Abstract：Objective: To improve the understanding of CT imaging features of tuberculous lymphadenitis. Materials and Methods: Twenty-one cases of tuberculous lymphadenitis after pathologically confirmed, including 7 men and 14 women, the average age was 32 years(range from 18～67 years) were studied, all patients underwent enhanced CT scan. Results: Twenty-one patients with different parts of cervical, mediastinal and abdominal lymph node tuberculosis. The CT features could be divided into five types: ①iso-density enhancement; ②heterogeneous enhancement; ③corolla-like enhancement; ④separate ring-like enhancement; ⑤integration of multi-ring-like enhancement. Two or more features mixed together were seen in 16 cases. Eighteen cases showed various ring enhancement, accounting for 85.7%, a separate ring-like enhancement and/or integration of multi-ring-like enhancement were the most characteristic features. Conclusion: CT had certain characteristics of tuberculous lymphadenitis, and was the preferred method for diagnosing this disease.
