A 60-year-old man complained of cough and swelling and pain of both arms. Chest radiography and CT scans showed atelectasis in the left upper lobe caused by a tumor. Transbronchial lung biopsy was performed, and a histological diagnosis of adenocarcinoma was established. Bone radiography showed subperiosteal new bone formation in the upper extremities. Bone scintigraphy, performed with 99m-Tc-MDP, showed abnormal accumulations in the tubular bones of both arms and patellas, and in the left leg. For months after left upper lobectomy, the clinical, radiological and scintigraphic abnormal findings disappeared. The differential diagnosis pulmonary hypertrophic osteoarthropathy is important. In addition to clinical signs, bone scintigraphy is helpful diagnostically.
