An echogenic line in the outer zone of the renal medulla, paralleling the corticomedullary junction is described as the renal medullary rim sign. This renal ultrasonographic change is demonstrated in 4 dogs and 2 cats with a range of renal diseases. The renal medullary rim sign provides additional ultrasonographic criteria indicating primary renal disease in some patients. However the renal medullary rim sign may prove to be a poor correlate for prognosis across the range of differentials present in these clinical patients.
