[Perimesencephalic subarachnoid hemorrhage nonaneurysmatic: report of a case and literature review].
A 42 year-old man with subarachnoid hemorrhage was admitted in our Service (Hunt & Hess grade II). CT-scan disclosed predominantly perimesencephalic subarachnoid hemorrhage. Digital subtraction angiographic study did not disclose either cerebral aneurysm or any other potential site of intracranial bleeding. The evolution was uneventful. A DSA was repeated one month later and was negative. Four months later, the patient was asymptomatic. The authors review the literature and emphasize the importance in recognizing this benign clinical form of nonaneurysmatic subarachnoid hemorrhage.
