Methods Ultrasonography of the neck nodes was carried out prior to FNAC in 192 patients using a 10 mHz linear transducer. The sonographic findings were then correlated with the definitive tissue diagnosis obtained by FNAC or lymph node biopsy. Results The most significant distinguishing feature was strong internal echoes seen in 84 of tubercular lymph nodes. This finding was found in only 11 of metastatic nodes and absent in lymphomatous nodes. The other findings such as L S ratio irregular margins hypoechoic center fusion tendency peripheral halo and absent hilus were helpful in differentiating reactive from diseased nodes but showed considerable overlap in the 3 groups of tubercular metastatic and lymphoma lymph nodes. Conclusion Ultrasonography is noninvasive and can give useful clues in the diagnosis of cervical lymphadenopathy. It should be interpreted in conjunction with FNAC result. Ideally ultra-sonographic guided FNAC should be obtained from the sonographically most representative node. In FNAC indeterminate cases sonographic features may obviate the need for an invasive lymph node biopsy. Introduction Cervical lymph nodes are frequently involved in a number of disease conditions. The most commonly seen causes of cervical lymphadenopathy are tuberculosis distant metastasis and lymphoma. Fine needle aspiration cytology is used for evaluating enlarged cervical lymph nodes and has a high degree of sensitivity and specificity. However in our experience in almost 20 of patients FNACs may give an equivocal report .
