Imaging predictors for malignant transformation of inverted papilloma

Abstract

Inverted papillomas (IPs) are benign tumors of the sinonasal tract with a malignant transformation potential. Predicting the transformation propensity of IPs and corresponding risk factors has long been a challenge. In this study, we aimed to use radiographic findings on magnetic resonance imaging (MRI) and computed tomography (CT) to help differentiate IP from IP‐transformed squamous cell carcinomas (IP‐SCC).
