Abstract

Here in, we report two cases of organized hematoma in the maxillary sinus mimicking inverted papilloma. These cases presented as heterogeneously enhancing, expansile masses on computed tomography and magnetic resonance imaging, and also evidenced mild uneven hypermetabolism on positron emission tomography-computed tomography. Organized hematoma should be included in the differential diagnosis of inverted papilloma.

기질화 혈종과 반전성 유두종은 모두 상악동에 발생하는 종괴로, 영상의학적 소견이 유사하여 주의 깊은 감별을 요한다. 저자는 컴퓨터단층촬영 및 자기공명영상에서 팽창성 종괴로 이질적 조영증강을 보이며, 양전자방출단층촬영술에서 약간의 비균질 대상항진을 보이는, 반전성 유두종과 감별이 어려운 기질화 혈종의 두 증례를 경험하였기에 이를 보고하고자 한다.
