摘要
目的回顾性分析中脑周围非动脉瘤性蛛网膜下腔出血的临床表现、影像特点及其预后。方法1994年1月-2004年1月间83例自发性蛛网膜下腔出血造影阴性,18例符合中脑周围非动脉瘤性蛛网膜下腔出血的诊断,复习其临床表现、影像学资料及相关文献,平均随访4.3年。结果中脑周围非动脉瘤性蛛网膜下腔出血的患者起病时多无意识障碍,病程呈良性过程,无再出血,出血局限在中脑周围池,以脚间池为多(50%),预后较好。结论中脑周围非动脉瘤性蛛网膜下腔出血是一种特殊类型的蛛网膜下腔出血,呈良性病程,预后较好,但须严格其诊断,以免误诊造成严重后果。
Objective To analyse the unique clinical and iconographic features of perimesencephalic nonaneurysmal subarachnoid hemorrhage （PNSH）. Methods We respectively reviewed the clinical and iconographic documents of 83 cases of angiogram-negative subarachnoid hemorrhage. 18 cases were diagnosed as PNSH. Result PNSHs were not companied with loss of consciousness at SAH onset. All patients were classified into Hunt and Hess Grade Ⅰ or Ⅱ . There were no rebleeding during follow-up. PNSHs have a more benign course. Conclusion PNSH is a unique type of SAH. It have excellent outcome. Its diagnosis must be strict.
