Angio-CT showing the hypodense bulk at the right common carotid artery and at the bifurcation, dislocating the right internal jugular vein and invading the nearby parapharyngeal space (upper part) and the small hematoma enveloping the left iliac-femoral passage (lower part).. CT: computed tomography.

He underwent a duplex ultrasound of the neck and the left groin and an angio-computed tomography (CT) scan, both showing the presence of a right hypodense bulk at the common carotid artery and at the bifurcation, 40 x 37 mm in diameter, which extended for 58 mm in length and involved the ICA, dislocating the right internal jugular vein and invading the nearby parapharyngeal space (Figure 1). At the same time, a small hematoma enveloping the left iliac-femoral passage was present (Figure 1).

The mass seemed to resemble a pseudoaneurysm, as flow was recorded at duplex ultrasound examination (Figure 2).
Selective right internal carotid angiography confirming the presence of the voluminous pseudoaneurysm arising from the carotid bifurcation and extending toward the nearby parapharyngeal space.
