Abstract :

Tuberculous lymphadenitis is the most common extra pulmonary manifestation of tuberculosis. FNAC and Ziehl Neelson staining of FNA samples have low specificity and sensitivity respectively. The aim of this study is to correlate the cytomorphological pattern of the lymph nodes with CB–NAAT as an aid to the diagnosis of tuberculous lymphadenitis. Materials and methods–A retrospective study of 58cases were undertaken from January2019 to Decamber2019 in RIMS Ranchi, a tertiary care centre .Result– Out of the total 58cases 52 samples could be run on CB–NAAT. Out of the total cases run [56%] were CB–NAAT positive. The cytomorphological pattern, Necrosis without epithelial aggregates showed the maximum positivity of MTB CB–NAAT being [35%] . The preponderance of males and age group between 21to 30 years was the highest [57%]. Rifampicin resistance was seen in [14%] of cases.
