Gallium-67 citrate localization in the heart secondary to constrictive pericarditis with myocardial fibrosis

Scintigraphy has demonstrated gallium-67 accumulation within the heart in pericarditis and cardiomyopathies of various kinds. We present a case report of a 63-yr-old man with multisystem disease who showed extensive myocardial uptake of Ga-67 by scintigraphy. At autopsy, constrictive pericarditis with myocardial fibrosis was found. Gallium-67 localization has not been documented previously in myocardial fibrosis accompanying constrictive pericarditis.
