UNUSUAL RADIOLOGICAL FEATURES IN PAGETS-DISEASE OF BONE

The radiological diagnosis of Paget's disease of bone is usually strai ghtforward because most cases conform to well-established classic desc riptions. Diagnosis becomes more difficult, however, when radiological appearances are not typical or other disease processes mask or alter the behavior of Paget's disease. Examples are presented to illustrate four categories of unusual radiological presentation of Paget's diseas e: (1) unusual disease progression, (2) massive post-immobilization ly sis, (3) metastatic spread to pagetic bone, and (4) vertebral end-plat e destruction that mimics infection.
