Abstract
INTRODUCTION: Lymph nodes are normal structures distributed throughout the human body and are enlarged in various disease entities. Identifying the relevant lymph nodes is important in treating these patients. High resolution sonography (HRSG) and fine needle aspiration cytology (FNAC) play crucial role in planning the treatment. OBJECTIVE: To assess the diagnostic accuracy of HRSG differentiate neoplastic and non neoplastic causes of enlarged cervical lymph nodes. MATERIALS AND METHODS: HRSG evaluation of enlarged cervical lymph nodes were performed to differentiate neoplastic from non neoplastic lymph nodes followed by FNAC correlation and the accuracy of HRSG was studied. RESULTS: One hundred and fourteen lymph nodes of 106 patients were analysed to accomplish the study objective. In our study, HRSG had 96% sensitivity and 90.6% specificity for differentiating between neoplatic and non-neoplastic cervical lymphadenopathy. Similarly positive and negative predictive values were 88.9% and 96.7% respectively. Overall accuracy of HRSG was 93%. CONCLUSION: Owing to high sensitivity and negative predictive value, HRSG with Doppler is an excellent first line investigating tool for enlarged lymph nodes and avoids invasive procedures like FNAC in cases of reactive/ inflammatory (non-neoplastic) lymph nodes. However, neoplastic diagnosis of HRSG needs further confirmation by FNAC.
