Ultrasonography (USG)-guided fine-needle aspiration cytology (FNAC) of ovarian masses is an efficient diagnostic modality for accurately diagnosing ovarian tumours prior to surgery. The main aim of this study was to assess the sensitivity, specificity and accuracy of FNAC in diagnosing ovarian masses.


Eighty-three patients with ovarian masses were recruited and correlation of USG-guided FNAC was made with histopathology in all but 6 cases, where surgery was not indicated.


Cytological diagnosis was obtained in all 83 ovarian lesions: 56 cases were benign, 6 possibly benign, 3 suspicious of malignancy and 18 cases as malignant. Out of 77 cases where histology was available, the 12 non-neoplastic cysts were endometriotic cysts and follicular cysts. The majority of neoplastic lesions were surface epithelial tumours. Out of 12 non-neoplastic cysts and 43 benign tumours, all but two were diagnosed as benign or possibly benign on cytology; of the 22 histologically malignant or borderline tumours, 18 were malignant or suspicious of malignancy on cytology, while four were false negative (three of these were borderline tumours). Thus, the sensitivity of cytological diagnosis was 83%, specificity was 97% and accuracy was 93%.


USG-guided FNAC seems to be a relatively safe, simple, fast and cost-effective procedure where most ovarian malignancies either present late in their course or no screening method is available. In addition, cyto-radiological correlation through this procedure may be useful in deciding management guidelines prior to any surgical intervention.
