Figure 1 Magnetic resonance imaging of the abdomen. A: The T2-weighted coronal image shows three distinct oval masses in the left retroperitoneum (indicated by orange arrows), exhibiting a high signal intensity and a well-enhanced pattern; B: The image on the left displays diffusion-weighted transverse images of three retroperitoneal masses (indicated by orange arrows), while the image on the right shows the corresponding gross features of three specimens. The diffusion-weighted transverse images reveal mild restricted diffusion.
