title: Damage of maturing brain in the course of toxoplasmic encephalitis.
abstract: The aim of the study is to present the damaging influence of toxoplasmic encephalitis on newborn brains. The material consisted of six cases of toxoplasmosis who died during the first months of life. The neuropathological picture indicated indirectly the mechanism of spread of the inflammatory-necrotic process. In the first stage of pathologic process intensive inflammatory infiltrations in the periventricular white matter were seen. In the next stage the necrotic changes involved the majority of the hemispheric white matter. Further development of the disease transformed the brain hemispheres into thin-walled sacs composed of meninges and remnants of the nervous system. Finally, the inflammatory process resulted in hydranencephaly. Proliferation of subependymal glia evident in all cases and blocking the pathways of the cerebro-spinal fluid circulation, may have played a role in this process.
