Abstract |
Myocardial perfusion imaging with 201T1-chloride
following exercise or vasodilator-induced hyperemia has
been effective in detecting the presence of coronary
artery disease. An increased lung uptake of thallium
has been reported as a sensitive marker of severe and
extensive coronary artery disease and associated with
poor prognosis. Thallium has also been noted to
concentrate in a variety of malignant lesions. We
report 5 cases of extracardiac uptake of thallium
during myocardial perfusion scan with pharmacologic
vasodilation. Accumulation of thallium was found in the
lesions of a breast cancer, a lung cancer, a
Castleman's disease and 2 cases of thymoma. We believe
that the presence of focal extracardiac uptake of
thallium during myocardial perfusion scan should
suggest the need for further clinical evaluation to
detect the tumor and must differentiate the increased
lung uptake of thallium due to left ventricular
dysfunction in coronary artery disease. |
