MR imaging of acute renal cortical necrosis. A case report.

MR imaging of a patient with acute renal cortical necrosis secondary to massive bleeding following an abortion is presented. The kidneys were enlarged with a high signal intensity observed in the renal cortex on both T1- and T2-weighted images. Follow-up MR imaging showed thinned renal cortex of low signal intensity on both pulse sequences representing renal cortical calcification which was confirmed on conventional radiography and CT.
