Status post endoscopic third ventriculocisternostomy for hydrocephalus due to aqueduct stenosis. Scoliosis and lipomyelomeningocele status post L4 and L5 osteoplastic laminoplasty, repair, and subtotal resection of intradural lipoma causing spinal cord tethering. Brain: There are postoperative findings related to endoscopic third ventriculostomy. There is no discernible 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 evidence of acute infarction, hemorrhage, or tumors. 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.Spine: There is unchanged cervicothoracic scoliosis and postoperative findings related to lipomeningocele surgery in the lumbar spine. There is persistent fluid signal within the central spinal cord diffusely, which measures up to 2 mm in width. The conus medullaris terminates at the L3-4 level. There is an unchanged fatty signal intensity of the filum terminalis and fat within the spinal canal extending from L5 to S3. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is a distended urinary bladder.
1. No significant interval change in the hydrocephalus associated with the aqueductal stenosis.2. No discernible CSF flow across the third ventriculostomy.3. Unchanged cervicothoracic scoliosis.4. The conus medullaris terminates at the L4 level and there is an unchanged fibrofatty filum terminalis and fat within the spinal canal that extends from L5 to S3. 5. Unchanged long-segment syrinx.
