Abstract
Computed tomography (CT) is playing an increasingly greater role as the initial diagnostic
imaging modality for acute abdomen. Abdominal pain is the most common presenting complaint
for intestinal lymphoma, and acute abdomen is a not infrequent admitting complaint.
We present the CT findings of five patients with intestinal lymphoma whose initial
complaint was acute abdomen. Of these five patients, four had an identifiable mass
that was located in the right lower quadrant, with the fifth patient having no identifiable
mass on CT. The average mass size was 7.8 cm. Three of the patients showed involvement
of the colon only, and two showed involvement of the small bowel only, with acute
abdomen in only one of the patients with small-bowel involvement being due to direct
extension from mesenteric lymph nodes. Pneumoperitoneum and free intraperitoneal fluid
were seen in two patients. It is important, therefore, that the radiologist be aware
that one of the causes of acute abdomen with primary bowel involvement is lymphoma,
which can simulate appendicitis or diverticulitis in its presentation clinically and
by physical examination.
