Case contributed by Henry Knipe
Diagnosis certain

Presentation

Left flank pain. Follow-up x-ray.

Patient Data

Age: 60 years
Gender: Male

Left paraspinal calcification adjacent to the L3 inferior endplate in keeping with a ureteric calculus.

Dilated left ureter and pelvicalyceal system with retained iodinated contrast.

Small left lower renal calculus.

Case Discussion

A portal venous phase CT abdomen was performed the day prior as the patient's initial presentation was non-specific. This demonstrated a left ureteric calculus, left renal calculus and mild left hydronephrosis, which is still visible on this x-ray due to retained contrast.
