case_images: FIG3
case_images: The lesion had demonstrated low signal intensity on T1-weighted imaging and high signal intensity on T2-weighted and enhanced MRI (Figure 3).
case_images: Histopathological photo of an incisional biopsy. The biopsy confirmed that the lesion originated from renal cell carcinoma (magnification: x100; hematoxylin and eosin stain)
