The term can be misleading, because there is no softening of the tissue in PVL. The white matter is the inner part of the brain. The early signs of PVL include periventricular white matter necrosis followed by the subacute stage with possible intraparenchymal cyst formation and the late stages of parenchymal loss and enlargement of the ventricles. Anyone might get PVL. [6][8] Many patients exhibit spastic diplegia,[2] a condition characterized by increased muscle tone and spasticity in the lower body. 1993 Aug;92(8):697-701.

Published online 1974. doi:74:591-600. [2][6] One of the reasons for this discrepancy is the large variability in severity of cerebral palsy. In severe cases, post-mortem examinations revealed that 75% of premature babies who died shortly after birth had periventricular leukomalacia. [1] Cysts occur when large and confluent focuses of PVL, with mixed necrosis (kollikvacia in the center and coagulation rim at the periphery). Consequent cell death and thinning of white matter around the ventricles leaves fluid-filled spaces called lateral ventricles9.
