Utility of Preoperative Ultrasonography and Fine-Needle Aspiration Cytology in Differentiation Between Benign and Malignant Cervical Lymphadenopathy: A Retrospective Cohort Study

The preoperative differentiation of benign form malignant cervical lymphadenopathy (CLA) is crucial in determining the need for surgical intervention. This study aims to assess the diagnostic performance of ultrasonography (US), fine-needle aspiration cytology (FNAC), and their combination with the postoperative histopathological diagnoses of CLA.
