Abstract
A 57-year-old woman who had persistent symptoms of transthyretin cardiac amyloidosis underwent 99m Tc-pyrophosphate ( 99m Tc-PYP) scintigraphy. The 99m Tc-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 99m Tc-PYP uptake, leading to false positive in 99m Tc-PYP imaging.
