Rupture of traumatic pseudoaneurysms of the middle meningeal artery (MMA) usually causes extradural hematoma. In rare cases, it may be a possible cause of intraparenchymal hematoma. We present 2 cases of intraparenchymal hematoma caused by rupture of traumatic pseudoaneurysms of MMA. Both patients had definite medical history of head trauma. Imaging examinations indicated temporal hematoma or frontal hematoma caused by rupture of pseudoaneurysm of MMA. After surgical management, both the patients had a favorable prognosis. The formation of the traumatic pseudoaneurysms, imaging findings, and the management were discussed, and we conclude that in the management of traumatic intraparenchymal hematoma, possibility of traumatic pseudoaneurysms must be considered. Surgery may be the prior choice for the treatment of traumatic pseudoaneurysms.
