Catheter breakage is a rare complication of continuous peripheral nerve blocks. Retained fragments pose a significant technical challenge, particularly when they migrate from the insertion site. We report a 39‐year‐old woman with Fabry disease and chronic foot pain refractory to pharmacologic therapy who, after a successful diagnostic posterior tibial nerve block, received a continuous peripheral nerve catheter. She initially experienced excellent analgesia but, by Day 4, developed severe neuropathic symptoms; imaging showed proximal migration of a catheter fragment. Computed tomography and fluoroscopy guided surgical retrieval of the fragment was performed. This case highlights the need for early recognition of catheter‐related complications, precise localization with advanced imaging, and timely surgical intervention to reduce adverse outcomes from retained catheter fragments.
