ANEURYSMAL LYMPHOMA OF THE SMALL INTESTINE

Abstract

Two unusual cases of aneurysmal lymphoma of the small intestine are reported, one showing early, the other late roentgen features. The clinical manifestations, the pathophysiology and especially the roentgen findings are discussed. In the early form of aneurysmal lymphoma, the involved segments show a ragged, geographic pattern of the bariumfilled lumen and a companion mass. In the advanced form, large, aneurysm-like dilatations are demonstrated on the small bowel study. Such aneurysmal cavities accumulate barium and retain it for days. In both instances, the small intestinal loops entering and leaving the aneurysmal lymphoma are normal in caliber and free of disease.
