Large-bowel hemangiomas

A case of large-bowel hemangioma is presented, and radiologic and histologic abnormalities are illustrated. Ultrasonographic features, not previously described, are reported. The literature is reviewed and the frequency of misdiagnosis is emphasized. Pathologic classification, epidemiologic factors, and etiology are considered. Clinical manifestations and current approaches to recognition and management are summarized. Vascular tumors are serious, albeit uncommon, intestinal lesions. Greater awareness of the condition and earlier consideration of the diagnosis are prerequisites to lessened morbidity and improved survival.
