An example of traumatic false aneurysm of the right superior cerebellar artery is described. The chronicity of the clinical picture and a positive brain scan strongly suggested a posterior fossa neoplasm; however, the angiographic findings permitted a specific diagnosis to be made.

Plain films of the abdomen in advanced states of schistosomiasis reveal massive splenomegaly without evidence of splenic calcification. The liver may be enlarged in the early stages but ultimately decreases and becomes small. Ascites is evident in far advanced disease. Chest films are negative in the early stages, but in advanced disease, dilated pulmonary arteries, right ventricular enlargement, and dilatation of the azygous vein may be recognized. Granulomata are seen as multiple small rounded densities scattered throughout both lung fields. The routine barium swallow will reveal unsuspected esophageal varices. Nine patients were studied preoperatively by panhepatic angiography and 14 post-operatively following splenorenal shunt. Thrombosis of the shunt and hepatic encephalopathy were common postoperative complications.

The principles of construction of a continent ileostomy by means of a reservoir as originally described by Kock are reviewed. Roentgenologic studies in 5 patients with such reservoirs are described. There may be a correlation of incontinence with peristaltic activity as well as nipple valve extrusion. The radiologic features are explained in terms of the anatomy of the reservoirs. One patient with postoperative ileitis is described. Roentgenologic studies may be of particular value to the surgeon in follow-up of these patients by demonstration of postoperative nipple valve extrusion and inflammatory changes in the pouch or remaining small intestine.
