MRI is able to detect pathologic bowel segments in CD, as it allows the measurement of significant variations in wall thickness and contrast enhancement on changing from the active phase of the disease to remission.

We describe the case of a woman with rectorrhagia and rectal tenesmus. Colonoscopy revealed a 3-4 cm-long ulcerated lesion with a reduced colon lumen 35 cm from the anus, and multiple biopsies were obtained from the ulcerated region, but histopathology was non-specific. Biopsy culture was positive for M. tuberculosis. Anti-tuberculous chemotherapy was initiated on the diagnosis of segmental tuberculosis of the colon. Subsequent evolution was favorable, both clinically and endoscopically. Emphasis is placed on the importance of colonoscopy and biopsy in the diagnosis of tuberculosis of the colon.

Stenosis was of the diffuse type, associated with gastric ulcer and chronic atrophic gastritis. The patient was admitted to our Service with upper digestive tract hemorrhage after deterioration of the ulcer.
