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. The combined false negative and false positive rate with sonography was 9%. Spontaneous resolution occurred involving five cysts (18%) up to 6.5 cm in size. The diagnosis of cyst multiplicity was confirmed at operation in seven cases; two of the seven operations were excisional and the remaining patients received drainage procedures. There were no operative deaths; complications included one patient who required chronic enzyme replacement therapy after excision and another patient who developed a subphrenic abscess after attempted percutaneous drainage. The incidence of multiple pseudocyst disease in our series is just over 14%. The possibility of multiplicity should be carefully investigated in each patient with pseudocyst disease. In light of the rate of spontaneous resolution, not all patients with multiple pseudocysts may require operative therapy. Because of the 7.7% false negative diagnoses with sonography, CT scanning is especially helpful when the diagnosis of multiple pseudocysts is suspected or in preoperative preparation of pseudocyst drainage. If an operation becomes necessary, a drainage procedure rather than excision should be used whenever possible to maximize gland salvage.

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. Spasm, ulceration, and stricture are encountered in addition. The appearances usually improve and reverse with treatment. Ampullary involvement is responsible for reflux of barium into the pancreatic duct and biliary tree through a patulous sphincter. In 1 patient the colonic changes resembled ulcerative colitis.

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. Twenty-five cases of upper esophageal varices have been described in the literature to date. Three additional cases are presented and the previous literature is reviewed. Potential collateral pathways in the presence of superior vena cava obstruction are discussed.

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. Two patients with small bowel involvement had significant malabsorption. This latter complication of diffuse Kaposi's sarcoma of the small bowel has not been previously reported. The diagnosis of the nature of the roentgen intestinal abnormality can usually be made, because intestinal involvement generally occurs late in the disease, when both extensive cutaneous nodules and edema of the extremities are apparent.

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. We report an enormous pseudocyst with extension deep into the pelvis to displace both rectum and bladder.

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. Most such lesions occur in the gastric antrum. Leiomyoblastomas are generally benign and do not recur following removal.
