Management of Angiomatous Antrochoanal Polyp: Our Experience


Antrochoanal polyps are the most common type of choanal polyp. Angiomatous polyp is a rare subtype of Antrochoanal polyp that might be misdiagnosed as malignant lesion due to its clinical features. A retrospective observational study was conducted in a tertiary care hospital in patients who were diagnosed with Angiomatous Antrochonal polyp that underwent functional endoscopic sinus surgery from 2017 to 2020. We analyzed the clinical symptoms, radiological findings, and pathological features of all patients diagnosed with Angiomatous Antrochonal polyp. Unilateral nasal obstruction, rhinorrhea, and epistaxis were the common symptoms. Antrochoanal polyps all originated from maxillary sinus and extended to nasal cavity with or without involving the nasopharynx. Expansile mass with surrounding bony destruction are typical on computed tomography imaging but specific for Angiomatous Antrochoanal polyp. The magnetic resonance revealed high signal intensity on T1-weighted images and hypo-intense rim on T2-weighted images. Computed tomography and magnetic resonance together might give rise to more accurate diagnosis of Angiomatous Antrochoanal polyp. Incisional biopsy does help if the clinician suspects a malignant lesion. Complete removal is treatment of choice for Angiomatous Antrochoanal polyp.
