“…3 In the absence of a fracture or penetrating wound, like in our patient, some traumatic aneurysms have been observed on arteries in relation to the edge of rigid meningeal structures. 1 We believe that in our case, the head trauma produced a rotary movement of the brain within the skull, tearing an arterial branch of the SCA that passes through the perimesencephalic cistern.…”

“…Aneurysms arising from the SCA are rarer and only six cases had been reported. 1 Histologically, they are false aneurysms that contain none of the normal arterial layers but are lined by fibroconnective tissue surrounding a hole in the arterial wall. 2 Penetrating wounds were responsible for 40% of the traumatic aneurysms located in posterior circulation.…”

“…We evaluated 40 articles for full-text reading and excluded 28 studies after the full-text evaluation. We excluded ten articles in which they performed endovascular treatment for MMA pseudoaneurysms [10,[12][13][14][15][16][17][18][19][20], nine studies presenting EDHs by the rupture of MMA pseudoaneurysms [21][22][23][24][25][26][27][28][29], three presenting incidental MMA pseudoaneurysms [9,30,31], one article without operative treatment for MMA pseudoaneurysms [32], four articles describing pseudoaneurysms in the MMA associated with arteriovenous fistula in the dura mater [33][34][35][36], and one article describing non-traumatic aneurysm in the MMA [37].…”

Intracerebral Hemorrhage Caused by the Rupture of a Traumatic Pseudoaneurysm in the Middle Meningeal Artery

Hematomas caused by the rupture of a pseudoaneurysm in the middle meningeal artery (MMA) after trauma usually present as epidural hematomas. Intracerebral hemorrhage (ICH) is extremely rare. We reviewed ICH due to the rupture of MMA pseudoaneurysms. We found that in cases of acute ICH, a pseudoaneurysm was attached to the outer surface of the dura mater and associated with dura tear. In patients with acute ICH, the intraoperative rupture of a pseudoaneurysm developed just after bone flap removal. In cases of delayed ICH, pseudoaneurysms adhered to the inner surface of the dura mater. In patients with delayed ICH, the intraoperative rupture of a pseudoaneurysm developed during dura opening and hematoma removal. In situations of dura tear after trauma, the rupture of pseudoaneurysms might lead to ICH via a dura tear. Pseudoaneurysms that develop in the MMA after trauma may exert pressure and result in the thinning of the dura mater. In this case, pseudoaneurysms will adhere to the inner surface of the dura mater after several days or weeks. ICH might develop through both acute and delayed mechanisms following the development of pseudoaneurysms in the MMA. Clinicians should pay attention to the timing of such ruptures during operations for both acute and delayed ICH.

Traumatic aneurysms comprise less than 1% of all intracranial aneurysms. Most of these aneurysms are actually false aneurysms, or pseudoaneurysms, which are caused by the rupture of entire vessel wall layers, with the wall of the aneurysm being formed by the surrounding cerebral structures. Traumatic pseudoaneurysms of the middle meningeal artery are also rare. Only four cases have been reported in the literature with intracerebral hematoma. In this paper, the authors report a case of a patient with a ruptured traumatic pseudoaneurysm of the MMA who presented with an intracerebral hematoma in the left temporal region immediately after trauma; the patient underwent endovascular treatment.
