Abstract

Hemangioma in the renal pelvis is a very rare benign tumor that may be mistaken for renal cell carcinoma. We present, herein, a case of a 59-year-old woman with a renal mass that was diagnosed as a cavernous hemangioma in the renal pelvis. The patient underwent intravenous pyelography, urine cytology, retrograde pyelography, kidney dynamic computed tomography (CT), and surgical excision.

• 

  Fig. 1 Intravenous pyelography (IVP) shows a filling defect in the middle calyx of the left kidney.

• 

  Fig. 2 Retrograde pyelography (RGB) shows a filling defect in the middle calyx of the left kidney.

• 

  Fig. 3 (A) Axial kidney dynamic computed tomography (CT) images show a poorly enhanced mass-like lesion in the upper calyx of the left kidney (arrow). (B) Coronal kidney dynamic CT images show a poorly enhanced masslike lesion in the upper calyx of the left kidney (arrow).

  Fig. 4 (A) The macroscopic finding shows a 3.5x4.5 cm hemorrhagic, sponge-like round mass in the pole of the left kidney. (B) The microscopic finding shows dilated blood-filled vessels (H&E satin, x100). (C) The microscopic finding shows dilated blood-filled vessels (H&E satin, x100).
