Immature teratomas (IT) are rare germ cell tumors with malignant behavior, distinct from the benign mature teratomas. Clinical differentiation poses challenges, demanding a comprehensive, multidisciplinary diagnostic approach. This case series delves into the detailed radiological imaging findings of ITs. Pelvic MRI was conducted on five cases with adnexal masses, all of which were histopathologically confirmed as ITs. Radiologically, larger tumor size and scattered fatty components were key diagnostic indicators. This study underlines the importance of comprehensive evaluation in IT diagnosis and management, with MRI as an essential tool in the clinical workflow.
