Case Notes
History
74 yo female with VP shunt in place who presents with acute headache being evaluated for acute hemorrhage.Exam
MR susceptibility (SWI)
Prior Study
CT head: pre1. Significant residual ventriculomegaly, which is partially compensated by the VP shunt. No significant transependymal fluid migration remains.
MR T1-w pre contrast
1. Partially compensated chronic hydrocephalus following VP shunt placement. Etiology of the hydrocephalus is indeterminate.
T2-w spin echo
1. There is partially compensated low grade hydrocephalus with improved, but still enlarged ventricular system, following VP shunt placement. There is no appreciable transependymal fluid indicating a relatively low pressure intraventricular type of chronic hydrocephalus. Etiology of the hydrocephalus is indeterminate, but recurrent microhemorrhags into the CSF are suspected; no specific bleeding source is evident.
