Intracranial vasospasm following surgical removal of intracranial tumours is rare. To our knowledge there have been no previously reported cases of delayed vasospasm occurring post debulking of epidermoid cysts. We report a case in which vasospasm led to established cerebral infarction 2 weeks postoperatively. MRI and serial magnetic resonance angiography (MRA) reliably show initial multiple stenoses in the vertebral and internal carotid arteries followed by their spontaneous normalisation. MRA imaging is now of sufficient quality to enable it to be a safe and effective means of both looking for vasospasm and monitoring its resolution.
颅内肿瘤切除术后发生颅内血管痉挛较为罕见。据我们所知，此前尚无关于表皮样囊肿部分切除术后迟发性血管痉挛的报道。我们报告了一例术后 2 周发生血管痉挛导致脑梗死的病例。MRI 和连续磁共振血管造影（MRA）可靠地显示了最初的椎动脉和颈内动脉多处狭窄，随后自发恢复正常。MRA 成像的质量已经足够高，使其成为一种安全有效的寻找血管痉挛并监测其解决的方法。
