Imaging of Cerebrospinal Fluid Shunts and Their Complications

The authors aim to address the imaging characteristics and complications associated with cerebrospinal fluid (CSF) shunts used to treat hydrocephalus, a condition affecting 1%-2% of the U.S. population. They highlight the prevalence of shunt failure and the importance of imaging in diagnosing and identifying the underlying causes of shunt malfunction, which can occur both early and late after placement. The review emphasizes the need for radiologists to be familiar with the various complications and their imaging manifestations to ensure effective management of patients with CSF shunts.
