Abstract
A 57-year-old woman who had persistent symptoms of transthyretin cardiac amyloidosis underwent 99mTc-pyrophosphate (99mTc-PYP) scintigraphy. The 99mTc-PYP planar and SPECT/CT fusion image showed diffuse myocardial uptake and multiple fractures of the sternum and ribs. These fractures interfered with semiquantitative scores of 99mTc-PYP uptake, leading to false positive in 99mTc-PYP imaging.
