Traumatic neuroma of the intestine.

A traumatic neuroma of the intestine arising at the site of a previous ileocolic anastomosis is reported. Barium enema examination showed an extramucosal mass in a patient who presented with abdominal pain, rectal bleeding, and anemia. Although rare, traumatic neuroma should be included in the differential diagnosis of an intestinal mass occurring after intestinal surgery.

Real-time sonography in suspected acute cholecystitis. Prospective evaluation of primary and secondary signs.

Sonographic findings in 497 patients with suspected acute cholecystitis were analyzed prospectively. Combined use of primary and secondary sonographic signs led to excellent positive and negative predictive values. Positive predictive values for stones combined with either a positive sonographic Murphy sign (92.2%) or with gallbladder wall thickening (95.2%) were excellent for acute cholecystitis. Positive predictive value of these signs for patients requiring cholecystectomy was even higher (99.0%). Negative predictive values for combined use of primary and secondary signs to exclude acute cholecystitis were also excellent (95.0% for no stones and negative sonographic Murphy sign). Real-time sonography alone, using both primary and secondary signs, can be definitive in nearly 80% of patients with suspected acute cholecystitis. These patients require no further imaging evaluation. Sonography should be the screening test of choice in acute cholecystitis because it is cost effective, prospectively highly accurate, quick, and better at characterizing and detecting other abdominal lesions than cholescintigraphy. A proposed algorithm is described.

Colonic malacoplakia.

Malacoplakia is an uncommon, pathologically distinct, granulomatous disease most frequently found in the urinary tract. Malacoplakia of the colon may cause abdominal pain, diarrhea, rectal bleeding, and fever. Radiographic features are variable and include polyps, bulky masses, mucosal ulcerations, and fistulae.

Retroperitoneal malacoplakia.

Malacoplakia is an uncommon, pathologically distinct, granulomatous disease that occurs most frequently in the urinary tract. It can present as an abdominal mass in a patient with urinary tract infection. A case of retroperitoneal malacoplakia with CT findings and successful treatment with radiation therapy is presented.

Computed tomography of Sipple syndrome.

The computed tomographic (CT) findings of pheochromocytoma, adrenal medullary hyperplasia, and medullary thyroid carcinoma in a patient with Sipple syndrome are presented. The CT finding of diffuse enlargement of one or both adrenal glands in a patient with clinical and laboratory evidence of pheochromocytoma should raise the suspicion of adrenal medullary hyperplasia and Sipple syndrome.

Burkitt lymphoma in acquired immune deficiency syndrome.

An unusual case of Burkitt lymphoma presenting with an osteolytic pelvic lesion in a homosexual man with acquired immune deficiency syndrome (AIDS) is reported. Computed tomography (CT) demonstrated unsuspected renal involvement and was used for guided percutaneous biopsy. The CT appearance of renal Burkitt lymphoma was similar to that of other types of renal lymphoma.

Patterns of resolution in successfully treated hepatic amebic abscess: sonographic evaluation.

Gray-scale sonography has provided a means of following cases of successfully treated hepatic amebic abscess, allowing new insights into the natural history of this entity. In this study the majority of cases (23 of 32) resolved over a variable time period (1.5-23 months, median 7 months) to a normal sonographic hepatic parenchymal pattern. It is important that the transient, persistent abnormality seen after successful treatment not prompt reinstitution of therapy or further diagnostic testing in these patients. A smaller subgroup (six of 32) had sonographically persistent residua that appeared identical to benign simple cysts of the liver. The remaining three lesions showed slightly increased or decreased hepatic echogenicity after treatment.

Hereditary generalized juvenile polyposis: association with arteriovenous malformations and risk of malignancy.

A young man with hereditary juvenile polyposis, a duodenal adenoma with carcinoma in situ, and multiple arteriovenous malformations of the lungs and liver is reported. Because of the risk of malignancy, it is suggested that patients with juvenile polyposis have endoscopic or radiographic surveillance of the upper gastrointestinal tract in addition to either prophylactic colectomy or regular colonoscopic surveillance with polypectomy. In view of the serious potential complications of associated pulmonary, cerebral, and hepatic arteriovenous malformations, screening of patients with juvenile polyposis with chest radiography, magnetic resonance imaging of the brain, and sonography of the liver may be warranted.

Computed tomography in endobronchial neoplasms.

Computed tomography (CT) was performed in 86 patients with bronchoscopically proven endobronchial neoplasms. There were 76 primary and 10 metastatic lesions. CT correctly identified the abnormal airway in 95% of cases (82/86) by demonstrating either nodule, mass, or stricture. A discrete endobronchial nodule was seen in 55% (47/86). There was good morphological correlation of CT with bronchoscopic findings (89% for discrete nodule, 80% overall). Appropriate atelectasis was noted in 80% (69/86) of cases. CT is sensitive in detecting and localizing endobronchial neoplasms and correlates well with bronchoscopic findings.

Cholecystoduodenal fistula due to pancreatic carcinoma: CT diagnosis.

Spontaneous biliary-enteric fistula is almost always due to cholelithiasis or peptic ulcer disease; rarely is malignancy responsible. A patient with carcinoma of the pancreas who presented with gastrointestinal hemorrhage and pneumobilia due to a malignant cholecystoduodenal fistula is reported.

Computed tomography of benign cystic teratoma of the omentum.

Benign cystic teratoma of the omentum is a rare gynecologic condition. No cases have been diagnosed preoperatively; six cases have been reported in association with an ovarian teratoma. We report a seventh case in which ultrasound and CT were used preoperatively.

CT features of hemorrhagic malignant liver tumors.

Hemorrhage is a recognized occurrence in hepatocellular carcinoma but is infrequently seen with tumors metastatic to the liver. This complication was observed in three patients with primary hepatic malignancy and in four patients with hepatic metastases (melanoma, two; colon, one; breast, one) who were studied by CT. Hemorrhage occurred in the patient with metastatic colon carcinoma in the setting of anticoagulation. Definitive radiographic signs of hemorrhage were detected by CT in six of the patients, including hyperdense hepatic masses on noncontrast scans (four patients), high density peritoneal (one patient) and subcapsular fluid (one patient), and the hematocrit effect in peritoneal fluid (one patient). In three patients an irregular liver border adjacent to perihepatic fluid suggested the liver as the organ from which bleeding originated. There were four deaths, none of which was immediately related to the hemorrhagic complication.
