Abstract:
Juvenile nasopharyngeal angiofibroma (JNA) is a benign but locally aggressive vascular tumor that affects young males. Biopsy of this highly vascularized lesion is inadvisable. This case illustrates a patient with JNA who underwent a biopsy, resulting in severe bleeding, highlighting the importance of differentiating JNA from more common conditions with similar symptoms. A multidisciplinary approach is essential, and endoscopic resection is the cornerstone of treatment, often involving preoperative MRI with angiography and embolisation to minimise blood loss and improve outcomes.
