We compared 13 patients(19 lesions)with cystic lymph node metastasis of HPV-positive oropharyngeal carcinoma(CLM-HPV-OPC)and 9 patients(21 lesions)with tuberculous lymphadenitis(TL)regarding age, sex, CT findings, and textural parameters. Patients with TL was significantly younger than patients with CLM-HPV-OPC(p=0.04). Level 1b, 4, and 5 lesions were more commonly involved in TL(p=.005-.04)and level 2 lesions were more commonly involved in CLM-HPV-OPC(p<.001). Of the 41 measured texture parameters, significant differences were found in 12 ones. Although differential diagnosis between TL and CLM-HPV-OPC might be difficult on CT, age and involved lymph node level, and some texture parameters could help differential diagnosis.
