Abstract

The term 'periventricular leukomalacia' (PVL) usually covers necrotic and/or gliotic lesions from perinatal origin occurring in the periventricular ring of telencephalic white matter. Carrying motor and neuropsychological consequences, PVLs could be the most severe danger for very premature brains. Positive rolandic sharp waves recorded on EEG and precocious abnormally echogenous periventricular images on ultrasound suggest prospective periventricular cysts. Cystic periventricular cavitations certify the diagnosis of PVL. More subtle lesions of PVL do not reach the cystic grade and their diagnosis is confirmed by MRI. Treatment of infections is already available and potentially a tool for prevention. When the overwhelming glutamatergic signal has been triggered, neuroprotective agents turning off the excitotoxic cascade, including calcium blockers, growth factors and others, are promising therapeutic tools.
