EpidemiologyClinical PresentationPathologyRadiographic FeaturesTreatment and PrognosisDifferential DiagnosisJuvenile nasopharyngeal angiofibromas occur almost exclusively in males and usually in adolescence (~15 years) They account for only 05% of all head and neck tumors 2but are the most common of the benign nasopharyngeal neoplasms The presentation is typical with obstructive symptoms epistaxis and chronic otomastoiditis due to obstruction of the Eustachian tube Patients may present with lifethreatening epistaxis On examination it may be seen as a pale reddishblue mass It is as the name suggests very vascular and a biopsy can sometimes be fatal Juvenile nasopharyngeal angiofibromas are benign but highly vascular tumors They may be locally aggressive The exact site of origin is contentious as these masses usually present when they have reached a considerable size However most authors agree that they arise from the posterior choanal tissues in the region of the sphenopalatine foramen See staging of juvenile nasopharyngeal angiofibromas Imaging plays an important role in diagnosis as well as staging as biopsies should be avoided due to the risk of brisk hemorrhage due to the tumor&#39s vascular nature Although these masses are thought to arise from the region of the sphenopalatine foramen they are usually sizable at diagnosis frequently with extension medially into the nasopharynx laterally into the pterygopalatine fossa and over time beyond into the orbit paranasal sinuses intracranial cavity and infratemporal fossa Plain radiographs no longer play a role in the workup of a suspected juvenile nasopharyngeal angiofibroma however they may still be obtained in some instances during the assessment of nasal obstruction or symptoms of sinus obstructions Findings include 3 1 visualization of a nasopharyngeal mass 2 opacification of the sphenoid sinus 3 anterior bowing of the posterior wall of the maxillary antrum (HolmanMiller sign) 7 4 widening of the pterygomaxillary fissure and pterygopalatine fossa Surgical resection (either open or increasingly endoscopic) is the treatment of choice usually performed after preoperative embolization to help with hemostasis The embolization may be performed up to five days prior to surgery Irradiation may be an option if surgery is not possible or only incomplete resection has been achieved 246 In cases where there is skull base involvement a high recurrence rate (up to 50%) has been reported 24 Imaging differential considerations include 1 angiomatous polyp variant of a sinonasal polyp located toward ostium/hardly extend to the nasopharynx elderly age less vascularity 2 rhabdomyosarcoma (head and neck) 3 nasopharyngeal carcinoma (NPC) 4 nasopharyngeal teratoma 5 nasopharyngeal lymphoma 10 6 lymphangioma no contrast enhancement 7 encephalocele no contrast enhancement 8 esthesioneuroblastoma.
