Inflammatory Myofibroblastic Tumor of the Nose and Paranasal Sinuses Masquerading as a Malignancy

Inflammatory myofibroblastic tumor (IMT) of the nose and paranasal sinuses is a rare entity that exhibits a diverse histologic pattern that can mimic malignant tumors clinically and radiologically. We present a case of IMT in an 88-year-old man who presented with an aggressive tumor-like lesion in the nose and paranasal sinuses that had a malignant appearance on radiology. We discuss this tumor's clinicoradiologic resemblance to a malignancy, and we review the treatment options following careful histologic and immunohistochemical analysis.
