Abstract

An 18-year old boy presented with a tumour involving a large part of the petrous bone. A radical resection of a petrous bone 'aneurysmal bone cyst' was achieved. A large defect in the dura adjoining the posterior surface of the petrous bone was made during surgery. Post-operative MR imaging showed complete tumour resection but herniation of cerebellum into the operative defect, a phenomenon probably assisting to seal the site of cerebrospinal fluid fistula.

摘要

一名18岁男孩出现了一个累及岩骨大部分的肿瘤。成功地对岩骨“动脉瘤样骨囊肿”进行了根治性切除。手术过程中在靠近岩骨后表面的硬脑膜上造成了一个大的缺损。术后磁共振成像显示肿瘤完全切除，但小脑疝入手术缺损处，这一现象可能有助于封闭脑脊液瘘的部位。
