Leptomeningeal hemorrhages (LMH) were studied neurohistologically and electron-microscopically on 54 stillborn and liveborn infants. Five main types of LMH were revealed: diapedesal in the grooves; punctate; macular; large focal, and hematomas. In 33.3% of cases there was a combination of different LMH types. Their morphological and pathogenetic features are described. LMH are further subdivided according to the number of foci as single and multiple, according to their extension as generalized and localized, according to their localization as unilateral or bilateral (symmetric and asymmetric) and according to the localization of extravasation as subarachnoid, subpial and mixed. The most significant lesions of the underlying dura matter are observed in cases of large focal LMH and hematomas.
对54例死产和活产婴儿的软脑膜出血进行了神经组织学和电子显微镜研究。发现软脑膜出血有五种主要类型：沟内漏出型；点状；斑状；大灶性和血肿型。33.3%的病例存在不同类型软脑膜出血的组合。描述了它们的形态学和发病机制特征。软脑膜出血还可根据病灶数量分为单发和多发，根据范围分为全身性和局限性，根据部位分为单侧或双侧（对称和不对称），根据外渗部位分为蛛网膜下腔、软膜下和混合型。在大灶性软脑膜出血和血肿病例中观察到最明显的硬脑膜病变。
