Preoperative Endovascular Embolization of Juvenile Nasopharyngeal Angiofibroma

The juvenile nasopharyngeal angiofibroma (JNA) comprises only 0.5% of head and neck neoplasms. This is a rare tumor, pathoanatomical characterized as benign vascular tumor with frequent localization in pterygopalatine fossa in adolescent males. Despite the absence of malignant nature, the juvenile nasopharyngeal angiofibroma is known to have locally invasive dissemination and progressive growth, which although rarely is associated with involvement of the intracranial space, with or without massive hemorrhage. The angiofibroma blood supply from the carotid system understandably draws the attention to the endovascular procedure focusing on its positive contribution to the treatment of such lesions. Besides being a “gold standard” in determining the feeding vessels, angiography serves as a main procedure in tumor treatment embolization prior the surgical excision.
