There are periostal proliferations along the diaphyses of the radius, ulna and metacarpal bones with adjacent soft tissue swelling. Similar changes were viewed in all other 3 legs.  These findings are compatible with Hypertrohic Osteopathy (HO). This condition may occur secondary to pulmonary masses, and occasionally  to abdominal disease, e.g. hepatic or urinary bladder neoplasia, cystic calculi.
Abdominal radiographs were normal. Thoracic radiographs revealed a mass in the right middle lung lobe. Click here to view these radiographs. FNA revealed pulmonary adenocarcinoma.
