Progressive Multicystic Encephalopathy: Is There More Than Hypoxia-Ischemia?

Abstract

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. The authors focus on the specific results guiding to the final diagnosis of progressive multicystic encephalopathy and the timing of morphologic changes. As in this case, if the criteria of an acute hypoxic event sufficient to cause neonatal encephalopathy are not met, then factors other than hypoxia-ischemia may be leading to progressive multicystic encephalopathy.
