Juvenile nasopharyngeal angiofibroma (JNA) is a relatively uncommon, benign neoplasm of the nasopharynx that can be very difficult to diagnose early due to inconspicuous and seemingly harmless presenting symptoms. Early diagnosis and treatment of JNA are essential for a good prognosis. JNA typically responds well to radiation therapy (RT), but when it does not, the most appropriate next course of action has not been readily defined due to the limited occurrence and experience with this neoplasm. Herein, we describe a JNA patient, who continued to progress after surgery and 36 Gy of adjuvant radiation, but after an additional 14.4 Gy, he has remained in remission for over 2 years. An 11-year-old boy who presented with JNA underwent treatment with embolization and surgical resection. Unfortunately, the tumor progressed within 2 months of surgical intervention and he required RT for adequate local control. While undergoing RT, he again demonstrated signs of progression; so his radiation regimen was increased from 3,600 cGy in 20 fractions to 5,040 cGy in 28 fractions. Since completing RT, the tumor has continued to decrease in size, and the patient is stable and has been without signs of disease progression for over 24 months now. Thus, escalating the radiation regimen to 5,040 cGy may improve local control in rapidly progressive JNA.
