Imaging evaluation of CSF shunts.

OBJECTIVE
The objective of this article is to describe an approach to imaging CSF shunts. Topics reviewed include the components and imaging appearances of the most common types of shunts and the utility of different imaging modalities for the evaluation of shunt failure. Complications discussed include mechanical failure, infection, ventricular loculation, overdrainage, and unique complications related to each shunt type.


CONCLUSION
This article reviews the imaging features of common CSF shunts and related complications with which radiologists should be familiar.
