Bilateral subdural hematoma after inadvertent dural puncture during epidural analgesia

Post-dural puncture headache (PDPH) is typically a benign complication of dural puncture that is clinically diagnosed. It commonly presents as a throbbing and positional headache that occurs 24-48 h after dural puncture. Subdural hematomas, if unrecognized, may occur as a rare and life-threatening complication of dural puncture.

We aim to describe the clinical features and sequelae of a rare complication that may result as a consequence of inadvertent dural puncture that, if unrecognized, has the potential to become a life-threatening complication from a common procedure.

We report the case of a previously healthy 17-year-old primigravida female who initially presented 4 days postpartum with clinical features and imaging studies consistent with PDPH. The patient's symptoms were unremitting, and within 4 weeks, she developed bilateral subdural hematoma. With prompt recognition and diagnosis, she was treated with conservative medical management and subsequently improved on follow-up.

Patients with unremitting PDPH should prompt the clinician to suspect the development of subdural hematoma as a potential life-threatening complication of an otherwise benign condition.
