BACKGROUND Symptomatic cerebral vasospasm following posterior fossa extraaxial tumor resection is a rare phenomenon, with only 13 cases previously reported in the literature. The condition appears similar to supratentorial resection, intraaxial and aneurysmal subarachnoid hemorrhage (aSAH). majority of patients were not evaluated for prior symptom onset, leading delay diagnosis. OBSERVATIONS authors present their experience 56-year-old female who developed delayed after excision solid-cystic vestibular schwannoma. Routine postoperative brain computed tomography showed evidence basal cisterns. She was discharged on 9th day. On 11th day excision, she left hemiparesis, dysarthria, dysphagia readmitted. Angiography confirmed bilateral diffuse vasospasm. patient responded standard hyperdynamic therapy used secondary aSAH. LESSONS distant but challenging complication very high morbidity rate cases. A index suspicion required early diagnosis prompt management favorable outcome.
