Background: Adnexal masses present a special diagnostic challenge in differentiating between benign and malignant lesions. Determination of malignancy is vital and is based largely on imaging appearances. However, ultrasonography(US), Colour Doppler (CD) and Magnetic Resonance Imaging (MRI) are the modalities available which carry no radiation risk and yet valuable in reaching a definitive diagnosis. Settings and design: Twenty six female patients suspected clinically to have adnexal mass or detected to have adnexal mass either on US or on MRI were included in this study. All these cases were imaged with US with CD & MRI. The final diagnosis was determined by histopathology or definitive imaging and/or clinical diagnosis. A total of 30 masses were detected. Results: 28 Out of 30 masses were detected on US. 30 masses were detected on MRI. Definitive diagnosis on US could be obtained in 60% lesions. CD added to the definitive diagnosis of 2 masses. The definitive diagnosis on MRI could be obtained in 25 masses. Conclusion: Our findings support the possibility that Ovarian masses constituted most of the masses, followed by tubal masses and uterine masses (3.33%) of which 93.33% masses could be detected on US. CD did not add further information in detection of masses. All the adnexal masses detected clinically/on US were detected on MRI.
