Abstract

Renal hemangioma is an uncommon benign tumor which usually causes painless or painful gross hematuria. Its preoperative diagnosis is extremely difficult or even impossible. We experienced three cases of renal hemangioma, located mainly at the pelvocalyceal junction or in the inner medulla. US demonstrated variable echogenecity, and CT revealed a lack of significant enhancement. Where there is gross hematuria in a young adult, especially when the renal mass located in the pelvocalyceal junction or inner medulla shows little enhancement on CT, renal heman-gioma should form part of the differential diagnosis.

  Fig. 1 Renal hemangioma in a 31-years-old man. Longitudinal US shows a well-defined round echogenic mass lesion (arrows) containing multiple anechoic areas in the lower pole of the right kidney.

• 

  Fig. 2 Renal hemangima in a 31-years-old man. A. US shows a 1.5 cm-sized mass (arrow) in the pelvis of the left kidney, which is isoechoic to renal parenchyma. B. Enhanced CT scan shows a non-enhancing, low attenuated mass with lobulated margin (arrows) adjacent to the pelvis.

• 

  Fig. 3 Renal hemangioma in a 31-years-old man. A. Enhanced CT scan shows a non-enhancing mass with lobulated margin in the lower pole of the left kidney. Unenhanced CT scan shows a high-attenuated mass suggesting hemorrhage (not shown). B. Gross pathologic specimen shows a hemorrhagic lesion (arrows) at the corticomedullary junction of the lower pole.
