Cephalad Intracranial Migration of a Lumboperitoneal Shunt Catheter in a Patient with Idiopathic Intracranial Hypertension: A Case Report

Background

Lumboperitoneal (LP) shunting is an established treatment for medically refractory idiopathic intracranial hypertension (IIH), but is limited by comparatively high rates of mechanical failure. Cephalad (proximal, cranial) migration of the shunt catheter is a rare and likely underrecognized cause of shunt failure, with only a small number of cases reported.
