Diagnostic Value of Magnetic Resonance Imaging in Prediction of Malignancy in Adnexal Masses

Part of the ovary or an adnexal mass that is detected during ultrasound which is inconsistent with normal physiology can be defined as adnexal lesion (1). Adnexal masses may present themselves with many symptoms. These lesions are important in respect to malignant potential. Among gynecological cancers ovarian cancers are the leading cause of mortality. Every one woman in 95 has the risk of ovarian cancer in life time. Unfortunately majority of the patients with ovarian cancer are diagnosed in stage III or IV and 5 years survival rate decreases from 90% (in women cancer confined to ovary Stage I) to 3073% by this stage shift (2). For this reason malignant potential of the adnexal masses are very important. Adnexal masses can be incidentally diagnosed; a woman has a life time risk of undergoing surgery for an incidentally diagnosed adnexal mass is 5-10 %. The incidentally diagnosed adnexal masses are challenging because of difficulty in differentiating whether it is malignant or benign (3,4). Ultrasound is generally used for detection of suspicious adnexal lesions during physical examination or adnexal lesions are diagnosed during an ultrasound performed for another reason. In diagnosis of malignancy MRI has a sensitivity and specificity of 100% and 94% respectively. MRI provides a confident diagnosis of adnexal lesions in benign nature (5,6).
