title: Involution of juvenile nasopharyngeal angiofibroma with intracranial extension. A case report with computed tomographic assessment.
abstract: In September 1979 the patient, a man born in 1964, noticed pain and swelling of the right cheek in combination with periods of epistaxis. A computed tomographic scan revealed a tumor extending from the middle of the right nasal cavity into the right maxillary antrum and up toward the orbital floor with destruction of the medial and lateral walls of the antrum and continuing into the sphenoid sinus on the right side and dorsal to the pterygoid process up under the base of the skull. Angiography showed arterial supply mainly from the right external carotid artery, but also from the right internal carotid artery and the left external carotid artery. The process was diagnosed as a juvenile nasopharyngeal angiofibroma. In spite of two attempts at resection of the tumor and arterial embolization, the tumor progressed intracranially. Further operative attempts were decided against, and the patient was followed with repeated computed tomographic scans. The tumor eventually became involuted; eight years after the initial diagnosis, there was no evidence of computed tomographic scans of intracranial growth of the tumor.
