A case is reported of monilial bezoar involving the jejunum following total gastrectomy in a patient who was neither severely debilitated nor immunosuppressed. This condition should be differentiated from the more commonly occurring postgastrectomy phytobezoar.
The entity of multiple pyloric channels may be congenital but the majority are acquired lesions representing fistulae secondary to peptic ulcer disease in the pyloroduodenal region. The fistula usually joins the lesser curvature of the stomach with the superior aspect of the duodenal bulb. The multichannelled pylorus produces a characteristic radiological appearance on barium mean examination with a double or split barium column in the region of the pylorus. Four cases are described and illustrated.
The radiologic and ultrasonic findings are presented in a case of megalocytic interstitial nephritis, a very rare condition, in many ways similar to renal malacoplakia. The role of ultrasound in the interpretation of the radiographic changes is discussed. Excretory urography will demonstrate a nonspecific renal mass effect and angiography may rule out evidence of tumor. Ultrasonic correlation can be highly suggestive of an interstitial parenchymal lesion.
A group of 53 patients with the diagnosis of antral mucosal diaphragm is reported. In over 50% of the cases the diaphragm was considered an asymptomatic lesion. In addition, an autopsy study in 29 unselected cases is reported with demonstration of five antral mucosal diaphragms in different forms. On the basis of these findings, it is evident that the antral mucosal diaphragm in the adult is not an acquired lesion secondary to peptic ulcer disease, but may be congenital. In addition, techniques of radiologic evaluation of the diaphragm for significant narrowing of the central aperture using the compressed barium tablet, and for significant gastric outlet obstruction using the "barium burger" examination, are described.
Five cases of unusual esophageal diverticula associated with progressive systemic sclerosis (scleroderma) or collagen vascular disease are presented. These wide-mouthed saccular diverticula were infrequently seen in a group of PSS patients with the typical motility disturbance of esophageal involvement and are reminiscent of the diverticula of the colon involved by PSS.
Three cases of unusual corrugated mucosal pattern in the esophagus accompanying the typical motility disturbance of progressive systemic sclerosis (PSS) are reported. The changes were rarely seen in a group of patients with esophageal involvement by PSS.
A 70mm spot-film camera was modified for use in small-animal studies. The film is exposed directly by x rays and yields a high-quality image.

The membrana angularis and pyloric torus defects are two physiologic bulges which can simulate ulcerations along the lesser curvature of the stomach. The muscular anatomy of the stomach and the mechanism which produces these pseudo-ulcers are discussed. Both pseudoniches can be seen transiently in normal individuals but occasionally are such prominence as to become diagnostic pitfalls. The features and significance of each pseudo-ulcer are reviewed in an attempt to facilitate recognition on the upper gastrointestinal barium examination.
