Based on metaiodobenzylguanidine (MIBG) scintigraphy, magnetic resonance imaging and blood tests, preoperative diagnosis was adrenal pheochromocytoma. En-bloc resection of the tumor and the right kidney was performed. ...

Sarcomas of the breast constitutes <1% of primary malignant breast tumors. Liposarcoma of the breast represents 3-24% of the primary breast sarcomas. Liposarcoma can arise from pre-existing benign lesions like fibroadenoma or from lipoid tissue in the breast. There are only few cases of liposarcoma of the breast in young females reported in the literature. Liposarcoma of the breast typically ...

The spectrum of causes of hepatic gas detected at computed tomography (CT) and ultrasonography (US) is widening. There are many iatrogenic and noniatrogenic causes of hepatic parenchymal, biliary, hepatic venous, and portal venous gas. Hepatic gas may be an indicator of serious acute disease (infarct, infection, ...

A 70-year-old man with diabetes mellitus seen for fever, right chest pain, and right-lung field consolidation on chest X-ray was found in thoracoabdominal computed tomography (CT) to have variable-sized nodules in both lung fields and multiple low-density hepatic areas. On physical examination, his pulse was 145 beats per minute and blood pressure 92/68mmHg, indicating a ...

The protozoan parasite Entamoeba histolytica is the causative agent of amoebiasis, a human disease characterized by dysentery and liver abscess. The physiopathology of hepatic lesions can be satisfactorily reproduced in the hamster animal model by the administration of trophozoites through the portal vein route. Hamsters were infected with radioactively ...

Opens surgical drainage of intraabdominal, intrahepatic, and mediastinal abscess is well established. Although this may be the procedure of choice when there are indications for treatment of concurrent intraabdominal and mediastinal surgical disease, with the advent of computerized axial tomography and ultrasonography we have identified a patient population best served by ...

A liver abscess may arise following any insult to gut integrity allowing portal drainage of bacteria to hepatocytes. Foreign bodies such as bones, toothpicks and items of stationery have previously been implicated in compromising gut epithelium. Here we present the case of a 57 year old man suffering from a left liver abscess. This was defined on CT which ...

From 58th scientific assembly and annual meeting of the Radiological Society of North America; Chicago, IL (26 Nov 1972). Additional information can be obtained by imaging the liver repeatedly during the first two minutes after intravenous injection of a bolus of /sup 99m/Tc-sulfur colloid. This study is referred to as hepatic scintiangiography and depicts arterial ...

Tertiary syphilis, especially in cases involving visceral gummatous disease, can be confused with cancer of the solid organs. We report a case of tertiary hepatic syphilis that manifested with intrahepatic masses in a patient who had an underlying primary peritoneal serous carcinoma (PPSC). The patient was diagnosed with PPSC and achieved a complete remission of PPSC following ...

The purpose of the present paper was to analyse the association between sequences of Entamoeba histolytica and their relationship with the development of hepatic abscesses in hamsters, using a complementary DNA library for E. histolytica. From the sequences obtained, we designed oligonucleotides for amplification by PCR. Trophozoites were isolated from ...

We report a rare case of two communicating pseudoaneurysms of the common hepatic artery 1 month postoperatively following pylorus-preserving pancreaticoduodenectomy due an abscess formation. We describe the superselective transcatheteral embolization technique with deployment of interlocking detachable coils and Histoacryl-Lipiodol in this case and discuss ...

The authors have encountered benign liver masses as frequently as malignant lesions in children with hepatomegaly. Lesions studied included abscesses, cavernous hemangioma/hemangioendothelioma, adenoma of glycogen storage disease, choledochal cysts, focal nodular hyperplasia, cystic hepatoblastoma, and hamartoma. An intergrated imaging protocol involving ultrasound, computed ...

A case of actinomycosis involving the liver is reported. The liver scan with /sup 99m/TcS colloid showed multiple areas of focal abnormalities. The /sup 67/Ga citrate liver scan showed these areas to concentrate intensely. This pattern of differential hepatic scintigraphy is seen in pyogenic abscesses as well as malignancy of the liver. Actinomycosis may ...

A description is given of the parallel use of a vascular or blood pool radioactive tracer to assess the vascular content of a lesion relative to surrounding the healthy liver by comparing its amplitude or contrast on both reticuloendothelial and vascular scans. The scan discrimination between relatively vascular lesions and avascular processes such as cysts and ...

Tuberculosis of the liver in association with generalized miliary tuberculosis is not an uncommon clinical entity. A solitary tuberculous liver abscess, however, is rare. Two such cases, in which there was no clinical evidence of extrahepatic tuberculosis, are reported. The similarities between this condition and other causes of hepatic lesions are ...

A 68 year old diabetic man developed septicaemia and multiple liver abscesses due to Streptococcus intermedius. Liver biopsy revealed streptococcal botryomycosis which showed the Splendore-Hoeppli phenomenon. Diabetes mellitus is an example of the immunosuppressed states that have been associated with botryomycosis.Images

Despite reports to the contrary, unobstructed drainage of 50% of an otherwise normal liver through either the right or left uninfected hepatic duct is adequate to restore normal liver function, even if the obstructed lobe remains in place. An undrained liver lobe, if present, may require no further treatment. As long as it is completely obstructed and uninfected, it will ...

The complications of amebic liver abscess (ALA) are underappreciated in developed countries, and are often misdiagnosed. We report a 16 month-old with ALA, initially misdiagnosed with pneumonia, who became critically ill with peritoneal, pleural and pericardial extension, and gastric perforation. In addition to highlighting the complications of ALA, this case demonstrates the ...

The aim of undertaking was, to promote in-vitro measuring techniques as well as in-vivo measurements of organs using imaging techniques. Se-75 and In-113 have equal ability to prove the presence of abscesses or cysts. For the detection of tumors their use...

A case of Chromobacterium violaceum infection in a patient who apparently acquired the infection from the water of a Florida river is described. In addition to the usual presentation of sepsis, hepatic abscesses, and pustular dermatits, the patient presented as an acute abdominal emergency. Although most reported cases have been fatal, this patient ...

A 9-year-old Quarter horse was presented for chronic refractory pneumonia. On necropsy, an hepatic abscess, caudal vena cava thrombosis, pulmonary thromboembolism, and embolic pneumonia were identified. Similar lesions have been reported in cattle as caudal vena cava thrombosis syndrome, however this syndrome has not previously been reported in horses.

We describe a case of epidural thoracic abscess presenting similar to epidural lymphoma on imaging and review the imaging findings and clinical characteristics of both to help differentiate the two. Typical magnetic resonance imaging characteristics for epidural abscess are a heterogeneously enhancing epidural collection, which is isointense/hypointense on ...

IntroductionMeckel's diverticulum is a common congenital anomaly of the gastrointestinal tract, but is an uncommon cause of serious complications in adults. Although cases of patients with hemorrhage, bowel obstruction or perforation associated with Meckel's diverticulum have been reported, there have been no prior reports of patients with combined urinary and bowel obstruction due to ...

We present a rare case of a focal intrahepatic extramedullary hematopoiesis (EMH) that mimicked a hypervascular hepatic neoplasm in a 33-year-old woman with idiopathic myelofibrosis. The lesion showed homogeneous and persistent enhancement on both contrast-enhanced CT and gadolinium-enhanced dynamic MR imaging. The lesion did not demonstrate an apparent ...

Because of the high diagnostic yield, its widespread availability and the possibility of bedside examinations, US has become the imaging modality of choice in patients with acute right upper quadrant pain caused by inflammatory disorders such as liver abscesses, acute cholangitis and acute cholecystitis. Computed tomography (CT) can be reserved for more complex cases. US, ...
