Myocardial Uptake of 99m-Tc-DPD in a Patient with Prostate Carcinoma

摘要

We report a 77 year old patient with prostate carcinoma showing benign myocardial uptake of 99m-Tc-DPD in routine bone scintigraphy. Complementary diagnostic examinations were performed showing no incidence of systemic heart disease (amyloidosis, hypercalcimia). No previous chemotherapy or cardioversion were performed. Consequently we conclude, the myocardial uptake was secondary to the prostate carcinoma. Case-Report A 77-year-old male patient was admitted to Nuclear Medicine for staging of a prostate carcinoma prior to surgery. Planar whole body bone scintigraphy was performed on a Genesys gamma-camara (Single Head, ADAC) 3 h after i.v. administration of 670 MBq of 99m-Tc-DPD showing no evidence of bone metastasis but an intensive myocardial tracer-uptake (Figure 1). Consecutive Single Photon Emission Computed Tomography (SPECT) imaging of thorax was aquired demonstrating homogeneous tracer-uptake of the left ventricle (Figure 2).
