Abstract

We report a case of renal hemangiopericytoma occurring in renal sinus and expanding to the renal hilum. This unusual presentation caused misinterpretation of this tumor as transitional cell carcinoma of the renal pelvis clinically. The patient who was a 30-year-old woman had a relatively well demarcated solid tumor, 8 x 6 cm, in the renal sinus of the left kidney.
