Q: What is Phlebosclerotic colitis?


Answer: Phlebosclerotic colitis is a  form of ischemic colitis that results from venous obstruction, usually involving right side of the colon. It is hallmarked by fibrotic sclerosis and calcification of the walls of the mesenteric veins. It can be diagnosed or at least suspected on plain films (KUB), if linear calcifications are seen in the region of the right colon. Diagnosis can be confirmed by CT scan, with colonic wall thickening and mesenteric venous calcifications. This is usually self-limiting and resolve spontaneously, only requiring supportive treatment.
