Hemangioma of the Maxillary Sinus Presenting as a Mass: CT and MR Features

Hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhancing areas within the tumor, the substantial bone erosion and remodeling made it difficult to differentiate this cavernous hemangioma from other expansile maxillary sinus lesions. we present the ct and mr findings of this lesion and discuss the differential diagnoses and potential therapeutic approaches.
