Epidural Blood Patch for Postdural Puncture Headache due to Lumboperitoneal Shunt Placement in a Patient With Pseudotumor Cerebri: A Case Report

The epidural blood patch (EBP) is commonly used to treat postdural puncture headaches (PDPHs) from spinal anesthesia, dural puncture with epidural anesthesia, and diagnostic and therapeutic lumbar puncture. We present a case of a patient with pseudotumor cerebri (idiopathic intracranial hypertension) who had a lumboperitoneal shunt placed for persistent headaches and subsequently developed symptoms similar to a PDPHs that were successfully treated with an EBP. While the exact mechanism by which our patient was experiencing PDPH symptoms is unknown, the EBP administration proved to be both therapeutic and diagnostic by ruling out shunt catheter malfunction through a resolution of symptoms.
