Inflammatory pseudotumor is an uncommon nonneoplastic lesion of unknown etiology that occurs most commonly in the lung. However, it also occurs in diverse extrapulmonary locations: abdomen, retroperitoneum, pelvis, heart, head and neck, upper respiratory tract, trunk bladder, and extremities. The extrapulmonary inflammatory
pseudotumor is often larger, less-well circumscribed and multinodular. Proximity of the tumor to vital structures or involvement of vital organs compromises the opportunity for complete resection; thus higher recurrence rates are often reported even after surgical treatment. The authors report a case of inflammatory pseudotumor originating from
common carotid artery in a 42-year-old female patient with a rapidly growing neck mass, treated by en bloc resection of inflammatory pseudotumor and a long segment of common carotid artery followed by polytetrafluoroethylene(PTFE) graft interposition.
