A 55-year-old female presented with right ovarian borderline serous cystadenoma. (a) Sagittal T2 weighted fast spin echo shows large complex cystic, mass (M; curved arrows) with septations and posterior wall-based cauliflower soft tissue (straight arrow). Note the vaginal prolapse and intussusception of the cervix. (b) A collective figure: the left column represents sagittal post-contrast T1 high-resolution isotropic volumetric examination image and the colour mapping images (that could detect the most vascular portion of the tumour). The right column represents the kinetic analysis of delayed initial peak of contrast uptake at 288 s with corresponding maximum relative enhancement percentage of 87% and Type I (benign) curve pattern. The morphological features were in favour of invasive malignancy, yet the post-contrast dynamic parameters were more towards benign kinetics. The latter finding was explained by the tumour pathology being a borderline tumour. R, rectum; U, uterus; UB, urinary bladder.
