Overview
In our practice, we encountered an atypical scintigraphic finding in a patient who was examined for suspected cardiac amyloidosis.
We were somewhat surprised by the scintigraphic findings after the application of 99mTc-DPD, in which there was a complete lack of radioindicator deposition in the skeleton, significant accumulation was in the lungs, and to a lesser extent in the myocardium. We, therefore, repeated the examination in another week. The finding was identical to that performed a week ago. At the same time, a hematological diagnosis was carried out and everything was finally clarified by the fact that the patient was diagnosed with AL amyloidosis. In the case of suspicion of cardiac amyloidosis, a hematological examination is always performed and all findings must be evaluated.
