title: Displaced calcium as a sign of transitional cell carcinoma in analgesic nephropathy.
abstract: Transitional cell carcinoma is associated with analgesic nephropathy. Detection of this neoplasm may be delayed because hematuria and colic are the usual symptoms in both conditions. Plain film findings of displacement of the renal calcifications occurring in analgesic nephropathy may be the first sign of transitional cell carcinoma.
