Atypical Clinical and Radiological Presentation of Juvenile Nasopharyngeal Angiofibroma; A case report

Juvenile nasopharyngeal angiofibroma (JNA) is a highly aggressive locally invasive vascular neoplasm found almost exclusively in prepubescent and pubescent boys. It accounts for 0.05% of all head and neck tumors and is the most common benign tumor involving the pterygopalatine and infratemporal fossa[1]. Although histologically benign, it is locally invasive and, if left untreated, has the potential to erode through the skull base[2]. Here we present a case report of a 13 years old boy came with history of obstruction in the right nasal cavity associated with epistaxis and discharge. Computed tomography with contrast imaging revealed an enhancing heterogeneous mass lesion in the nasopharynx and posterior choana extending to pterygopalatine and infratemporal fossa in the right side.
