Traumatic middle meningeal artery aneurysm causing intracerebral hematoma: a case report and review of literature

BACKGROUND: Traumatic aneurysms of middle meningeal artery (MMA) are rare. Traumatic MMA aneurysms usually present with extradural hematomas, whereas intradural intraparenchymal hematomas are exceedingly rare. CASE DISCUSSION: We report a 30-year-old man who presented 1 year after head injury with spontaneous right frontal intraparenchymal hematoma. Investigations revealed a MMA pseudoaneurysm, which was successfully treated surgically. CONCLUSION: Traumatic MMA pseudoaneurysm producing intracerebral hematoma (ICH) is rare and can be listed as a cause of spontaneous acute ICH.
