Potentially Distinctive Features of Sinonasal Inverted Papilloma on MR Imaging

The objective of this study is to describe potentially distinctive MR features of sinonasal inverted papilloma and those of coexisting squamous cell carcinoma. A sinonasal mass with a convoluted cerebriform pattern on T2- or enhanced T1-weighted images suggests inverted papilloma as a histologic dia...

Zusammenfassung:	The objective of this study is to describe potentially distinctive MR features of sinonasal inverted papilloma and those of coexisting squamous cell carcinoma. A sinonasal mass with a convoluted cerebriform pattern on T2- or enhanced T1-weighted images suggests inverted papilloma as a histologic diagnosis. Necrosis in a mass with such an appearance strongly suggests coexistent carcinoma.
