Case Report: Idiopathic myointimal hyperplasia of mesenteric veins mimicking inflammatory bowel disease: a case report with literature review.

ABSTRACT:

Background

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare and poorly understood disease, typically affecting the rectosigmoid colon of young, otherwise healthy men. Clinically, it is often mistaken for inflammatory bowel disease, as biopsies show ischemic mucosal changes without classic inflammatory features. Surgical resection is both diagnostic and curative, although the etiology of IMHMV remains unclear.

Case presentation

We report the case of a female patient with IMHMV involving the right hemicolon, concomitant with Clostridium difficile infection. Her symptoms persisted despite targeted treatment for C. difficile. She subsequently underwent a laparoscopic right hemicolectomy, which revealed mesenteric vein occlusion due to myo
