title: Imaging Features of Sinonasal Inverted Papilloma: A Pictorial Review.
abstract: Computed tomography and magnetic resonance imaging are widely used for evaluation of patients with nasal masses, playing an integral role in their diagnosis and treatment. Inverted papilloma is a rare tumor of the sinonasal region that demonstrates characteristic imaging appearances. Preoperative diagnosis and precise tumor extent are essential for surgical planning as this tumor grows centrifugally and has high potential to recur following incomplete surgery. This pictorial review aims to illustrate the spectrum of imaging features of inverted papilloma and highlight the key features that are useful for making an accurate diagnosis of this condition. Common differential diagnoses are also discussed.
