Case contributed by A.Prof Frank Gaillard


Urinary tract infection and chronic back pain. CT was done to rule out urolithiasis.

Patient Data

Age: 55
Gender: Female


CT IVP demonstrates numerous small calcifications located in the renal calculi which are non-obstructing and measure up to 3mm on the right and 4mm on the left. Urographic phase imaging demonstrates dilated renal tubules in which these non-obstructing calculi are located.

Case Discussion

Overall, the appearances of this case are most in keeping with medullary sponge kidney, a relatively common but often under diagnosed condition.
