benign external hydrocephalus

A condition that occurs in infancy and early childhood, which is characterised by enlargement of the subarachnoid space, typically in the frontal areas and interhemispheric fissure with raised intracranial pressure without significantly enlarged ventricles. It is attributed to an absorption deficiency and typically resolves within a year.
