case_images: CT scan revealed a 58 x 43-mm retroperitoneal cystic mass with solid components that were indistinguishable from the psoas major and left kidney. Contrast-enhanced CT showed delayed enhancement of solid components and no enhancement of cystic components ( Figure 2A ). The final pathology result was clear cell adenocarcinoma ( Figure 2B ). Figures 2C-F ). Finally, PRMA was confirmed.
