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

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

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).
CT images. The tumor developed gradually.

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

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).

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).
