Pelvic magnetic resonance (MR) images of a 62-year-old man with bladder cancer (stage pT2b). a Transverse T1-weighted MR image shows a hyperintense lymph node with round shape and a short-axis diameter of about 6.0 mm in the left perivesical region. The fatty hilum shows high signal intensity on the image (yellow arrows). b In out-of-phase MR imaging, the fat signal was suppressed in the lymph node (yellow arrows). This lymph node with fatty hilum was proved to be benign in pathologic diagnosis
