Progressive multicystic encephalopathy: is there more than hypoxia-ischemia?

Progressive multicystic encephalopathy following prenatal or perinatal hypoxia-ischemia is a well-described phenomenon in the literature. The authors report on a term infant with a devastating encephalopathy and severe neuronal dysfunction immediately after delivery without a known antecedent of prenatal or perinatal hypoxia or distress. Clinical and paraclinical findings in the patient are compared with those described in the literature.
