• Pseudoaneurysms of the extracranial arterial tree are uncommon. To our knowledge, four cases of pseudoaneurysm of the internal maxillary artery have been reported, but there have been no reports of pseudoaneurysm of the extracranial segment of the middle meningeal artery. A 15-year-old girl, who suffered a gunshot wound in the right maxillary region, suffered a pseudoaneurysm of the proximal portion of the middle meningeal artery, as shown by carotid angiography six days after injury. The lesion was successfully treated with absorbable gelatin sponge embolization. Treatment of pseudoaneurysms reduces the risk of hemorrhage from subsequent rupture. Although these lesions are amenable to surgery, transvascular embolization or mechanical interruption appears to be simpler and equally effective.
