Diffuse cavernous hemangioma of the rectosigmoid--CT scan, a new diagnostic modality, and surgical management using sphincter-saving procedures. Report of three cases.

Diffuse cavernous hemangioma of the rectosigmoid is a rare lesion. Preoperative recognition has been recorded but, because of lack of awareness and inconsistent diagnoses, inappropriate therapy still persists. Surgical therapy is the hallmark of treatment. Abdominoperineal resection has been advocated. Three cases of diffuse cavernous hemangiomas of the rectosigmoid, recognized preoperatively and treated successfully with sphincter-saving procedures, are reported. Use of the CT scan as a consistent diagnostic tool will be presented for the first time.
