Cytomegalovirus gastritis: protean radiologic features.

Infection with cytomegalovirus (CMV) is a major feature of acquired immunodeficiency syndrome (AIDS). Gastrointestinal involvement is being seen more frequently. Our collective experience involves nine patients with stomach involvement. Seven patients were intravenous drug abusers or homosexuals with AIDS. One developed CMV gastritis as a complication of leukemia and one patient was a West African with lymphoma and human immunodeficiency virus (HIV) infection. All our patients had biopsy-proven CMV inclusion bodies. The radiographic appearances varied widely. The findings included markedly thickened edematous folds, erosive gastritis with aphthous ulceration, and superficial and deep ulceration. One patient had deep ulceration with fistula formation. Computed tomographic (CT) scans confirmed the greatly thickened gastric wall and coarsened folds in two patients. Associated gastrointestinal infections included candida and herpes, and, in addition, pneumocystis carinii pneumonia (PCP) was present in two patients. CMV gastritis may mimic several other conditions including erosive gastritis, peptic ulceration, lymphoma, and carcinoma. It should be strongly considered in immunosuppressed patients.

Gastric duplication cyst communicating with the pancreatic duct: a rare cause of recurrent abdominal pain.

A 41-year-old woman with recurrent attacks of postprandial abdominal pain was found on endoscopic retrograde cholangiopancreatography and subsequent computed tomographic scan to have an enteric duplication within the substance of the pancreas with communication to the pancreatic duct. Celiotomy demonstrated a noncontiguous gastric duplication cyst. Internal drainage was curative.

The forgotten surgical foreign body.

Instruments and drains left in the abdomen following surgery may be responsible for bizarre and varied complications. The patient may remain asymptomatic for months or even years. Complications include adhesion formation, intestinal obstruction, abscesses, and erosion into the gastrointestinal tract. We report 3 patients in whom retained surgical material eroded into the duodenum and colon, respectively, and produced unusual radiologic findings and complications.

Solid and papillary epithelial pancreatic neoplasm: an unusual tumor.

Solid and papillary epithelial neoplasms of the pancreas are uncommon. These grow to a large size, are often palpable, and occur most often in young black women. The tumors have a characteristic histologic appearance and a low malignant potential. Heavy tumor calcification is an unusual finding. Two cases with radiologic-pathologic correlation are presented herein.

Ileal leiomyosarcoma and leiomyoma. False-positive scintiscans for Meckel's diverticulum.

Two cases of ileal leiomyomatous neoplasms with positive scintigraphic findings for Meckel's diverticulum are presented. The precise mechanism for the abnormal concentration of the Tc-99m pertechnetate is uncertain. Illustrations of the collating barium and computerized tomographic studies are included and the scanning technique utilized is reviewed.

Focal esophageal candidiasis in acquired immunodeficiency syndrome (AIDS).

When candidiasis involves the esophagus, it usually does so as an extensive and diffuse infection. In our experience, however, esophageal candidiasis in patients with the acquired immunodeficiency syndrome (AIDS) is clinically distinct from the same infection in patients with other immunodeficiency states. Of 25 patients with AIDS and esophageal candidiasis studied radiographically, 4 patients with localized involvement of the esophagus are presented. The clinical and radiologic manifestations of focal esophageal candidiasis in these patients are reviewed and compared to previously described cases of esophageal candidiasis.

Effects of radiation on the human gastrointestinal tract.

Radiation therapy directed at the abdomen may damage the digestive tract, the type and extent of injury depending on the dose of the radiation and the radiation sensitivity of the gut. Characteristic early changes are manifest in the mucosa of the gut: for later ulceration, changes in the collagen tissues and particularly in the vascular channels occur. This paper describes and characterizes injuries to the esophagus, stomach, small intestine and colon. It emphasizes the importance of recognizing radiation-induced damage to the gut which may occur early or late after radiation.

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.

Squamous cell carcinoma of the stomach.

Squamous cell carcinoma of the stomach is a rare, unusual lesion which tends to occur at a somewhat earlier age than adenocarcinoma. Grossly and radiologically the tumor is indistinguishable from adenocarcinoma and may involve any portion of the stomach. Although the pathogenesis of this lesion remains unclear, most authors favor the "metaplastic theory" for the development of the tumor. In this case it is felt that the tumor probably arose from gastric squamous mucosa present congenitally in the lesser curvature.

Ischemic disease of the small bowel and colon associated with oral contraceptives.

The widespread use of hormonal contraceptive pills by young women has caused a documented increase in thromboembolic disorders. This article describes yet another of the drug-induced complications namely, the development of ischemic bowel disease in seven cases. The ischemic changes which involved the small intestine in three and the colon in four patients became reversible after conservative management and discontinuance of oral contraceptive agents. The importance of clinical and radiologic consideration of ischemic bowel disease in young females receiving birth control pills is emphasized.

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.
