History of hypertrophic pituitary, hydrocephalus, slit vent syndrome: yearly follow up. Brain: There is a right transoccipital ventricular catheter with unchanged mild T2 hyperintensity surrounding the catheter, which may represent gliosis and/or encephalomalacia. The ventricles are unchanged in size and configuration. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are unchanged. There is a subcentimeter right maxillary sinus retention cyst.Pituitary: There are postoperative findings related to transsphenoidal surgery. There is an unchanged punctate area of T2 hyperintensity along the left lobe of the pituitary gland. The pituitary stalk is intact. There is no mass effect upon the optic apparatus or cavernous sinuses.
1. Unchanged appearance of the shunted ventricular system.2. Unchanged appearance of the pituitary gland without evidence of recurrent hypertrophy.
