The efficacy of the fine needle aspiration biopsy and cytological examination (FNABC) under ultrasonographic (US) guides for the diagnosis of cervical tuberculous lymphadenitis was assessed. In one hundred and one patients with a neck mass or masses, tuberculous lymphadenitis has been proved by FNABC. US disclosed the physical characteristics of the masses: All the cases that involved two or more lymph nodes were multiple lesions. Eighty lesions (79.1%) were multiregional, and in 19 cases (18.8%), bilateral neck was involved. The posterior triangle of the neck was the most prevalent site (N = 69, 68.3%). Ninety two cases (90.9%) were hypoechoic lesions and 9 (9.1%) showed mixed echo patterns. There was no hyperechoic lesion (p< 0.001). The sensitivity of FNABC was 77.2% and the specificity was 99.0%. The diagnostic accuracy was 85.0%. There was no complication during the procedure. FNABC for the diagnosis of cervical tuberculous lymphadenitis is a safe, convenient procedure and has a relatively high specificity. The limitation of FNABC, the low sensitivity, seemed to be compensated by US examinations.

OBJECTIVE: Although tuberculous lymphadenitis and Kikuchi disease are common causes of cervical lymphadenopathy in Asians and exhibit similar clinical manifestations, their treatment strategies are totally different. The purpose of this study was to identify ultrasonographic features that distinguish these two diseases. MATERIALS AND METHODS: This study was approved by the Institutional Review Board. The study included 77 patients with tuberculous lymphadenitis and 135 patients with Kikuchi disease. The sex and age distributions of the patients were analyzed. The size and shape of lymph nodes (LNs), presence of conglomeration, increased perinodal echogenicity, echogenic hilum, posterior neck involvement, internal calcification, patterns of internal necrosis, laterality of involved LNs, and hilar vascular patterns on ultrasonography were compared between the two groups. Multiple logistic regression analysis was conducted to identify independent findings to discriminate tuberculous lymphadenitis from Kikuchi disease. Finally, diagnostic accuracies were calculated using the independent findings. RESULTS: The presence of an echogenic hilum, internal calcification, patterns of internal necrosis, and LN hilar vascular structures on power Doppler ultrasonography were independent findings that discriminated tuberculous lymphadenitis from Kikuchi disease. The diagnostic accuracy of each of these four factors was 84.9% (181/212), 76.9% (163/212), 84% (178/212), and 89.2% (189/212), respectively. A combination of internal calcification and hilar vascular structures showed the best accuracy of 89.6% (190/212) (sensitivity, 86.7% [117/135]; specificity, 94.8% [73/77]) for diagnosing Kikuchi disease. CONCLUSION: The presence of an echogenic hilum, internal calcification, pattern of internal necrosis, and LN hilar vascular structures are useful ultrasonographic findings to differentiate tuberculous lymphadenitis from Kikuchi disease.
