Hydrocephalus with developmental delay and enlarging head. Status post remote endoscopic third ventriculostomy for aqueductal stenosis. There are postoperative findings related to endoscopic third ventriculostomy. There is no evidence of robust biphasic CSF flow across the third ventriculostomy. There is no significant interval change in the marked dilatation of the lateral and third ventricles with mild mass effect upon the brainstem and cerebellum. There is no significant interval change in the size of the cortical mantle. There is no evidence of acute infarction, hemorrhage, or mass. There is no midline shift. The major cerebral flow voids are grossly intact. The skull and scalp soft tissues are unchanged. There is persistent fluid within the bilateral middle ears and mastoid air cells.
1. No significant interval change in the hydrocephalus associated with aqueductal stenosis.2. No evidence of robust biphasic CSF flow across the third ventriculostomy.
