Imaging is done to reveal the underlying cause and confirm the diagnosis. Shunt infection is one of the common causes of shunt malfunction. FDG PET CT is an accepted infection imaging tool and can be used to diagnose shunt infection accurately in a patient with high clinical suspicion. Copyright © 2020 Wolters Kluwer Health, Inc.
