The lesion showed a hypoechoic mass with abundant blood flow signals in the perirenal space on US (A). Axial CT of the abdomen (plain scan and venous phase) showing a slightly low-density lesion (B) in the retroperitoneal space that was well-defined and with obvious enhancement (C). Axial pancreatic MRI showing a solid lesion with several cystic lesions, T1WI showed hypointensity (D), T2WI showed high-intensity (E), and DWI showed iso-intensity (F). The lesion had obvious progressive enhancement (G–I)
