A 49-year-old man who had been suffering from disturbance of hearing for 5 years suddenly developed severe headache, nausea, and vomiting. Computed tomography (CT) scans both with and without contrast medium enhancement, performed on the day of admission, showed a nearly round high-density area in the left cerebellopontine angle. A left transaxillary vertebral angiogram showed no aneurysm or arteriovenous malformation. Hemorrhage from a tumor in the left cerebellopontine angle was suspected. CT scan without contrast medium enhancement, performed on the 17th day after onset, showed only a small, ill-defined high-density area in the cerebellopontine angle. An operation was performed on the 20th day after onset. The tumor was totally extirpated together with a clot. Histologically the tumor was an acoustic neurinoma with hemorrhage and necrosis. The postoperative course was favorable. Massive hemorrhage from primary intracranial tumors, especially acoustic neurinomas, is discussed. Radical operation on the tumor should be performed as soon as possible.
一名49岁男性，听力障碍5年，突然出现剧烈头痛、恶心和呕吐。入院当天进行的增强及未增强计算机断层扫描（CT）显示左小脑脑桥角有一个近乎圆形的高密度区。左经腋椎动脉血管造影未显示动脉瘤或动静脉畸形。怀疑是左小脑脑桥角肿瘤出血。发病后第17天进行的未增强CT扫描显示小脑脑桥角仅有一个小的、边界不清的高密度区。发病后第20天进行了手术。肿瘤连同血块被完全切除。组织学检查肿瘤为伴有出血和坏死的听神经瘤。术后病程顺利。讨论了原发性颅内肿瘤尤其是听神经瘤的大量出血情况。应尽快对肿瘤进行根治性手术。
