Objective: Discrimation between benign and malignant ovarian mass is very important preoperatively for appropriate patient management. International Ovarian Tumour Analysis (IOTA) group in 2008 proposed a standardised method for preoperatively diagnosis of ovarian mass by its 10 simple ultrasound based rules to discriminate between benign and malignant ovarian tumour. This study was designed to evaluate the e icacy of simple ultrasound rules by IOTA group to discriminate between benign and malignant ovarian tumour. This study was designed to evaluate the e icacy of simple ultrasound rules by IOTA group to discriminate between benign and malignant ovarian tumour. The study was a prospective case control study. Patients with adenexal mass were evaluated using simple ultrasound rules by IOTA group and classi ied as benign or malignant. Findings were correlated with histopathological examination of surgical specimen which was considered as gold standard.

Results: Out of 70 patients included in the study IOTA rules were applicable on 65 patients. The sensitivity and speci icity where IOTA rules were applicable was 90.9% and 88.37%.

Conclusion: IOTA simple rules are highly sensitive and speci ic in predicting ovarian malignancy.
