A 66-year-old man presented with clival chordoma associated with subarachnoid hemorrhage. Computed tomography showed subarachnoid hemorrhage in the right ambient cistern and a well-enhanced tumor in the petroclival region. Surgical exploration performed on the day of admission showed a clot in the tumor. The tumor was totally removed. Histological examination showed hemorrhage between the tumor and the dura. The diagnosis was clival chordoma. Subarachnoid hemorrhage in chordoma seems to occur by spreading of intratumoral hemorrhage into the subarachnoid space due to dural invasion.
一名66岁男性因斜坡脊索瘤合并蛛网膜下腔出血就诊。计算机断层扫描显示右侧环池蛛网膜下腔出血，岩斜区有一强化明显的肿瘤。入院当天进行的手术探查发现肿瘤内有血凝块。肿瘤被完全切除。组织学检查显示肿瘤与硬脑膜之间有出血。诊断为斜坡脊索瘤。脊索瘤中的蛛网膜下腔出血似乎是由于肿瘤内出血通过硬脑膜侵犯扩散至蛛网膜下腔所致。
