A Rare Case of Extra Nasopharyngeal Angiofibroma of the Ethmoid Sinus with Orbital Extension

Extra Nasopharyngeal Angiofibroma (ENPA) is very rare benign but locally destructive vascular tumor. We present a rare case of ENPA originating from anterior ethmoid in a 30 years old male presented with unilateral nasal obstruction and ipsilateral eye protrusion. Diagnosis of ENA was based on imaging modalities (CT scan and MRI) and biopsy of the mass. Endoscopic and external surgical approach were used to remove the mass completely. Recurrence of the disease occurred after eight months of surgical excision. Patient underwent Endoscopic removal of the mass. To best of our knowledge, only a few cases of ENPA originated from ethmoid sinus has been reported in the literature.
