Juvenile angiofibroma (JNA) is a relatively uncommon, highly vascular and benign tumor that presents most commonly in adolescent males. Symptoms may persist from months to years and often times, these tumors are asymptomatic until they increase and encroach on critical structures. Because of technological advances both in surgery and radiology, management of JNA patients has been refined. With the advent of more sophisticated capabilities such as CT, MRI, intensity-modulated radiation therapy (IMRT), stereotactic guidance systems as well as advanced embolization techniques, these tumors can be diagnosed and managed more effectively.Patients with juvenile angiofibroma (JNA) are typically silent for years and often present with epistaxis, nasal obstruction, facial numbness, rhinorrhea, ear popping, sinusitis, cheek swelling, visual changes and headaches. In addition to these symptoms, up to one-third of patients with this condition may present with proptosis or other orbital involvement, which are late symptoms and findings.Most physicians agree that surgery is the primary treatment modality for the early-stage disease process. However, controversy arises regarding the best treatment when a patient presents with more locally advanced disease involving widespread cranial-based extension or intracranial involvement which may necessitate a combination of treatment modalities including surgery and postoperative radiation.With the advancement of endoscopic surgery, there have been a number of cases reporting the value of its use. The purpose of this review, however, will address not only endoscopic alternatives, but will discuss other treatment options as reported in the literature. Robotic surgery of the skull base for JNA is something to expect for the future.Finally, with the advent of IMRT and an image-guided robotic radiotherapy delivery system, some researchers speculate that this will result in less objections for radiation in general and certainly less reservations for the use radiotherapy in certain circumstances, i.e. patient refusal of surgery or extensive non-resectable or recurrent JNA tumors.

Angiofibromas are histologically benign, but unencapsulated and highly vascular tumors with a potential of local destructive effect. Angiofibromas predominantly originate from the posterolateral wall of the nasopharynx. Extranasopharyngeal angiofibromas are extremely rare and mostly seen in maxillary sinus and ethmoid sinus. In this article, we report a 21-year-old male case who was admitted with headache and diagnosed with an angiofibroma originating from the sphenoid sinus.

Female patients, 50 years old, have a recurrent unilateral aggravating headache for 5 years. Without runny nose, sneezing, nasal hemorrhage, smell or vision loss. Prefessional examination: there is a visible hoar neoplasm in the right middle nasal meatus With smooth surface and rich in vascular. The nasopharyngeal MRI shows that there is a occupancy lesion in the right nasal cavity and sinuses, well-demarcated, about 21. 5 mm x 25.5 mm x 37.0 mm. Angiofibroma is the most likely diagnosis. Postoperative pathological section shows that tumor are hypercellular, which contains big nucleus. Cells are spindle or short fusiform shape, there are stripes and nuclear division in some cells. There are vortex structures in partial region. Immunohistochemical examination shows: CD34(++), Ki-67 (< 5%), CD68(-), Des (-), NSE(+), S-100(++), SMA(-), EMA (+). Histopathologic diagnosis: atypical meningioma, some were differentiated to rhabdoid meningioma. The final diagnosis is malignant meningioma in nasal cavity and paranasal sinuses.
