상악동에서 기원한 염증성 위종양 1례

초록

Inflammatory pseudotumor of the upper airway is a rare lesion, clinically mimicking a neoplastic process. It has no identifiable cause or associated systemic disease. It is thought to be a form of idiopathic pseudotumor and has been reported to occur most often in the lungs, conductive airways, and orbit. Its occurrence in the maxillary sinus is rare. Diagnosis of inflammatory pseudotumor of the maxillary sinus is a difficult pre-operatively. We present a case of 64 year-old female with an unusual inflammatory pseudotumor of the maxillary sinus that simulated an aggressive neoplasm on PNS CT. The difficulties in establishing this clinico-pathologic diagnosis are discussed.
