Endoscopic Removal of a Rare Case of Extranasopharyngeal Angiofibroma: A Case Report and Review Article

Abstract

Introduction: Angiofibroma is a benign, un-encapsulated, and highly vascular tumor which typically arises from the pterygopalatine fossa in the young adolescent males. It predominantly extends into the nasopharynx and rarely develops extranasopharyngeally. However, the most common origins of extranasopharyngeal angiofibromas are the maxillary sinus, ethmoid sinus and nasal cavity. Case Presentation: Here, we report a 40-year-old male who presented with headache and epistaxis and was diagnosed as an extranasopharyngeal angiofibroma originated from the sphenoid sinus. The tumor was completely resected endoscopically. The 24-month follow-up showed no recurrence. Conclusions: Angiofibromas should be considered as a possible diagnosis in any unilateral vascular mass of the nasal cavity, even in the older patients without typical imaging patterns.
