Abstract
Angiomatous nasal polyp (ANP) is a rare entity of inflammatory sinonasal polyp, constituting 4 to 5% of all nasal polyps1,2. Without knowledge of the typical clinical presentation and the complete study of imaging findings, the entity tends to be clinically and radiologically confused with neoplastic processes and even malignancy.5 Their diagnosis and management requires more detailed evaluation in respect to classical antrochoanal polyps. In both antrochoanal polyps and angiomatous nasal polyps, bone destruction is seen as a rare exceptional finding. We present an interesting case of angiomatous nasal polyp. CT finding also supported the clinical impression of neoplastic mass but biopsy was negative for malignancy. The biopsy confirmed the final impression of angiomatous nasal polyp.
Angiomatous antrochoanal polyps are rare variants that require special attention both at diagnosis and during surgery. The signs of bone destruction and epistaxis suggest additional pathologies including inverted papilloma, lobular capillary haemangioma and carcinoma as differential diagnoses.
