title: Fat-filled postoperative renal cortical defects: sonographic and CT appearance.
abstract: Surgical filling of renal cortical wedge resection defects with vascularized retroperitoneal fat resulted in postoperative sonographic and CT appearances that simulated focal renal masses in four patients. Correct identification of this abnormality is important in order to avoid unnecessary further evaluation to exclude renal neoplasm.
