Bilateral LGSC with SBT and peritoneal metastases in a 25-year-old female. Ultrasound images (a, d) reveal a complex mixed tumour with a multinodular aspect involving adnexal structures (arrow). There is fallopian tubes' dilatation with solid echogenic vegetations inside (arrowheads). Sagittal and axial T2-weighted MR images (b, c) demonstrate a bilateral adnexal mixed tumour, with an arborescent growing on the surface of both ovaries (arrows) associated with severe ascites. Axial b-1000 s/mm² diffusion-weighted image (e) and ADC map (f) show diffusion restriction in a perihepatic peritoneal metastasis (arrows)
