Definition
=========================================================================

● Various placental lesions are associated with neurologic impairment; the risk of impairment is increased with the number of lesions present (Arch Pathol Lab Med 2000;124:1785)
● Cerebral thrombi and infarcts may be present (Hum Pathol 1997;28:246)
● Presence of thrombi may indicate a coagulopathy in parents

Micro description
=========================================================================

● Placental lesions independently associated with neurologic impairment include severe fetal chorioamnionitis, diffuse chorioamnionic hemosiderosis and extensive avascular villi
● Also chorionic vessel thrombi, increased nucleated red blood cells, retroplacental hematoma, meconium-associated vascular necrosis, diffuse chronic villitis, perivillous fibrin, non-occulsive thrombi of chorionic plate vessels and severe villous edema (Arch Pathol Lab Med 1998;122:1091)
