Radiotherapy for recurrent juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare paediatric tumour known for its local destructiveness and high recurrence rate. Surgery is the primary treatment modality for JNA, though other options, such as hormonal therapy, embolisation and radiotherapy, exist for inoperable cases. The location of the tumour makes surgical intervention challenging. A 14-year-old male presented with epistaxis and headaches as the chief complaints and was diagnosed with nasopharynx angiofibroma by computed tomography (CT) scan in 2018. Pre-operative embolisation was performed and followed by surgical removal of a 4 cm tumour in January 2019. Pathological examination revealed CD34 positivity, S100 negativity and Ki-67 positivity (5 to 10%), confirming angiofibroma. In October 2019, a 3.6 cm recurrent tumour was treated with embolisation and a second surgery. Pathological findings again confirmed JNA. The patient underwent four surgeries in total, but epistaxis persisted. In 2021, local radiotherapy was administered using intensity-modulated radiation therapy (IMRT) at a dose of 60 Gy in 25 fractions. Serial magnetic resonance imaging (MRI) post-radiotherapy showed a decreasing tumour size, with no further epistaxis and no observed radiation side effects 2 years post-treatment. Radiation therapy remains a strong alternative for managing recurrent JNA.
