Identification of Bladder Diverticular Stone on 99mTc-Methyl Diphosphonate Bone Scintigraphy and SPECT/CT

Abstract

We report a bladder diverticular stone with increased 99mTc-methyl diphosphonate uptake on bone scintigraphy and SPECT/CT. Diverticular stone is a known risk factor for bladder malignancy. The deposition of 99mTc-methyl diphosphonate on the crystal surface of the diverticular stone is a rare phenomenon but of clinical significance. Cystolitholapaxy is indicated to remove the diverticular stone and to reduce the risk of bladder cancer.

Keywords: 99mTc-MDP; SPECT/CT; bone scintigraphy; diverticular stone.
