Scintigraphic findings in primary amyloidosis of the heart and stomach.
The effectiveness of scintigraphic studies in the study of patients with primary systemic amyloidosis has not been reported previously. This case report describes a patient with the scintigraphic findings of thickened myocardium and delayed gastric emptying, which correlated well with the presence of amyloid deposits in these organs at autopsy. Additionally, the liver and spleen had normal scintigraphic appearances and were free of amyloid at autopsy. Radionuclide studies appear useful in assessing the anatomic and physiologic abnormalities assessed by amyloid deposition.
