Abstract

Acute renal cortical necrosis (RCN) is a rare condition of partial or complete necrosis of the renal cortex, and this usually spares a thin tissue rim under the capsule and usually a thicker layer adjacent to the corticomedullary junction. We found bilateral RCN, including limited RCN in a hydronephrotic kidney, on three phase multi-detector row CT. This disparity of RCN between the two kidneys is a very rare condition. So here we report the MDCT findings of bilateral RCN, including limited RCN in a hydronephrotic kidney.

  Fig. 1 The CT finding of A 44-year-old woman with serous papillary adenocarcinoma on the left ovary and left hydronephrosis A. The preoperative axial CT scan shows left hydronephrosis by compression. B. The preoperative axial CT scan shows that a multi-septated cystic mass at the left pelvic cavity has displaced the pelvic organs to the right anterior side. C-E. The postoperative axial three-phase CT scan shows decreased parenchymal enhancement in both kidneys. The right kidney exhibits a non-enhancing cortical band with preserved enhancement in the subcapsular, inner cortex and medullary portions. The low density cortical band in the left kidney (black arrows) is delineated in all 3 phases, but it is most prominent in the corticomedullary phase. F. The postoperative coronal image shows decreased parenchymal enhancement in both kidneys. G. A three-month follow-up axial CT scan shows the decreased size and delayed parenchymal enhancement of the right kidney, as compared with that of the left kidney.
