Multiple pancreatic pseudocyst disease.

In an effort to determine the incidence of multiple pseudocyst disease and establish the optimal approach to this problem, the records of 91 consecutive patients diagnosed during a 36-month period as having pancreatic pseudocyst disease by sonography or computerized tomographic scanning were reviewed. Thirteen patients (14.3%) had multiple cysts; all received sonograms and six had CT scans.

Radiological manifestations of Strongyloides stercoralis.

Nine patients with radiological changes due to Strongyloides stercoralis (SS) are described. A wide variation in appearance exists ranging from mild edema of the duodenal and small bowel mucosa to grossly enlarged, prominent valvulae conniventes. Small bowel dilatation is significant, and in overwhelming infestation toxic dilatation with paresis results.

Upper esophageal varices: report of three cases and review of the literature.

Cervical esophageal varices occur rarely. Although cases of primary upper esophageal varices have been reported, the most frequent underlying etiology is superior vena cava obstruction. Usually asymptomatic, cervical esophageal varices may occasionally be responsible for significant gastrointestinal hemorrhage.

Local duodenal metastasis from colonic carcinoma.

The clinical and radiologic appearance of an isolated metastasis to the duodenum may mimic a primary pancreatic or duodenal cancer. As lymphatics from the right colon drain to periduodenal lymph nodes, lymphatic spread from right colon cancer can cause enlargement of the duodenal loop, with ulceration or distortion of the mucosa on the medial aspect of the duodenum. We present three patients with ulcerating metastases in the duodenum from colon cancer whose cases exemplify the problems of diagnosis and management.

Kaposi's sarcoma of the intestinal tract: roentgen manifestations.

Five cases of generalized Kaposi's sarcoma are reported with roentgen evidence of involvement of the intestinal tract. In three instances, there was extensive involvement of the small bowel with multiple intramural nodules. The fourth patient demonstrated multiple polypoid lesions of the colon, and in the fifth a constricting lesion of the ileum was present.

Unusual pelvic complications of a pancreatic pseudocyst.

Pancreatic pseudocysts are notorious for their extension beyond the normal confines of the pancreatic bed. Their inferior extension has been known to involve kidney and ureter. However, involvement of the bladder and rectum is unique although understandable on anatomic grounds.

Colonic necrosis complicating pancreatitis.

Bowel necrosis is an uncommon complication of pancreatitis. Two patients are reported who developed ileocecal and descending colon changes as a result of ischemia following severe pancreatitis. Arteriography in one patient confirmed the presence of intraluminal thrombi.

Pancreatic pseudocysts involving the spleen.

Pancreatic pseudocyst involving the splenic parenchyma itself is an unusual complication of pancreatitis. The diagnosis is best established by arteriography, isotopic studies, and sonography. Once confirmed, surgical intervention is mandatory because of the danger of secondary hemorrhage.

Pneumoperitoneum and appendicitis.

Pneumoperitoneum was observed in five patients with acute perforative appendicitis (APA). In each case this radiographic observation led to an incorrect diagnosis. Free intraperitoneal gas is found in a small number of patients with APA and has no apparent effect on the course or prognosis of the disease.

Leiomyoblastoma of the stomach. Report of 9 cases.

Gastric leiomyoblastoma is a rare intramural tumor which originates in the smooth muscle. Nine cases were studied with respect to their clinical, radiological, and pathological features. Six distinct radiological patterns may be seen, of which 5 are represented in this series.
