The imaging findings of pelvis obtained by magnetic resonance imaging. a On axial T1-weighted image, bilateral ovarian cystic tumors showing high intensity. The right ovarian tumor was multilocular (arrow). The left ovarian tumor contained low-signal-intense papillary nodules up to 3.0 cm in diameter (arrowhead). These nodules showed heterogeneous high intensity (arrow) on axial T2-weighted image (b) and high intensity (arrow) on diffusion-weighted image (c) and were enhanced (arrow) on axial gadolinium-enhanced and fat-suppressed T1-weighted image (d). Left pelvic enlarged lymph node with marked enhancement existed nearby the ovarian tumor (arrowhead) (d)
