case_images: MRI images. (a) T1WI, (b) T2WI, and (c) DWI. The tumor (arrow) showed low intensity in T1WI and high intensity in T2WI.

case_images: Gd-enhanced magnetic resonance imaging showed low intensity on T1-weighted imaging (T1WI) and high intensity on T2WI (Figure 1).
case_images: PET-CT revealed no uptake at the tumor (arrow).

case_images: Positron-emission tomography (PET)-CT showed no uptake in the mass (Figure 2).
case_images: Contrast-enhanced CT. Contrast CT revealed slightly enhancement around the tumor (arrow).

case_images: After starting hemodialysis, enhanced CT suggested hemangioma due to the high degree of enhancement in the tumor at an early phase with an irregular cystic lesion (Figure 3).
case_images: CT images. The tumor developed gradually.

case_images: Due to the tumor's growth and induction of hemodialysis, we decided to perform tumor resection (Figure 4).
case_images: Resected tumor was capsuled (arrow).

case_images: fig5
case_images: If the patient had not already started hemodialysis, adrenalectomy might have been an option (Figures 5 and 6). The resected tumor was solid and dark blown in color, measuring 50 x 37 x 30 mm in size (Figure 5).
case_images: Hematoxylin and eosin staining.

case_images: If the patient had not already started hemodialysis, adrenalectomy might have been an option (Figures 5 and 6). No atypia or mitosis was noted in endothelial cells (Figure 6).
