Abstract:
A 62-year-old man with echocardiographic findings suggestive of cardiac amyloidosis and positive 99m Tc-pyrophosphate ( 99m Tc-PYP) scintigraphy was ultimately diagnosed with Fabry disease confirmed by genetic testing. This case highlights myocardial 99m Tc-PYP uptake in Fabry cardiomyopathy, expanding the differential diagnosis of non-amyloid cardiomyopathies associated with myocardial radiotracer retention.
