抄録

<p>We report a case of coil embolization for a patient who showed progressive growth of a traumatic middle meningeal artery aneurysm (TMMA) and dural arteriovenous fistula (dAVF).</p><p>A 56–year–old woman was transported to our hospital with, suspected high–energy trauma. Acute epidural hematoma and multiple bone fractures were seen on head CT, but CT angio­graphy (3DCTA) showed no obvious traumatic vascular injury. On the day after the injury, no obvious neurological deteriora­tion was observed. MRI was performed on the 7th day for head­ache and cerebral contusion, and a right pseudoaneurysm of the middle meningeal artery was found suspected to be TMMA. Cerebral angiography performed on the 10th disease day revealed a right dAVF in addition to the right TMMA. Coil embolization was performed on the lesion, after which the headache disappeared and the lesions disappeared on 3DCTA.</p><p>In cases where a skull fracture is observed due to high–energy trauma, TMMA should be considered, with screening for traumat­ic vascular lesions using noninvasive MRA or 3DCTA. In addition, traumatic vascular injury may progress and needs to be evaluated over time.</p>
