Ovarian masses are most commonly observed in adults; they rarely occur in children. The majority of the ovarian masses encountered in children or patients of pre- menarchal age are non-neoplastic lesions. The clinical signs and symptoms of ovarian masses are usually non-specific. Early management may be necessary to preserve fertility. Gynecological malignant conditions constitute approximately 3% of all types of cancer in children. Ovarian tumors in children account for only 1% of childhood malignancies. However, the true incidence of malignant ovarian tumors in the pediatric population is unknown. is to study the role of magenetic resonace (MR) imaging in evaluation of neoplastic and non-neoplastic masses arising from uterine adnexa in neonates and pediatric age groups. During a period of 12 months (from December 2017 to December 2018), 100 consecutive patients (age range, 1–14 years; mean age, 8.8 years) with different clinical presentations were enrolled in this study. There was a highly significant reduction in the overall sexual satisfaction after hysterectomy (p < 0.001). On the basis of the findings, the study concludes that MRI is good modality for differentiation of benign and malignant adnexal masses. Certain imaging features and the degree of enhancement on MRI images are helpful in differentiating adnexal masses. Thus, imaging findings may contribute incremental value to clinical parameters in providing prognostic information, consequently improving the quality of the data used in therapeutic planning
