What is the classic triad of radiological findings associated with nasopharyngeal carcinoma?

The classic triad includes: (1) a mucosal mass in the lateral nasopharynx, particularly in the fossa of Rosenmüller, (2) enlarged lateral retropharyngeal lymph nodes, and (3) opacification of the mastoid air cells due to eustachian tube dysfunction. Key diagnostic features include asymmetric soft tissue mass on MRI or CT and possible skull base erosion. Clinical pearls: Be aware of the association with Epstein-Barr virus and its higher prevalence in certain ethnic groups. Common pitfalls include mistaking benign lymphoid hyperplasia for malignancy.
