Bilateral LGSC associated with SBT and peritoneal metastases in a 33-year-old female. Sagittal and axial T2-weighted MR images (a, b) and axial post-contrast subtraction image (c) display a bilateral biloculated ovarian tumour, with papillary projections (arrows), that probably correspond to SBT component, and significant solid aspects (arrowheads) presumably attributable to LGSC component. Axial b-1000 s/mm² diffusion-weighted image (d) and ADC map (e) show diffusion restriction in solid components. Gross section of surgical specimen of the left tumour (f). The ovary is replaced by a multicystic tumour with solid white nodules, corresponding to areas of LGSC (*). Small papillary projections were occasionally a component of SBT
