A primary histiocytic lymphoma arising in the esophagus and its resultant spontaneous perforation is reported in a 69-year-old female. To our knowledge esophageal perforation occurring as a complication of a primary non-Hodgkin's lymphoma of the esophagus has not been previously reported.

Diffuse hepatocellular processes are not well imaged by most radiologic modalities. At present, CT has not added significantly to the evaluation of hepatocellular disease, particularly in the cirrhotic liver. The CT patterns of cirrhosis previously described are reviewed, and the pathophysiology of cirrhosis is discussed. In 3 cases, a pattern was seen in cirrhotic livers characterized by nonuniform attenuation with varied response to administration of intravenous contrast agents. With further evaluation of fatty infiltration and cirrhosis, CT may prove helpful in understanding these disease processes.
Computed tomography of the abdomen can aid the clinician in distinguishing intrahepatic from extrahepatic causes of jaundice. Hepatobiliary and pancreatic disease may be clearly defined. The timing and selection of further diagnostic and surgical procedures can be guided by computed tomography and unnecessary operations and prolonged hospitalization can be reduced. Computed tomography of the abdomen should not be used as a screening procedure but should be used after simpler techniques fail to establish a definitive diagnosis.
Nonsurgical diagnosis of colonic diverticulosis and most complications of diverticular disease is best established by barium enema study. Multiple diverticula can produce narrowing and shortening of the colon that is unrelated to any complication occurring in the diverticula. The diagnosis of diverticulitis is made radiologically be demonstrating the effects on the lumen of the bowel of the pathologic changes visible on gross inspection, eg, local abscess, intramural dissection, fistula, obstruction. Frequently the radiologic findings are subtle.
