A 62-year-old woman had sudden-onset headache and posterior neck pain, and a subarachnoid hemorrhage was revealed by unenhanced CT. Both multi-detector CT angiography and digital subtraction angiography were performed and revealed a small intracanalicular aneurysm of the left anterior inferior cerebellar artery. The patient underwent successful retrosigmoid craniectomy and trapping of the aneurysm. This case shows the ability of multi-detector CT angiography to indicate bony landmarks that can alter the surgical approach.
一名62岁女性突发头痛和后颈部疼痛,平扫CT显示蛛网膜下腔出血。多排CT血管造影和数字减影血管造影均已进行,显示左小脑前下动脉存在一个小的管内动脉瘤。该患者成功接受了乙状窦后开颅术及动脉瘤夹闭术。本病例显示了多排CT血管造影指示可改变手术入路的骨性标志的能力。
