Antral mucosal diaphragms in infants and children.

The antral mucosal diaphragm in infants and children has been reported in the literature in 48 patients. We have encountered antral mucosal diaphragms in 6 children. Only 3 of these 6 patients required surgery.

Antral mucosal diaphragms in adults.

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.

Megalocytic interstitial nephritis: ultrasonic and radiographic changes.

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.

The multi-channelled pylorus.

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.

Jejunal monilial bezoar following total gastrectomy.

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.

Atypical esophageal diverticula associated with progressive systemic sclerosis.

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.

A film changer for small animals.

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.

Corrugated mucosal pattern in the esophagus associated with progressive systemic sclerosis.

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.

Gastric pseudo-ulcers: membrana angularis and pyloric torus defects.

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.
