title: Metastatic calcification in the stomach demonstrated by a bone scan in Bence Jones lambda myeloma.
abstract: A 53-year-old male with Bence Jones lambda myeloma developed hypercalcemia and acute renal failure (calcium 14.4 mg/dl, BUN 40 mg/dl, creatinine 3.0 mg/dl) after initial response to chemotherapy. A 99mTc-MDP bone scan revealed unusual isotope accumulation in the left hypochondrium. Extensive calcium deposition was confirmed in the gastric mucosa in the postmortem examination. Detection of gastric calcification by a bone scan is very rare. Only two cases of gastric calcification visualized on bone scans can be found in the literature, one with multiple myeloma) and one in Hodgkin's disease).
