a An axial contrast-enhanced computed tomography (CT) scan demonstrates a mass with obvious enhancement (arrow) in right sublingual space s/o pseudoaneurysm. b Coronal section at same level shows osteonecrosis of the adjacent mandible and multiple air foci (arrow) and pseudoaneurysm (open arrow). c CT MIP section shows origin of the pseudoaneurysm from right facial artery (arrowhead). Endovascular treatment of facial artery aneurysm. d Fluoroscopic image of common carotid artery(CCA) contrast run shows facial artery (arrow) through multipurpose catheter ((MPA catheter, Cook medical llc, USA). e Superselective run through microcatheter (2.7 Fr Progreat microcatheter, Terumo, Japan) in facial artery (open arrow) shows pseudoaneurysm sac (arrow). f Post coil embolization (hilal embolization microcoil™, Cook medical llc, USA) with scaffolding technique (large diameter coil was first placed forming a 3D scaffold, in that small diameter coil were placed to completely occlude the lumen) fluoroscopic angiogram image shows complete occlusion of feeding artery and preserved distal IMA (internal maxillary artery) and proximal ligular artery
