Findings: RADIOPHARMACEUTICAL: 13.0 mCi Tc-99m MDP i.v. There are multiple foci of radiotracer uptake predominately involving the appendicular skeleton (Figures 3 and 4). Specifically, there are foci of intense radiotracer uptake within the right first proximal phalanx extending into the first metatarsal head, distal left second metatarsal, right calcaneus, distal right tibia, distal left tibia, right elbow involving the distal humerus and olecranon, posterolateral left seventh rib, manubrium, right coracoid process, base of the right fourth proximal phalanx and in the left third metacarpal head. The CXR preformed three months prior shows an opacity within the left upper lobe (Figure 1) that is persistent three months later (Figure 2). Corresponding X-rays show predominately lytic lesions in the areas of abnormal radiotracer uptake (Figures 5-7). |
