Sertoli-Leydig cell tumour in a 13-year-old woman. (a) Sagittal and (b) axial T2-weighted images show a voluminous mixed cystic and solid mass (white arrows). At the periphery of the mass, some signal flow-voids that represent vascular structures are recognizable (white arrowheads). (c) An Axial T1-weighted image shows haemorrhagic areas with high signal intensity within the lesion (white arrow). (d) Axial contrast-enhanced fat-suppressed T1-weighted image shows enhancement of the solid component, more evident in the peripheral portion (white arrow). (e) Photograph of the operating field shows the mass with vascular structures on its surface (white arrowheads). (f) Photograph of the cut surface of the resected lesion shows good MR imaging-histopathologic correlation of the mass
