Answer

Benign external hydrocephalus (benign enlargement of the subarrachnoid spaces of infancy) is a self-limiting absorption deficiency of infancy and early childhood with mildly raised intracranial pressure (ICP) and enlarged subarachnoid spaces. The ventricles usually are not enlarged significantly, and resolution within 1 year is the rule. [5]
