case_images: Follow-up brain CT showed mixed subdural hemorrhage and increased fluid collection at the site of the preexisting subdural hemorrhage [Figure 4].

case_images: After confirming bleeding cessation, duroplasty was performed using an artificial dura (Surgisis Biodesign Dural Graft, COOK Medical 7 cm x 10 cm), and the operation was complete [Figure 5].
case_images: Angiography showing thickened left middle meningeal artery. (a) Angiography of the left middle meningeal artery. (b) Embolization of the left middle meningeal artery was performed completely

case_images: Hemorrhagic spread to additional subdural areas was not noted, although the left middle meningeal artery was unusually thickened [Figure 6a]; complete embolization with histoacryl and lipiodol was successfully performed [Figure 6b].
case_images: Follow-up brain computed tomography image of the patient showing left epidural hematoma compressing the brain

case_images: Brain compression by the hemorrhage was also noted [Figure 7].
case_images: Brain computed tomography image before patient discharge. No hemorrhage and midline shift were noticed

case_images: After the operation, the patient returned to an alert state, maintained ambulation, and was discharged after a follow-up brain CT scan confirming resolution of the hemorrhage [Figure 8].
