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.
