19 year-old female with history of hydrocephalus status post VP shunt placement presenting with headache and vomiting. Evaluate for worsening hydrocephalus. Ventricular shunt catheter enters the right parietal burr hole with catheter tip in the left lateral ventricle, unchanged in position. Stable morphology and increased volume of both lateral ventricles is evident. Previously evident contrast within the left lateral ventricle is no longer seen. There is no evidence of intracranial hemorrhage, abnormal extra-axial fluid collections, or edema. The remainder of the cerebral and cerebellar hemispheres are stable in appearance. The pituitary gland appears mildly prominent, which correlates with convex morphology seen on recent MRI.Postoperative changes status post right parietal burr hole and are unchanged, with the remainder of the calvarium visualized osseous structures intact. Visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Stable hydrocephalus with no additional acute findings to explain headache and vomiting.
