Subepithelial hematoma of the renal pelvicalyceal system simulating renal cystic tumor

ABSTRACT

Only 13 cases of subepithelial hematoma of the renal pelvicalyceal system have been reported. We report the fourteenth case. In 11 of the 13 reported cases, nephrectomy of the involved kidney was performed. Our case is the third case in which only partial nephrectomy was done in this benign lesion. A 38 year old male was referred due to hematuria and left flank pain. Intravenous pyelogram revealed a mass in the lower pole of the left kidney. Ultrasound and CT scanning revealed a cystic mass in the same area. Partial left lower pole nephrectomy was done. Pathology report was benign Anthopol Goldman lesion [subepithelial hematoma of renal pelvicalyceal system]
