Juvenile nasopharyngeal angiofibroma (JNA) represents a rare, histologically benign yet locally aggressive vascular tumor that predominantly arises in adolescent males. Given its propensity for invasive growth and involvement of critical anatomical structures, precise radiological evaluation is vital prior to any intervention. We present the case of a 13-year-old male who experienced progressive bilateral nasal blockage and recurrent epistaxis predominantly on the left side. Magnetic resonance imaging (MRI) identified a vividly enhancing lesion centered at the left sphenopalatine foramen, with extensions into adjacent sinuses, the pterygopalatine fossa, infratemporal fossa, and early skull base erosion. This case highlights the critical diagnostic and staging role of MRI in JNA, illustrating how characteristic imaging findings inform diagnosis, classification, and surgical planning.
青少年鼻咽血管纤维瘤（JNA）是一种罕见的、组织学上为良性但具有局部侵袭性的血管肿瘤，主要发生于青春期男性。鉴于其有侵袭性生长的倾向并累及重要解剖结构，在进行任何干预之前，精确的放射学评估至关重要。我们报告一例13岁男性病例，该患者主要表现为进行性双侧鼻塞，以左侧为主，并反复鼻出血。磁共振成像（MRI）显示一个以左侧蝶腭孔为中心的明显强化病变，病变延伸至相邻鼻窦、翼腭窝、颞下窝，并早期侵犯颅底。该病例突出了MRI在JNA诊断和分期中的关键作用，展示了典型的影像学表现如何为诊断、分类和手术规划提供依据。
