Suppurative pylephlebitis and pylethrombosis: the role of anticoagulation.

Suppurative thrombophlebitis of the portal vein resulting from inflammatory intra-abdominal conditions is a rare complication that may result in pylethrombosis and portal hypertension. A case is presented with documented pylethrombosis caused by diverticulitis. Color flow Doppler scanning was used to establish the diagnosis. Systemic anticoagulation therapy was added to the antibiotic regimen because of postoperative propagation of the clot. Anticoagulation therapy prompted resolution of the episode. Long-term follow-up studies demonstrated recanalization of the portal vein. Anticoagulation should be instituted with documented acute pylethrombosis caused by inflammatory disease of the abdomen.

Multiple retroperitoneal schwannomas: case report and review of the literature.

We report a rare case of multiple retroperitoneal schwannomas, initially believed to be an adrenal carcinoma with metastasis. These benign tumors were discovered in a patient presenting with vague back pain. Preoperative radiographic and endocrine evaluations suggested a nonfunctioning adrenal tumor. The final diagnosis and its juxta-adrenal origin were confirmed by histological and immunohistochemical studies. A review of the literature on retroperitoneal schwannoma is included.

Computerized tomographic appearance of hernias of the bladder.

Herniation of the bladder is not uncommon and it can occur with any type of hernia in the groin. Most bladder hernias are discovered unexpectedly during herniorrhaphy, and serious complications can result from intraoperative injury to the bladder. The appearance of hernias on excretory urography and cystography has been described extensively but experience with computerized tomography (CT) has been limited. We describe the appearance of 8 bladder hernias on CT: 2 incisional, 2 femoral, 3 small direct inguinal, and 1 massive direct inguinal hernia with bladder necrosis and perforation. Appearance on CT is characteristic, and this modality may be useful for preoperative evaluation.

Is magnetic resonance imaging alone accurate enough in staging renal cell carcinoma?

A patient with renal cell carcinoma extending into the inferior vena cava presented to our institution. Magnetic resonance imaging demonstrated the superior extent of the thrombus to be at the level of the hepatic veins. Preoperative venacavography showed extension into the right atrium. The need for both studies in evaluating patients with Stage 3A disease is reviewed.

Computed tomographic findings of giant intestinal pseudopolyposis.

The cases of 3 patients with giant intestinal pseudopolyposis are presented. Giant pseudopolyposis complicated chronic ulcerative colitis in 2 patients and granulomatous colitis in 1 patient. Each patient was evaluated with either barium or Gastrografin enema as well as with computed tomography (CT) after administration of oral contrast material. The unique manifestations of this unusual lesion as demonstrated by computed tomography are described.

Renal infarction: computerized tomographic appearance with angiographic correlation.

The clinical diagnosis of renal infarction can be difficult to make and the computerized tomographic appearance can be misleading at times. The different computerized tomographic images can be explained angiographically by the arrangement of the vascular planes of the kidney and by the particular branches that are occluded. We report 2 cases with different angiographic and computerized tomographic appearance to document this correlation.

Computed tomography of intrathoracic kidney.

We report a case of congenital intrathoracic kidney, a rare developmental anomaly, which may present as an asymptomatic posterior mediastinal mass. The evaluation of such lesions can be performed expeditiously with computed tomography and obviate the need for any further clinical studies or operation.

CT appearance of adult intussusception.

A computed tomographic evaluation of adult ileocolic intussusception secondary to polypoid adenocarcinoma is presented. The observed tapering homogeneous peripheral mantle and mixed density core may be characteristic for this entity.

CT appearance of afferent loop obstruction.

Obstruction of the afferent loop may develop in patients who have had a Billroth type II gastrojejunostomy. This obstructed loop has a characteristic but initially confusing computed tomographic appearance that might be mistaken for multiple peripancreatic cystic masses. Three cases of afferent loop obstruction due to gastric carcinoma are reported. In each case, the length of the jejunal segment incorporated into the afferent loop determined the number of cystic masses evident at each scan level. Recognition of the typical anatomic configuration and uniform size of these cystic masses is key to the correct diagnosis.

The choledochocele: correlation of radiological, clinical and pathological findings.

Two cases of choledochocele are presented and 14 cases in the literature reviewed. Choledochocele is defined as a herniation of the common bile duct into the duodenum. This entity is distinguishable radiographically from duodenal diverticulum and duodenal duplication cyst by filling during cholangiography but not during upper gastrointestinal series. The duodenal diverticulum fills on upper gastrointestinal series but not on cholangiography. The duplication cyst will not fill with either method.
