Figure 4.
A post-menopausal nulliparous 45-year-old female with right ovarian squamous cell carcinoma arising on the top of immature cystic teratoma. (a) Sagittal T2 weighted fast spin echo shows large adnexal complex mass with rounded matted tuft of hair seen centred on fluid sedimentation levelling (black star). Associate mural-based lobulated soft-tissue component (white arrow). (b) A collective figure included in the upper row from left to right: sagittal post-contrast T1 high-resolution isotropic volumetric examination (source) image, subtraction post-contrast image (best distinction of the enhancing soft tissue seen adherent to the posterior wall) and colour-coded image. The lower row represented the kinetic analysis of early initial peak of contrast uptake at 78 s with corresponding maximum relative enhancement percentage of 112% and Type III malignant curve pattern. The last image in the lower row represented a colour mapping image (rapid and strongly enhancing areas are displayed in red or yellow, while areas of slow or weak enhancement appear green). U, uterus; UB, urinary bladder. For colour image see online.
