Giant Cavernous Hemangioma in the Mesentery of the Descending Colon: A Case Report

ABSTRACT Gastrointestinal hemangiomas are rare, and those involving the mesentery are even more infrequent. The majority of cases reported in the literature had mesenteric cavernous hemangioma of the small intestine. To the best of our knowledge, this is the first documented case of a hemangioma originating from the mesentery of the descending colon. Preoperative diagnosis is exceedingly difficult, and various imaging modalities may be inconclusive. The patient was a 71‐year‐old Asian male presenting with recurrent dizziness and fatigue over several months. Physical examination revealed a mass that was palpable in the left mid‐abdominal region. Laboratory examinations suggested gastrointestinal bleeding and anemia. Abdominal CT scans revealed a large mesenteric mass in the descending colon. The mass was surgically resected, and histopathological examination confirmed mesenteric cavernous hemangioma. The patient showed no signs of recurrence in 1 year of postoperative follow‐up.
