has been described only a few times in the literature to

    In 1998, a 68-year-old woman was diagnosed with rheumatoid arthritis. She was treated with prednisolone, nonsteroidal anti-inflammatory drugs, methotrexate (MTX), and biological drugs. Retroperitoneal lymph node swelling and hepatosplenomegaly appeared but spontaneously disappeared after drug withdrawal. Anorexia and general fatigue occurred in March 2012. She was admitted to our hospital with retroperitoneal, periaortic, and mediastinal lymph node swelling and was found to have multiple liver tumors. Based on the results of aspiration biopsy of a liver tumor, she was diagnosed with malignant lymphoma (Hodgkin lymphoma). She died from liver failure and disseminated intravascular coagulation before chemotherapy. We present this case of MTX-associated lymphoproliferative disorder, which caused formation of a liver tumor. PMID:25744928

    Regarding primary mediastinal large B-cell lymphoma (PMLBCL), there are several controversial topics that warrant further investigation: the superiority of third-generation regimens, the impact of rituximab, the use of involved field radiotherapy (RT) and the assessment of clinical response by positron emission tomography (PET). We report our experience on 74 PMLBCL patients treated with a combination of a third-generation chemotherapy regimen (MACOP-B) and rituximab: an observational retrospective single-centre study was conducted on patients diagnosed and treated between February 2002 and July 2011. All patients were evaluated by computed tomography scan and PET scan; after the final PET evaluation, PET-negative patients were observed, whereas PET-positive patients underwent mediastinal RT. Sixty-one (82.4%) patients achieved a complete response after the MACOP-B plus rituximab regimen; 68.9% presented a positive final PET and were treated with local RT, whereas 31.1% had a negative PET. Five patients relapsed within 12 months. At 10 years, overall survival was 82%, progression-free survival was 87.6% and disease-free survival (DFS) was 90.5% (median follow-up 4 years). No statistically significant differences were observed in DFS between the patients treated also with RT (PET positive) and patients only observed (PET negative): 90.7% vs 90% (p = 0.85), respectively. In our experience, adding rituximab does not change the final results in terms of complete response and DFS utilizing third-generation regimen. Furthermore, the introduction of the PET-guided RT approach leads to a patient-tailored treatment, which preserves the outcome and, at the same time, allows reducing the use of RT. PMID:25256959

    Liposarcomas are rare entities and those located in the neck and mediastinum are exceptional. We report the case of a 58 year-old Caucasian male who presented with dysphonia, mild dysphagia to solids, dyspnoea at exertion and cough due to a giant mass of the neck originating from the deep cervical space at C6 vertebral level spreading into the posterior mediastinum. The lesion, that was associated with a right vocal cord palsy, caused severe lateral displacement of the trachea and oesophagus. The case has been managed by complete surgical resection through a combined cervical and thoracic approach associated with a tracheostomy due to the risk of bilateral recurrent nerve dysfunction at the end of the intervention. The tumour was diagnosed as a encapsulated low-grade liposarcoma. Six months after surgery the tracheostomy was closed. At 24 months clinical and radiological follow-up the patient is doing well and disease free. PMID:25837020

    Background: Cervicofacial emphysema may arise due to the leakage of air from a defect in the aerodigestive tract to the fascial layers of neck and face. Rarely, it may be caused by insufflation of air through the Stensen’s duct. Case Report: We present a case with diffuse facial, cervical and mediastinal emphysema due to playing a wind instrument immediately after a facial trauma. There was no mucosal defect or laceration noticed by examination which could explain the origin of the emphysema. Despite the widespread cervicofacial emphysema with mediastinal involvement, the patient significantly improved within 48 hours without any intervention. Conclusion: Even though cervicofacial emphysema ameliorates spontaneously, increased care must be taken, especially when there is pneumomediastinum and/or pneumothorax. PMID:25667794

    The Port-a-cath (PAC) is a catheter totally implanted under the skin. It is commonly used in oncology for permanent venous access. It provides a more simple way to infuse chemotherapies, antibiotics or parenteral nutrition, while offering improved comfort to patients. The usual complications of these devices (infections and catheter obstructions) are well documented. More exceptional events are catheter fractures with systemic migration, and endopleural perfusions due to a wrong positioning of the catheter. Since 1998, 10 cases of mediastinal infusion of cytotoxics have been reported. Surgical management was necessary in only two cases. We are reporting the case of a 57-year-old female suffering from a multimetastatic sigmoid adenocarcinoma. A mediastinal infusion of Folfiri and bevacizumab with a tracheal necrosis complicated the PAC use and required a latissimus dorsi myoplasty to fill up the tracheo-bronchial defect. PMID:21362735

    Bronchogenic cysts are the most common cystic mediastinal lesion in children. Bronchogenic cyst causing unilateral obstructive emphysema is a rare presentation. We report the case of a one and half month old infant who presented with respiratory distress which was initially suspected as left pneumothorax on frontal chest radiograph but was later found to be due to hyperinflated left lung and hence the possibility of congenital lobar emphysema was considered. CT thorax and limited MRI sections revealed a cystic lesion in mediastinum causing obstructive emphysema and mediastinal displacement. He underwent an emergency thoracotomy and excision of the cyst via an extrapleural approach. Post operatively, rapid improvement of the infant was noticed both clinically as well as radiologically. Cross sectional imaging like CT or MR is required for reaching the correct and early diagnosis in paediatric patients with respiratory distress, when there is diagnostic dilemma based on chest radiograph.

    We report two cases of solitary mediastinal lymph node recurrence after colon cancer resection. Both cases had para-aortic lymph node metastasis at the time of initial surgery and received adjuvant chemotherapy for 4 years in case 1 and 18 mo in case 2. The time to recurrence was more than 8 years in both cases. After resection of the recurrent tumor, the patient is doing well with no recurrence for 6 years in case 1 and 4 mo in case 2. Patients should be followed up after colon cancer surgery considering the possibility of solitary mediastinal lymph node recurrence if they had para-aortic node metastasis at the time of initial surgery.

    Mediastinal aneurysms are rare but potentially life-threatening. Among these, bronchial artery aneurysms are most frequently reported, whereas up to now aneurysms of the proper esophageal artery had never been reported. A 69-year-old woman was referred to our hospital for treatment of a massive mediastinal hematoma. Enhanced computed tomography and selective proper esophageal arteriography revealed a 5-mm aneurysm in the proper esophageal artery that arises from the thoracic aorta at the Th8 level and has an anastomotic branch with the bronchial artery peripherally. Transcatheter arterial embolization was successfully performed using a mixture of N-butyl cyanoacrylate and lipiodol (1:3 ratio, 0.3 ml). Post-embolization angiography showed no filling into the aneurysm. The patient recovered with no complications and was discharged on the 25th post-procedure day. PMID:27094689

    A 26-year-old man was admitted because of an abnormal shadow on a chest roentgenogram. Computed tomography(CT) revealed a very large tumor in the anterior mediastinum and bilateral mediastinal lymphadenopathy. Examination of a CT-guided biopsy specimen revealed a yolk-sac tumor. The patient received 4 courses of bleomycin, etoposide, and cisplatin chemotherapy. After chemotherapy, the tumor was markedly reduced in size, but the lymphadenopathy remained. The patient underwent thoracoscopic biopsy of the mediastinal lymph nodes. Sarcoid nodules were found in all the biopsied nodes, and the lymphadenopathy was thought to be a sarcoid-like reaction associated with the germ cell tumor. Resection of the residual tumor was performed according to the treatment algorithm of the International Germ Cell Cancer Collaborative Group. There were no viable tumor cells in the resected tissue. The patient is free of recurrence and without any sign of generalized sarcoidosis 3 years after the surgery. PMID:26066869

    Primary mediastinal B-cell lymphoma (PMBCL) is an uncommon lymphoma for which existing data is limited. We utilized the National Cancer Database (NCDB) to evaluate PMBCL and the impact of radiotherapy (RT) on outcomes in the years following FDA approval of rituximab. We queried the NCDB for patients with PMBCL diagnosed from 2006 to 2011 and treated with multiagent chemotherapy. Kaplan-Meier overall survival (OS) estimates, univariate (UVA), and multivariate (MVA) Cox proportional hazards regression analyses were performed. Propensity score matched analysis (PSMA) was performed to account for indication bias and mitigate heterogeneity between treatment groups. 465 patients were identified with a median follow-up of 36 months. Median age was 36 years; 43% received RT. 5-year OS for the entire cohort was 87%, and for the no-RT and RT groups, 83% versus 93%, respectively. On UVA, OS was improved with RT (HR 0.34, P = 0.002). On MVA, RT remained significantly associated with improved OS (HR 0.44, P = 0.028) while Medicaid insurance status and increasing stage remained significantly associated with OS decrement. PSMA confirmed the OS benefit associated with RT. This analysis is the largest PMBCL dataset to date and demonstrates a significant survival benefit associated with RT in patients receiving multiagent chemotherapy in the rituximab era. More than half of patients treated in the United States during this time period did not receive RT. In the absence of phase III data to support omission, combined modality therapy with its associated survival benefit should be the benchmark against which other therapies are compared. Am. J.

    Postsurgical aspergillosis occurs primarily in immunocompetent patients whose main predisposing factor is the loss of skin and mucosal integrity during surgery. Local infection tends to be destructive and refractory to treatment and relapses are common. It is important to consider aspergillosis in the differential diagnosis of slowly progressive and destructive surgical site infections with negative bacterial cultures. We present the case of a child who developed Aspergillus fumigatus mediastinitis months after heart surgery. PMID:26965883

    Background Endobronchial ultrasound (EBUS)-guided biopsy is the mainstay for investigation of mediastinal lymphadenopathy for laboratory diagnosis of malignancy, sarcoidosis, or TB. However, improved methods for discriminating between TB and sarcoidosis and excluding malignancy are still needed. We sought to evaluate the role of genomewide transcriptional profiling to aid diagnostic processes in this setting. Methods Mediastinal lymph node samples from 88 individuals were obtained by EBUS-guided aspiration for investigation of mediastinal lymphadenopathy and subjected to transcriptional profiling in addition to conventional laboratory assessments. Computational strategies were used to evaluate the potential for using the transcriptome to distinguish between diagnostic categories. Results Molecular signatures associated with granulomas or neoplastic and metastatic processes were clearly discernible in granulomatous and malignant lymph node samples, respectively. Support vector machine (SVM) learning using differentially expressed genes showed excellent sensitivity and specificity profiles in receiver operating characteristic curve analysis with area under curve values > 0.9 for discriminating between granulomatous and nongranulomatous disease, TB and sarcoidosis, and between cancer and reactive lymphadenopathy. A two-step decision tree using SVM to distinguish granulomatous and nongranulomatous disease, then between TB and sarcoidosis in granulomatous cases, and between cancer and reactive lymphadenopathy in nongranulomatous cases, achieved > 90% specificity for each diagnosis and afforded greater sensitivity than existing tests to detect TB and cancer. In some diagnostically ambiguous cases, computational classification predicted granulomatous disease or cancer before pathologic abnormalities were evident. Conclusions Machine learning analysis of transcriptional profiling in mediastinal lymphadenopathy may significantly improve the clinical utility of EBUS

    Colon cancer is the second most common type of cancer in females and the third in males, worldwide. The most common sites of colon cancer metastasis are the regional lymph nodes, liver, lung, bone and brain. In this study, an extremely rare case of colon adenocarcinoma with extensive metastasis to the mediastinal lymph nodes without any other organ involvement is presented. A 44-year-old Caucasian male presented with abdominal pain, a change in bowel habits, melena and weight loss. Colonoscopy revealed a large friable, ulcerated, circumferential mass in the ascending colon. Biopsies were consistent with the diagnosis of invasive moderately differentiated adenocarcinoma. Subsequently, right colon resection was performed, and pathological analysis revealed moderately differentiated adenocarcinoma of the right colon with extensive regional lymph node involvement. Computed tomography (CT) scans of the chest, abdomen and pelvis were performed preoperatively as part of routine staging for colon cancer. No liver or lung pathology was identified; however, multiple pathologically enlarged mediastinal lymph nodes were observed. Endoscopic ultrasound with fine needle aspiration of the largest mediastinal lymph node, which measured 5.2×3.5 cm on CT scans, was performed. The pathology was again consistent with the diagnosis of metastatic colorectal primary adenocarcinoma. At present, no optimum treatment has been identified for metastatic colon cancer to the mediastinal lymph nodes. The patient in the current case received chemotherapy with folinic acid, fluorouracil and oxaliplatin (FOLFOX), as well as with bevacizumab. Initial follow-up CT scans of the chest revealed a positive response to treatment. Physicians, in particular, radiologists, must consider the mediastinum during the first evaluation and further follow-up of patients with colorectal carcinoma even in the absence of metastasis.

    Malignant melanoma is the third most common tumour to cause cerebral metastases, following breast and lung cancer. Central nervous system metastases occur in 10-40% of patients with melanoma. Intracranial metastasis from a primary malignant melanoma of the anterior mediastinum is uncommon. We report a case of solitary intracranial metastatic melanoma arising from a primary mediastinal tumour. We then discuss the clinico-radiological features and treatment options. PMID:27145991

    Primary mediastinal choriocarcinoma is a rare malignancy that is characterized by multiple metastases at the time of diagnosis, poor response to therapy and short survival times. There is no standard treatment for this disease. The present study described the case of a 25-year-old man with metastatic mediastinal choriocarcinoma. The patient completed 8 cycles of standard combination chemotherapy consisting of etoposide [100 mg/m2; intravenous (IV) drip on days 1–3], cisplatin (20 mg/m2; IV drip on days 1–5) and bleomycin (20 mg/m2; intramuscular injection on days 1, 8 and 15 every 21 days). The α-fetoprotein level decreased to 2.36 ng/ml, the serum β-human chorionic gonadotropin (β-HCG) level markedly decreased to 8.69 IU/l, which was slightly higher than the normal upper limit, and the lactate dehydrogenase level decreased to a normal range. The computed tomography (CT) scan revealed that the number and size of the lung lesions was significantly reduced subsequent to 8 cycles of chemotherapy and the size of the mediastinal tumor was evidently reduced, with a less solid component and a more cystic component. The response assessment indicated partial remission. Following chemotherapy, a radiation dose of 50 Gy (2.0 Gy/fraction) was administered to the involved field of the mediastinum. Following radiotherapy, the β-HCG level had also decreased to normal levels, and CT evaluation revealed that the size of the residual lung lesions demonstrated no evident change, and the mediastinal tumor was slightly reduced in size, with a less solid component. The patient refused to undergo surgery and did not receive additional treatment following radiotherapy. At present, the patient has survived >16 months of follow-up without any symptoms.

    We report a novel surgical strategy for the resection of a rare type of posterior mediastinal tumour in a young patient. A melanotic schwannoma arose from the left thoracic sympathetic chain, adjacent to the origin of the artery of Adamkiewicz. Successful excision of this tumour via a minimally invasive approach without arterial or spinal cord injury was possible with the aid of neurological monitoring using spinal-evoked potentials.

    Positron emission tomography with computed tomography (PET–CT) is an integral part of oncology practice in the current-day scenario. The hybrid anatomical and metabolic imaging information in this imaging modality provides access to a wealth of incidental findings which can have implications in the management of the patient, especially when surgical options are being considered. In this pictorial essay, we present incidentally detected mediastinal vascular anomalies on PET–CT, along with a review of associated literature. PMID:25883859

    The utility of computed tomography (CT) in evaluation of mediastinal abnormalities was assessed in 23 pediatric patients. By comparison with standard chest radiography, CT provided additional diagnostic information in 82% of the patients. In 65%, the CT findings contributed to a change in clinical management. CT was most useful in documenting a benign process (near-water-density mass or a normal vascular or soft-tissue structure) and in demonstrating the full extent of a malignant tumor.

    BACKGROUND Myelomatous pleural effusion (MPE) is a rare occurrence in patients with multiple myeloma (MM). Fewer than 20 cases of MPE have been reported as an initial manifestation of MM. Extramedullary plasmacytoma (EMP) occurs in fewer than 5% patients with MM, and mediastinal EMP is even rarer, with only about 80 cases reported in the literature. We present a case study involving a patient with concurrent MPE and mediastinal EMP as an initial manifestation of MM. CASE REPORT The patient was a 74-year-old nonsmoking female with a 3-month history of exertional dyspnea and back pain. On exam, the patient was afebrile (temperature 37.2°C), blood pressure was 160/74 mm Hg, heart rate was 92 bpm, respiratory rate was 22/min, and oxygen saturation was 87% on room air. Patient was in mild distress and had decreased breath sounds over right lung fields about halfway up with dullness to percussion. Computed tomography of the chest showed a moderate-sized right pleural effusion and an anterior mediastinal mass. Thoracentesis showed a lymphocyte-predominant exudate. Cytology showed numerous plasma cells including immature forms. Stains for CD138 were positive, confirming plasma cell origin of cells. The anterior mediastinal mass was also biopsied and showed diffuse infiltrate of lymphocytes with plasma cell features that were also positive for CD138. Systemic protein electrophoresis showed a monoclonal immunoglobulin G kappa spike, and bone marrow biopsy was consistent with MM. CONCLUSIONS MPE and EMP are extremely rare manifestations in MM. In addition, it is extremely rare for these to be the presenting features of MM. We report concurrently occurring MPE and EMP in a patient as her initial manifestation of MM. PMID:27396960
