Multi-microcystic kidney disease secondary to long-term lithium therapy can be detected with MR imaging regardless of known renal impairment. Preservation of renal CMD was observed in both patients with normal kidney function. The results of our preliminary study suggest the possible role of MR imaging for the screening of early manifestations of nephropathy in patients undergoing chronic lithium therapy.
