AbstractTeratomas are neoplasms of embryonal origin in domestic animals and are generally associated with reproductive organs. We report a case of teratoma involving the right kidney in a young llama that presented clinically with signs of mild colic and constipation.

This case describes a contiguous mediastinal and retroperitoneal mature teratoma in a congenital diaphragmatic defect, a combination that is hitherto unreported in literature. It substantiates embryological chronology of events during the cephalad migration of the primordial germ cells through the developing diaphragm, prior to its closure. PMID:20140770

N-methyl-D-aspartate receptor (NMDAR) encephalitis is a life-threatening paraneoplastic neuropsychiatric encephalitis that predominantly affects young women and has a strong association with ovarian teratomas. Removal of the ovarian teratomas improves the prognosis and decreases the risk of recurrence. We present an 11-year-old girl with NMDAR encephalitis ...

A 4-yr-old striped skunk (Mephitis mephitis) developed an 11- x 7- x 7-cm retroperitoneal mass caudal to the left kidney. The mass was surgically excised and, on the basis of histology and immunohistochemistry, diagnosed as a benign teratoma. Six months later, a second histologically similar neoplasm was excised from the same location and was considered to represent local ...

Patients with functioning renal transplant who develop abdominal aortic aneurysm can safely be treated with endovascular repair. Endovascular repair of aneurysm avoids renal ischemia associated with cross-clamping of aorta.

Gastroschisis is the herniation of abdominal viscera through a paramedian abdominal wall fusion defect without involvement of the umbilical cord. Evisceration usually contains intestinal loops and has no surrounding membrane. Rarely, herniation of other major viscera such as stomach and liver occurs, which makes the prognosis worse. Gastroschisis is ...

A 37-year-old postpartum woman was presented with abdominal pain supposed to be caused by uterine involution or puerperal endometritis after vaginal delivery. During the pregnancy, she was suspected to have a subserosal myoma by ultrasound examination. The pain was finally revealed to be originated from the chemical peritonitis caused by the rupture of the mature cystic ...

Hypertension secondary to stenosis of the left renal artery developed in a thirteen-year-old male six years after completion of inverted Y irradiation (3,600 rad) for abdominal Hodgkin disease. Surgical treatment with nephrectomy resulted in control of the hypertension without the use of antihypertensive agents. We review the literature for this unusual ...

The huge tumor was filled with necrotic and fatty tissue and coagula accompanied with ...

A 14-year-old girl had an abdominal mass with the characteristics of an ovarian germ cell tumor on computed tomography scan.

A 65-year-old man with adult polycystic kidney disease (APKD) and chronic renal failure suffered from intractable abdominal pain and distension for 2 weeks. Meperidine infusion did not alleviate his pain. However, pain and abdominal distension were successfully controlled by embolization of both renal arteries.

Abdominal aortic aneurysm (AAA) repair in the presence of a kidney transplant can be extremely challenging, as it carries significant risks of renal ischemia. Endovascular repair is an attractive option, as it can be performed with little or no impairment of renal arterial flow. We describe the endovascular management of a recurrent ...

We collected 24 brown rats, Rattus norvegicus, in Kanagawa Prefecture in Japan and found one rat harboring a dioctophymatid nematode. A single male and a female worm were recovered from the abdominal cavity and were identified as Dioctophyme renale based on morphologic features and a BLAST DNA sequence analysis. We describe the morphological features of ...

The patient experienced severe unilateral flank pain. Enhanced abdominal computed axial tomography scan showed renal infarction, ...

Owing to an increased use of diagnostic imaging for evaluating patients with other abdominal conditions, incidentally discovered kidney masses now account for a majority of renal tumors. Renal ablative therapy is assuming a more important role in patients with borderline renal impairment. Renal ...

Growing teratoma is still an often unsolved problem especially in male with mixed malignant GCTs of the testis or the mediastinum. This specific situation with progressive tumor growth and simultaneous normalization of tumor markers during or after treatment of malignant GCTs with teratomatous elements is judged as a fatal situation if this situation can not be controlled by ...

CVD and CKD are closely related, and diagnosis/treatment of CVD while considering renal function are ...

Ovarian teratomas are the most common germ cell neoplasm. Subtypes of teratoma include mature cystic, immature and the monodermal teratomas. The benign cystic teratoma shows typical imaging manifestations and can be complicated by torsion, rupture and uncommonly malignant degeneration. Uncommon subtypes of ...

Once considered mostly a postsurgical condition, intra-abdominal hypertension (IAH) and the abdominal compartment syndrome (ACS) are now thought to increase morbidity and mortality in many patients receiving medical or surgical intensive care. Animal data and human observational studies indicate that oliguria and acute kidney injury are early and frequent ...

We present the case of a 25-year-old male who came to the emergency room for pain and abdominal distension following trauma to the mesogastrium. A CT scan was performed, revealing a voluminous retroperitoneal hematoma with laceration of both inferior renal poles with regard to rupture of the isthmus of a horseshoe kidney. The patient presented anemization ...

A communicating vein between the left renal vein and the left ascending lumbar vein has only rarely been reported in the imaging literature. There are very few reports of varicosity of this communicating vein. Nonetheless, awareness about this communicating vein is of utmost importance for surgeons performing aortoiliac surgeries and nephrectomies as it may pose technical ...

Renal lymphangiomatosis is an exceedingly rare disorder characterized by developmental malformation of the lymphatic system surrounding the kidneys. We report a case of bilateral renal lymphangiomatosis in a 21-year-old man who underwent abdominal sonographic examination that revealed numerous cystic areas of various sizes around both ...

The association of a retroaortic left renal vein and an abdominal aortic aneurysm (AAA) fistula is an infrequent event. We present two cases of AAA rupture into the retroaortic left renal vein.

They are rarely symptomatic; however, they can be a cause of life-threatening hematuria. Discussed is the case of a ...

Late colonic metastasis following curative surgery for renal cell carcinoma has rarely been described. We present the first reported case of solitary colonic renal cell carcinoma metastasis presenting as an intra-abdominal bleed, nine years post-nephrectomy.

Traumatic occlusion of the renal artery is a serious injury. Management differs according to the grade of injury. In most circumstances, emergency surgical revascularization or endovascular intervention is required. We describe the case of a child with multiorgan injuries and spasm of the main renal artery after blunt trauma simulating arterial occlusion ...

A 33-year-old man had clinical features of a right renal abscess. Results of excretory urography and ultrasonography showed a focal complex mass lesion in the right kidney.
