AbstractPermanent cerebrospinal fluid diversion has a lengthy list of complications. We present an unusual clinical image of shunt catheter migration. A 54-year-old female had a history of subarachnoid hemorrhage that resulted in communicating hydrocephalus, which needed a ventriculoperitoneal shunt placement. On outpatient follow-up, she was found to have a sunken skin flap that was resistant to raising the shunt valve setting. A radiograph of the shunt system revealed that the peritoneal catheter had migrated into the thoracic cavity. On review of the patient's previous imaging, an area indicative of a minor pleural breach was identified that exposed the catheter to the negative thoracic pressure, which resulted in progressive catheter migration. The patient then underwent removal of the shunt system since her hydrocephalus had resolved. A pleural breach during shunt placement can result in the migration of the shunt catheter into the thoracic cavity under the effect of negative thoracic pressure.Copyright © 2020 Elsevier Inc.
