Extranasophryngeal Angiofibromas (Sex incidence and age distribution)

Rare Infratentorial and Supratentorial Localization of Juvenile Angiofibroma: A Case Report

“…The most common primary extranasopharyngeal site for these tumors is the maxillary sinus [25]. Other common extranasopharyngeal sites include ethmoid and sphenoid sinuses, nasal septum, frontal recess, middle and inferior turbinates, tonsils, parapharyngeal space, ear, trachea, larynx, middle cranial fossa, infratemporal fossa, retromolar region, and conjunctiva [3]. …”

“…MRI is primarily used to determine the tumor site and its extension. Using MRI, skull base involvement, intracranial spread, and relationship to different important vascular and neurologic structures can be thoroughly assessed [3,25]. T1-weighted MRI will show a typical ‘salt and pepper' appearance caused by the increased vascularity of the tumor.…”

“…Nasopharyngeal angiofibromas (NAs) originate from the region of the sphenopalatine foramen and enlarge to fill the postnasal space. Because of the close proximity to the nasopharynx and the ease with which they invade this site, they are also commonly referred to as NAs [3]. About 0.5% [4,5] of all head and neck neoplasms are NAs and they predominantly occur in adolescent males, although they have also been reported in children aged <10 years [6,7,8,9,10,11,12,13,14] and in elderly [15], female [16,17,18], and pregnant [19] patients.…”

Surgical Neuroangiography

“…Fu, in 1974, diagnosed 38 (15%) JAF among 256 non-epithelial tumors of the nasal and paranasal cavities and nasopharynx. This differentiation does not in general seem to inferfere with the practical management of these lesions but they should be considered as separate entities (Ali 1982) (see other nasopharyngeal tumors). Tapia Acuna (1976), in Mexico, saw 279 cases in 22 years and 15 new cases in the first three months of 1970, suggesting the presence of an unidentified epidemiologic factor.…”

“…Over 36 cases have been reported since 1936, with a mean age of22 years (Ali 1982. Over 36 cases have been reported since 1936, with a mean age of22 years (Ali 1982.…”
