Authors analyzed CT findings of 8 patients with tuberculous lymphadenitis and one case of tuberculous abscess diagnosed surgically or clinically. The results were as follows; 1. Soft tissue density masses were noted in 8 patients in paraaortic, mesenteric, peripancreatic, celiac, porta hepatis, and esophagogastric junction areas in order of frequency, and these correspond to lymph node groups of the same name. On contrast enhanced CT, rim enhancement with multilocular low densities indicating caseous necrosis were noted in 3 patients, ill defined low densities were seen in 3 patients, and no definite changes were noted in 2 patients. 2. Two or more lymph node groups were involved in 6 patients, and one lymph node group was involved in two patients. 3. A huge cystic mass with relatively irregular rim enhancement and small anount of solid component occupied nearly entire upper abdomen in 1 patient and this was confirmed as tuberculous abscess in peritoneum. 4. In 2 cases, bowel all thickening was suggested in cecum, ascending colon, and terminal ileum.
