An 18-year-old man who had severe recurrent rectal bleeding and hematuria was found to have a diffuse cavernous hemangioma of the rectosigmoid. A computed tomographic (CT) study was indicated to evaluate tumor extension and therapeutic possibilities. CT scanning revealed a large mass with phleboliths throughout the true pelvis and nodular indentations in the rectosigmoid wall involving the dome and posterior wall of the bladder. A nonhomogeneous and subtle enhancement of the lesion was noticed after injection of contrast medium.
一名18岁男性，有严重复发性直肠出血和血尿，被发现患有乙状结肠直肠弥漫性海绵状血管瘤。进行了计算机断层扫描（CT）检查以评估肿瘤的范围和治疗可能性。CT扫描显示在整个真骨盆内有一个伴有静脉石的大肿块，乙状结肠直肠壁有结节状压迹，累及膀胱顶部和后壁。注射造影剂后，发现病变有不均匀的轻微强化。
