Image-guided fine-needle aspiration cytology of ovarian tumors: An assessment of diagnostic efficacy

Abstract

Background:Image-guided fine-needle aspiration cytology (FNAC) of ovarian lumps is being increasingly used for the successful diagnosis of ovarian tumors, although borderline cases may be difficult to diagnose by this method.Aim:To demonstrate the efficacy of image-guided FNAC in diagnosing ovarian tumors (benign and malignant) and to evaluate the usefulness of cytology as a mode of easy and rapid diagnosis of ovarian lumps.Materials and Methods:The study was conducted on 42 female patients. Clinical evaluation and relevant investigations were carried out. Diagnosis was established by FNAC performed under image guidance (ultrasonography/computed tomography). The cytological diagnosis was confirmed by histopathological examination.Results:Cytological diagnosis was rendered on all the 42 ovarian lesions, with a correct diagnosis in 34 cases, resulting in a diagnostic accuracy of 80.9%. Most of the cases with discordant diagnoses were surface epithelial tumors of low malignant potential and required histopathological examination for a final diagnosis.Conclusions:Image-guided FNAC is an inexpensive, rapid and fairly accurate procedure for the diagnosis of ovarian lesions. It provides a safe alternative to the more expensive, time consuming and cumbersome surgical route to diagnosis.
