Sinonasal angiomatous polyp (SAP) is a benign pseudoneoplastic lesion rarely reported in the literature. It may be misdiagnosed as a malignant neoplasm due to its aggressive features of bone erosion clinically or on imaging. We report the case of a 43-year-old woman with a 3 month history of unilateral nasal obstruction with recurrent epistaxis. Nasal endoscopy showed polypoid nasal mass occupying the left nasal cavity. Imaging was suggestive of malignant vascular tumor. The patient underwent surgical excision after embolization. Histopathology concluded to the diagnosis of SAP.
