Bone scintigram in cardiac amyloidosis: a case report

Area of Science:

• Cardiology
• Nuclear Medicine
• Pathology

Background:

• Amyloidosis can infiltrate the myocardium, leading to severe congestive heart failure.
• Accurate diagnosis of cardiac amyloidosis is crucial for patient management.

Observation:

• Intense, diffuse uptake of Technetium Tc-99m pyrophosphate (Tc-99m-PYP) was observed in the right and left ventricles.
• The patient had biopsy-proven amyloidosis and severe congestive heart failure.

Findings:

• The observed Tc-99m-PYP localization provides strong presumptive evidence of myocardial amyloid infiltration.
• This nuclear imaging finding is particularly significant when amyloidosis is confirmed elsewhere in the body.

Implications:

• Tc-99m-PYP scintigraphy may serve as a valuable non-invasive tool for diagnosing cardiac amyloidosis.
• Early detection through imaging can facilitate timely therapeutic interventions and improve patient outcomes.
