小脑出血约占脑出血的10％[1]。有人总结国内6篇报告共20例，仅发现1例为生前诊断，说明临床上误诊率甚高[2]，尤以猝死为主要表现者。为进一步探讨小脑出血病因和猝死机理，现将我们所见7例分析报告如下。材料和方法收集本教研室1955～1989年全部尸检材料，发现因小脑出血猝死 Cerebral hemorrhage accounts for about 10% of cerebral hemorrhage [1]. It was concluded that the domestic 6 reports a total of 20 cases, only found in 1 case of prenatal diagnosis, indicating that the clinical misdiagnosis rate is very high [2], especially sudden death as the main performance.
