The perimesencephalic type of nonaneurysmal subarachnoid hemorrhage (SAH) is a recently described clinical and radiological entity, with a good outcome. We carried out a retrospective analysis of 294 patients with subarachnoid hemorrhage, of whom 62 had a negative four-vessel angiography. We identified 20 cases with the typical computed tomographic (CT) pattern of perimesencephalic hemorrhage, in whom the prognosis was invariably good. However, five cases of aneurysmal subarachnoid hemorrhage had a more or less similar CT appearance: the diagnosis cannot be made on the CT image only and angiography remains mandatory. The use of bed rest, antifibrinolytics, and calcium antagonists is discussed.
中脑周围型非动脉瘤性蛛网膜下腔出血（SAH）是一种最近才被描述的临床和影像学实体，预后良好。我们对294例蛛网膜下腔出血患者进行了回顾性分析，其中62例四血管血管造影结果为阴性。我们识别出20例具有典型中脑出血计算机断层扫描（CT）模式的病例，其预后均良好。然而，5例动脉瘤性蛛网膜下腔出血病例的CT表现或多或少与之相似：仅通过CT图像无法做出诊断，血管造影仍然是必需的。本文还讨论了卧床休息、抗纤溶药物和钙拮抗剂的使用。
