To assess the usefulness of ultrasonography in the differential diagnosis of cervical tuberculous lymphadenitis versus malignant lymph nodes. Ultrasonography of cervical lymph nodes was performed with a real‐time linear scanner using a 7.5‐ or 11‐MHz probe or both. Ultrasonographic findings were retrospectively reviewed in 73 patients: 49 with malignant lymphoma, 15 with tuberculous lymphadenitis, and 9 with metastatic lymph nodes. Ultrasonographic features specific to cervical tuberculous lymphadenitis were strong echoes (33.3%) and an echogenic thin layer (86.7%). When the lymph nodes had at least 1 of these 2 features, tuberculous lymphadenitis was diagnosed with a sensitivity of 100% and a specificity of 100%. Ultrasonographic evaluation of cervical lymph nodes can be useful in the diagnosis of cervical tuberculous lymphadenitis.
