Introduction: Ultrasonography (USG) helps by detecting lesions, giving idea about its internal structure and also gives opportunity to evaluate other abdominal organs. However, evaluation by CT scan can give additional information which can modify the course of treatment and/or suggest prognosis of the patient. Methodology: 84 patients were included, evaluated with USG and CT scan of abdomen and pelvis. Ovarian pathologies were categorized as benign, malignant and metastasised and the results of CT and USG were compared. Results: 84 patients were evaluated. The disease prevalence of malignant lesions was 55.95% on USG and 54.76% on CT Scan. CT Scan was more sensitive (97.8%) than USG (85.1%) but sonography (94.5%) was more specific than CT Scan (92.1%). USG had higher positive predictive value (95.2%) as compared to CT Scan (93.7%) to diagnose malignant lesions. But negative predictive value of CT Scan (97.2%) was higher than USG (83.3%) to rule out malignant lesions. Conclusion: CT scan and sonography are comparable in differentiating malignant from benign ovarian tumors. CT scan was more sensitive than USG, but sonography is more specific than CT scan in diagnosis of malignant lesions. USG has high positive predictive value as compared to CT scan to diagnose malignant lesions.
