Abstract:
A patient with strikingly reduced Tl-201 myocardial retention after intramuscular administration of gold therapy (sodium aurothiomalate) is described. Following a routine Bruce protocol exercise test, postexercise scintigraphy was normal; an abnormal scan of the thorax was obtained on delayed imaging at 3 hours. This scan showed no demonstrable myocardial retention of tracer. In between the two acquisitions, the patient received 50 mg intramuscular sodium aurothiomalate for rheumatoid arthritis. A repeat scan obtained 3 days later showed a normal myocardial scintigram. It is recommended that patients receiving intramuscular gold therapy should not undergo such treatment close to the timing of Tl-201 myocardial scans.
