中脑周围蛛网膜下腔出血（SAH）是一种相对良性的SAH。这种情况的病因尚不清楚，但静脉渗漏被认为是最可能的原因。本报告描述了一例中脑周围SAH患者，在弥散加权磁共振成像上表现为并发急性脑桥梗死。这些结果表明，在某些情况下，中脑周围SAH是由穿通动脉破裂引起的。
Perimesencephalic subarachnoid hemorrhage (SAH) is a relatively benign form of SAH. The etiology of this condition is unknown but venous leakage has been believed to be the most likely cause. This report describes a patient with perimesencephalic SAH who presented with a concurrent acute pontine infarct demonstrated on diffusion-weighted magnetic resonance imaging. These findings suggest that in some instances perimesencephalic SAH is caused by rupture of a perforating artery.
