title: A case of schizencephaly with subdural fluid collection in a neonate.
abstract: METHODS
  A neonate who had schizencephaly associated with ipsilateral chronic subdural fluid collection in the neonatal period is described. A boy was born to a healthy Japanese woman. After birth, the boy presented with rapid expansion of head circumference. Computed tomography (CT) and magnetic resonance images (MRI) of the head demonstrated left schizencephaly combined with a midline shift attributable to hydrocephalus. Thereafter, the patient gradually presented other symptoms caused by increased intracranial pressure. Ultrasonography and MRI of the head showed the presence of a subdural fluid collection overlaid on the schizencephaly. We identified the outer membrane by burr-hole craniotomy.
  
  
  CONCLUSIONS
  This was a rare case of schizencephaly associated with hydrocephalus and the formation of ipsilateral chronic subdural fluid collection.
