The histopathological findings include as following: Gliosis (52%), Neuronal necrosis (37%), Perivascular cuffing (5.4%), hyperemia and hemorrhage in cerebral tissues (32.9%), hyperemia and hemorrhage in meninge(19.2%), prevascullar and preneuronal edema (52%), Meningial edema (16.4%), Vacuole in neurons (2.7%), Vacuoleinneuropil( 8.2% ),protozoal cyct(5.4%). Frequency of fetal brain lesions consists of: meningitis (9.6%), encephalitis (50.7%), (non suppurative encephalitis 38.3%, suppurative encephalitis 12.3%), meningoencephalitis (8.2%), Encephalomalacia (1.4%), congenital anomalies (6.8% )(hydrocephaly andhydranencephaly). Non purulent encephalitis was the most common lesion in fetal brains that could be caused by viral and protozoal agents. 71 % of non-supporative encephalitis consisted of multifocal necrotic encephalitis which are mostly caused by protozoa. The etiology of abortion should be considered in future studies.
