We report a large mobile bladder calculus with intense 99mTc-MDP uptake demonstrated on both whole-body bone scintigraphy and SPECT/CT images in a patient with complicated chronic history of urolithiasis and urinary tract infection. Bone tracer uptake in bladder calculus is a rare phenomenon and might be related to the composition and matrix of calculus, direct exposure to excreted radiotracer, and bacterial colonization on the surface of calculus.
