Perimesencephalic subarachnoidal haemorrhage (PMH) is characterized by a typical blood distribution pattern in the basal cysterns in the CAT, missing evidence of an aneurysm in the panangiogram, a mild clinical course and a very positive prognosis. Between 1990 and 1995, 108 inpatients with non-traumatic subarachnoidal haemorrhage were treated in our clinic. Within this group 14 patients (13%) were identified retrospectively with a perimesencephalic haemorrhage distribution pattern in the CAT and a negative panangiogram. These patients experienced a mild clinical course with excellent outcome without rebleeding during the observation period of 2 to 50 months. All patients were fully able to work, and only two patients complained of frequent headaches. The mild clinical course, the negative panangiogram as well as the extremely positive outcome confirm the hypothesis of of a benign subgroup of non-traumatic subarachnoidal haemorrhages.
中脑周围蛛网膜下腔出血（PMH）的特征在于计算机断层扫描（CAT）中基底池典型的血液分布模式，全脑血管造影中未发现动脉瘤迹象，临床过程轻微且预后非常良好。1990年至1995年间，我院收治了108例非创伤性蛛网膜下腔出血的住院患者。在该组患者中，回顾性确定有14例（13%）在CAT中呈现中脑周围出血分布模式且全脑血管造影呈阴性。这些患者临床过程轻微，预后极佳，在2至50个月的观察期内未再出血。所有患者均能完全恢复工作，只有两名患者抱怨经常头痛。轻微的临床过程、阴性的全脑血管造影以及极其良好的预后证实了非创伤性蛛网膜下腔出血存在良性亚组这一假设。
