A
localized wedge-shaped osteolytic lesion is often the initial
radiographic feature of Paget's disease. More commonly, osteolytic
foci and sclerotic foci are observed in the same bone. The appearance
of an osteolytic wedge advancing up or down the bone is typical
of the osteolytic phase of Paget's disease in a long bone. In
this x-ray film, a distal osteolytic lesion has progressed proximally
from the region of the knee. The contrast between the resorbed
bone (lower portion) and the radiodense, healthy bone (upper
portion) is notable. |
