Status post third V-C placement and Rickham reservoir. Rule out ICH. A right frontal ventricular shunt has its tip at the midline. Pneumocephalus and subcutaneous emphysema are likely postprocedural. There is no evidence of intracranial hemorrhage. The lateral and third ventricles are enlarged, and the frontal horns appear more rounded than on the prior MRI. After accounting for differences in technique, this is suggestive of slight interval increase in size of the lateral and third ventricles. The fourth ventricle is within normal limits.The visualized paranasal sinuses and mastoid air cells are within normal limits for the patient's age.
Expected postoperative findings from recent shunt placement. No evidence of intracranial hemorrhage. Slight interval increase in size of lateral and third ventricles.
