Persistent Post-dural Puncture Headaches One Year After Lumbar Puncture: A Case Report.

Post-dural puncture headaches usually occur when the cerebrospinal fluid (CSF) leaks due to trauma to the dura mater. This often results in spontaneous intracranial hypotension characterized by orthostatic headaches, neck stiffness, and nausea. In this case report, we discuss a 20-year-old male patient who developed symptoms of intracranial hypotension one year following a lumbar puncture. A spinal magnetic resonance imaging (MRI) revealed a CSF collection in the epidural space. This was treated successfully by an epidural blood patch (EBP) which resolved the patient's symptoms. This case highlights the necessity of recognizing delayed lumbar puncture complications and the need for a thorough history and physical exam in patients with such symptoms.
