A patient with hydranencephaly and PEHO-like dysmorphic features.

Progressive encephalopathy with Edema, Hypsarrhythmia, and Optic atrophy (PEHO syndrome) is a rare recessive autosomal neurodegenerative condition essentially described in Finland. The term PEHO-like syndrome has been proposed for patients who share clinical features of PEHO syndrome but lack the cerebellar atrophy, one of its major diagnostic criteria. We describe a patient presenting with hypoxic-ischaemic encephalopathy and PEHO-like syndrome features.
