| Explanation | [[Explanation::Paget's disease of the bone (osteitis deformans) is characterized by abnormal bone architecture due to increased bone cellular activity. Paget's disease is associated with increased risk of arteriovenous shunts that cause high-output heart failure. Paget's disease is also associated with osteogenic sarcoma (osteosarcoma), a bone tumor of the young of poor prognosis that usually affects the metaphysis of long bones.
Educational Objective: Paget's disease of the bone is associated with increased risk of high output heart failure due to arteriovenous shunts. |
