Axial CECT showing CCA proximal to its bifurcation.

A 24-year-old female presented with painless, slowly enlarging mass lesion at the angle of mandible on right side of 14 months duration. There was no history of dysphagia/ hoarseness/ headache. She did not have symptoms or signs of Horner’s syndrome or catecholamine excess. Her past medical history was insignificant and there was no family history of similar complaints.

The patient was moderately built and her general physical examination was unremarkable except for pallor. Her vitals were within normal limits. On local examination, there was an ovoid, firm, non-tender, pulsatile mass lesion, 3 x 1.8 cm size, located along the anterior border of sternomastoid at the level of hyoid bone on right side. The swelling was freely movable laterally than vertically (Fontaine’s sign positive). There was no audible bruit or palpable lymph nodes.
Routine lab investigations were normal.
