Frontoethmoidal Extranasopharyngeal Angiofibroma With Orbital Pyocele

Abstract

Significance Statement Extranasopharyngeal angiofibromas (ENA) are rare vascular tumors that do not conform to the clinical characteristics of typical nasopharyngeal angiofibromas. We present the management of an angiofibroma in a rare site, within the frontal sinus with a concomitant orbital pyocele, which was completely excised via an endoscopic approach. ENAs should be considered as a differential diagnosis in patients with sinonasal mass and epistaxis. Awareness of this rare entity will avoid radical surgery thus decreasing postoperative morbidity.

Bilateral Frontal Sinus Ectopic Angiofibroma: Focus on Management of a Rare Lesion with Unusual Presentation

“…Extranasopharyngeal Angiofibromas (ENA) involving paranasal sinuses represent an unusual finding and the localization at the level of frontal sinus is an extremely rare event with few cases reported in literature [1,2]. The clinical presentation is aspecific, lacking the typical features of their more common naso-pharyngeal counterpart with which they share the histological characteristics.…”

Current approach of juvenile nasopharyngeal angiofibroma: a case series

“…Even though the microscopic structure is representative of a benign tumor, JNA frequently displays aggressive characteristics through its invasion of neighboring structures: the nasal turbinates, the nasal septum, the pterygopalatine fossa, the sphenoid, ethmoid and maxillary sinuses [9,10]. In severe cases of JNA, when the tumor is neglected, it may invade the orbit or the neurocranium [11][12][13].…”
