title: Multiple ectopic calcification in subcutaneous tissues detected by bone scintigraphy in a patient with chronic renal failure.
abstract: A 56-year-old man presented with swelling bilateral shoulders for 2 months. Plain radiograph and CT demonstrated symmetric masses with plaque calcification in bilateral shoulders. A Tc-MDP bone scintigraphy revealed intense radiotracer uptake not only in the masses of bilateral shoulders but also in the masses of the right buttock and the left thigh. The masses in bilateral shoulders were resected, and the pathological examination confirmed the ectopic calcification. This is a rare case of multiple ectopic calcification in subcutaneous tissues in a patient with chronic renal failure.
