Abstract

Chronic subdural hematomas (CSDHs) are a common neurosurgical disease for which middle meningeal artery (MMA) embolization is emerging as an attractive and efficacious endovascular treatment modality. We present the first known case of a Streptococcus intermedius epidural abscess that resulted following MMA embolization for a left-sided CSDH that required evacuation and washout through a craniotomy. Intracranial infections can be a potentially devastating complication from MMA embolization in this patient population.
