Segmental tuberculosis of the distal colon: radiographic features in 7 cases.

The radiographic features of 7 cases of segmental colonic tuberculosis are described and illustrated. The lesions are generally short (5--7 cm) and may involve any part of the colon. They present radiographically as segmental granulomatous colitis or as annular, ulcerated lesions mimicking colonic carcinoma. Cases with sinus tract formation, severe narrowing, marked distortion, and fixation may occur. The association with pulmonary tuberculosis is common but not universal. The clinical findings are nonspecific, but the age group affected is mainly that of young adults. A short review of the pertinent literature is presented.
