Histological diagnosis: Hydrocephalus internus post meningo ependimitidem. Haemorrhagia subarachnoidealis et oedema cerebri secundarium. Autopsy examination of 5,5-year-old patient was performed. Neuropathological evaluation in light microscopy was based on brain paraffin sections stained with Hematoxylin-eosin, Heidenhain and van Gieson method.The cortex and white matter were pushed to the periphery by the fluid-expanded ventricular system. Moving from the meninges towards the ventricular system, the following changes were found, which were more or less the same at all levels: the meninges were edematous, in some areas extremely thick, with a rich proliferation of collagen fibers. Remnant lymphocytic infiltrates were seen among the fibers and perivascularly. In addition, fresh subarachnoid extravasations were seen, locally taking the form of extensive hemorrhages. The frontal, right occipital cortex was formed normally, but with large cellular atrophy. The white matter was edematous, loosened in structure, with prominent astrocyte proliferation and significant stasis of capillaries and medium-sized vessels. The most characteristic lesions were found in the subependymal area of the temporal horn: several vessels with lymphocytic-plasmacytic infiltrates were found there, as well as two clusters of granulomatous infiltrate passing to the ventricular walls. Along the entire ventricular system, spongiotic necrosis with proliferation of mast cell and fibrous glia was seen. The picture was the evidence of an inflammatory process, most likely a simple purulent bacterial case, which had migrated from the basal meninges to the ependyma, leading to progressive closure of the ventricular system. Subsequently, the inflammatory case healed /the type of infiltration indicates this/, and the hydrocephalus, increasing with scarring, led to a descent with symptoms of edema and hemorrhage.
