Fig 2 A, A sagittal computed tomography (CT) shows a traumatic external carotid artery (ECA) pseudoaneurysm (PA) in a 25-year-old man (patient 6). A mass with obvious enhancement is demonstrated inside the right mandibular ramus and extending to the infratemporal fossa. Right common carotid artery angiography in (B) anteroposterior and (C) lateral views shows the PA and an arteriovenous fistula (AVF) between the ECA and the jugular vein. Almost invisible demonstration of the branches of ECA distal to PA is present. D, A contrast-enhanced CT scan demonstrates complete obliteration of the PA and placement of coils 2 weeks after embolization. Right common carotid artery angiography in (E) anteroposterior and (F) lateral views demonstrates no remaining PA or AVF.

Fig 3 A, An axial contrast-enhanced computed tomography (CT) scan of a of 54-year-old man with enlarging left parapharyngeal pulsatile mass (patient 2) demonstrates a mass with obvious enhancement (arrow). Angiography of the left internal maxillary artery (IMA) in (B) anteroposterior and (C) lateral views shows the pseudoaneurysm (PA). D, An axial view contrast-enhanced CT image, obtained 4 months later, shows complete obliteration of the PA (arrow). Angiography of the (E) left common carotid artery and (F) IMA reveals occlusion and no remaining of PA after embolization of the distal and proximal edge of IMA.
