Neonatal parechovirus leucoencephalitis- radiological pattern mimicking hypoxic-ischemic encephalopathy.

Aim: Our objective is to study the MR imaging pattern in neonatal parechoviral leucoencephalitis, a rare cause of neonatal white matter abnormality and to differentiate it from hypoxic-ischemic encephalopathy which is the commonest cause of white matter change in neonates.

Method: We evaluated 25 neonates who presented with features of encephalopathy. Cranial ultrasound and MR imaging was done in all the cases.
