Bilateral subdural empyema diagnosed after middle meningeal artery embolization: illustrative case

Background: Middle meningeal artery (MMA) embolization has emerged as an effective adjunctive treatment for chronic subdural hematomas (SDHs) and is generally associated with a favorable safety profile. As utilization increases following recent randomized trials, uncommon complications are increasingly being recognized. The authors present a case of bilateral subdural empyema following bilateral MMA embolization.
