Maxillary sinus cavernous hemangioma: a rare entity.

Vascular lesions of the sinonasal tract are rare. These lesions do not have typical signs or symptoms. They may present insidiously with minimal symptoms. A high index of suspicion and a good preoperative evaluation are needed for diagnosis. No standard surgical approach is indicated. We report a case of cavernous hemangioma of the maxillary sinus in an adult male. We present the diagnostic work-up and discuss the differential diagnosis and potential therapeutic approaches.
