Left-Sided Colonic Tuberculosis Presenting as Colonic Stricture: A Rare Presentation of a Common Disease.

Gastrointestinal tuberculosis (TB) mainly presents as an ileocecal disease, and colonic TB is more often seen with terminal ileal involvement. Isolated involvement of the descending colon by TB is uncommon and usually presents with chronic colitis. An acute presentation as intestinal obstruction because of tubercular stricture of the descending colon has not been reported. We encountered a young woman who presented with features of acute bowel obstruction. On evaluation, she was diagnosed with a case of descending colon stricture with a provisional diagnosis of malignant colonic stricture. Left hemicolectomy was performed, and histopathology revealed it to be tubercular stricture. Antitubercular therapy was given for 9 months, and she is doing well at follow-up. A differential diagnosis of TB at an unusual location should always be considered even when presented with atypical symptoms, especially for patients from the endemic zone of TB.
