Juvenile angiofibroma

Juvenile angiofibroma: Description, Causes and Risk Factors: A markedly vascular fibrous tumor occurring in the nasopharynx of males, usually in the second decade of life; epistaxis and local invasion may result, but spontaneous regression may occur after sexual maturity. Juvenile angiofibromaJuvenile angiofibroma is a rare vascular mass that usually develops in the backmost part of the nasal cavity, often but not exclusively, in adolescent males. Because of the significant blood flow through the tumors, their main presenting symptom is massive nosebleed, which is often recurrent. Because there is a mass in the back of the nasal cavity, there may be unilateral nasal obstruction or chronic nasal discharge. In certain instances these tumors push into surrounding normal regions and can put pressure on the eustachian tube, thus causing fluid to build up behind the eardrum, with a mild conductive hearing toss. Symptoms: • Difficulty breathing through the nose. • Easy bruising. • Frequent or repeated nosebleeds. • Hearing loss. • Nasal discharge, usually bloody. • Prolonged bleeding. • Stuffy nose. Diagnosis: Diagnosis begins with the history and physical examination. An abnormal mass can often be seen at the back of the nasal cavity. Imaging tests, such as a cranial CT or cranial MRI are often done to show the tumor's size and location. The doctor may see the angiofibroma when examining the upper throat. Tests that may be done include: • Arteriogram to see the blood supply to the growth. • CT scan of the head. • MRI scan of the head. • X-ray. • Biopsy is generally not recommended due to the high risk of bleeding. Treatment: Treatment is required if the angiofibroma is growing larger, blocking the airways, or causing repeated nosebleeds. In some cases, no treatment is necessary. Surgery may be needed to remove the tumor. Removal is often difficult because the tumor is not enclosed and may have spread deeply to other areas. A procedure called embolization may be done to prevent the tumor from bleeding. The procedure may correct the nosebleeds by itself, or it may be followed by surgery to remove the tumor.
