Preoperative scintigraphic evaluation of the location of juxtaglomerular cell tumor.

Juxtaglomerular cell tumor is a rare condition which cannot be correctly diagnosed preoperatively. In the only previously reported case in which scintigraphy has been used, this method failed to detect the tumor. We present a case of juxtaglomerular cell tumor in which renal scintigraphy revealed a well-defined cold area in the hilar region of the left kidney.
