Radiological Diagnosis of Nasopharyngeal Non-Hodgkin's Lymphoma

  • Objective: To investigate the radiological findings of nasopharyngeal non-Hodgkin's lymphoma(NHL). Materials and Methods: The CT images of 22 patients and MRI images of 6 patients with pathologically confirmed nasopharyngeal NHL were retrospectively analyzed. All nasopharyngeal NHL were assessed for morphology,necrosis,local invasion and lymphadenopathy. Results: 16 cases presented the walls of nasopharynx symmetrically or general symmetrically diffuse thickening, and 12 cases presented soft tissue masses on the hanging posterior and(or) lateral walls of nasopharynx. 25 cases were homogeneous. 14 cases invaded the oropharynx, palatine and/or lingual radix tonsil swollen in 4. 2 invaded the laryngopharynx. 4 invaded nasal cavity. 1 invaded clivus and adjacent muscles. Lymphadenopathy was found in 17, with necrosis in 4. Conclusions: There were typical features of nasopharyngeal NHL on MRI or CT. Nasopharyngeal NHL usually invaded mutiple walls of nasopharynx, and more than half were lymphadenopathy. Both of the tumour at nasopharynx and lymphadenopathy were homogeneous, necrosis uncommon. Skull base or the deep structures invasion were rare. The lesions could spread down invading the other parts of Waldeyer ring.
