Extranasopharyngeal angiofibroma

Abstract

Juvenile nasopharyngeal angiofibromas are vascular neoplasms, which originate characteristically in the posterior lateral wall of the nasopharynx. Although angiofibromas extend beyond the nasopharynx commonly, they rarely originate outside the nasopharynx. Reports of primary extranasopharyngeal angiofibromas have appeared sporadically in the literature. We present an unusual case of an angiofibroma arising from the middle turbinate. The clinical characteristics of extranasopharyngeal angiofibromas do not conform to that of nasopharyngeal angiofibromas. Therefore, they can present diagnostic challenges. A methodic evaluation and a high index of suspicion are essential in establishing the proper diagnosis and treatment.

Juvenile nasopharyngeal angiofibroma—our experience at a referral hospital

“…Extranasopharyngeal angiofi broma is very rare. However, angiofi broma arising from the middle turbinate [9] and from the nasal septum [10] has been reported. Chagnaud et al [11] assessed the radiological fi ndings after the surgical removal of juvenile nasopharyngeal angiofi broma and found dramatically enhanced mass on early postoperative CT or MRI.…”

Angiofibroma from the Tail of the Inferior Turbinate

“…Surgical excision remains the mainstay of treatment for extranasopharyngeal angiofibromas [3]. In our case, the size and the location of tumor permitted us to remove it completely, using a simple endoscopic surgical procedure, without previous selective arteriography and embolization.…”

“…These tumors may rarely localize in extranasopharyngeal sites [1]. The maxillary sinus being the most commonly involved site [3]. The inferior turbinate represents an extremely rare localization with only 4 cases having been reported in the international literature to date.…”

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

“…Depending on their location, they can cause seizures, focal neurological deficits, symptoms of obstructive hydrocephalus, visual field impairment, behavioral disorders, or symptoms of increased intracranial pressure. 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].…”
