Cerebral Venous Sinus Thrombosis After Lumbar Epidural Steroid Injection: A Case Report

Cerebral venous sinus thrombosis (CVST) is an exceedingly rare complication of epidural anesthesia, with only a handful of known cases after epidural steroid injection (ESI). We report a case of CVST in a 33-year-old male patient that presented with headache after lumbar ESI. His clinical status initially improved on anticoagulation in the intensive care unit. However, he had a sudden worsening of cerebral edema that required an emergent hemicraniectomy. Ultimately, the patient was pronounced dead by neurologic criteria. This case highlights the importance of keeping this rare but potentially fatal diagnosis in the differential even in lower-risk patient populations.
