MRI examination of the pelvic cavity. Sagittal T1-weighted image (a) shows a well-defined lobulated mass with isointense and slight hypointense in the pelvic retroperitoneum. The lower part of the mass shows some areas with hyperintense (arrow). Sagittal T2-weighted image (b) and T2-weighted image with fat saturation (c) show the mass with inhomogeneous isointense and hyperintense. Cystic degeneration could be detected in the inner part (arrowhead). The lower part of the mass showed some areas with hypointense (arrow). Coronal T2-weighted image (d) shows large vessels with flow-void sign (arrowhead). Post-contrast T1-weighted images (e-f) show the mass with intense heterogeneous enhancement. The lower part with hyperintense on T1-weighted image and hypointense on T2-weighted image shows no significant enhancement (arrow)
