Male, 62 years old, status post third ventriculocisternostomy. History of ventriculomegaly and cortical stenosis. Sagittal fiesta best demonstrates a small anatomic defect consistent with the provided history of third ventriculocisternostomy. Sagittally acquired CSF flow analysis demonstrates a tuft of CSF flow through the region of this defect.Stable, marked ventriculomegaly is redemonstrated involving the lateral, third and fourth ventricles, not significantly changed from the prior examination. There are stable scattered foci of T2 hyperintensity within the cerebral white matter which are nonspecific. The cerebellar vermis is hypoplastic inferiorly, unchanged. Note is made of a presumed ventriculostomy catheter tract to the frontal lobe.
