Intracranial invasion of the nasopharyngeal angiofibroma is rare. A 14 years old male was admitted with complaints of nasal obstruction, frequent nasal bleeding, frontal headache, hearing impairment, exophthalmos, visual disturbance and vomiting, that were recently getting worse. A ovoid firm pinkish egg-sized mass in the nasopharynx and the both nasal cavity with bulging of the palate and the markedly retracted ear drum were noted in otolaryngological examinations. Decreased visual acuity (right 0.04 and left 30cm/finger count), both pale optic disc, right temporal hemianopsia and right lateral rectus palsy were observed in ophthalmologic examinations. There were the findings of displacement of sella and pituitary fossa with destruction of sphenoid and anterior and posterior clinoid, widened carotid siphon, elevation of first portion of anterior cerebral artery and tumor mass feeding from internal maxillary artery on the simple skull X-ray and the carotid angiogram. With transpalatal approach, 8×7×5cm sized on the vault of the nasopharynx with central cystic degeneration containing dark bloody fluid, was removed partially because of the bony defect of the sphenoid and skull base, which was confirmed histopathologically. On postoperative 2nd week, visual disturbance and field and hearing were improved but follow-up was missed.
