[Isolated rectal tuberculoma diagnosed after endoscopic surgery: a case report].

Intestinal tuberculosis commonly affects the ileocecal area and the terminal ileum, and is extremely rare in the rectum, with isolated rectal involvement being even rarer. This paper described a case of an isolated rectal tuberculoma in a female patient of 44 years old, Yi ethnicity, who was admitted to the hospital with abdominal distension and constipation. She had a history of hepatitis B virus infection. A colonoscopy revealed a rectal mass, and an endoscopic resection was performed. Post-operative pathological examination confirmed rectal tuberculosis, with no evidence of extra-rectal tuberculosis infection found. The final diagnosis was an isolated rectal tuberculoma. In cases where endoscopic examination suggests a rectal tumor, especially in patients with immunosuppressive conditions such as HIV or diabetes, the possibility of tuberculoma should be considered.
