The purpose of this exhibit is: 1. To highlight the role of MRI in the characterization of ultrasound indeterminate adnexal lesions. 2. To review the imaging findings of the different pathological entities that present with low signal on T2- weighted sequences. 3. To emphasise the need of an adequate MR protocol to clarify the origin of the lesions. 4. To explain the potential role of diffusion-weighted imaging (DWI) in the correct identification of misclassified lesions based only on the T2 signal intensity within the solid component.

• Technical aspects of MR imaging protocol for low-T2 signal adnexal lesions characterization. • Imaging and pathological features of the lesions presenting with low-T2 signal of solid component. • Possible DWI presentations of both benign and malign low-T2 lesions.
