Forty-nine patients were found to have computed tomographic (CT) and clinical evidence for infarction in the brainstem and cerebellum. Seventeen had correlative angiography, of which 15 had a severe occlusive vascular lesion somewhere in the vertebrobasilar system. The correlation between angiographic and CT localization of the infarcts was not good. Inferiorly located infarcts were probably often missed on CT because of basal artifacts. Combined infarctions of the brainstem and cerebellum were common. Nineteen of the 49 patients had an associated mass effect in the posterior fossa; in eight of these, hydrocephalus developed. Although immediate surgical decompression of the posterior fossa has been recommended for treatment of this complication, most of these patients recovered well with careful medical decompression.
49例患者经计算机断层扫描（CT）检查及临床诊断发现存在脑干和小脑梗死。17例患者接受了相关血管造影检查，其中15例在椎基底动脉系统的某处存在严重的闭塞性血管病变。梗死灶的血管造影定位与CT定位之间的相关性不佳。由于底部伪影，CT检查可能经常漏诊位于下方的梗死灶。脑干和小脑合并梗死很常见。49例患者中有19例在后颅窝出现了相关的占位效应；其中8例出现了脑积水。尽管有人建议对这种并发症立即进行后颅窝手术减压，但大多数患者通过精心的药物减压恢复良好。
