Paget's disease is disorder of bone remodeling which is focal (located in discrete areas in the bones and not throughout the entire skeleton). The abnormal remodeling results in overgrowth or deformity of bone. Paget's disease usually occurs in adults who are older than 55 years old, and there are slightly...

Paget’s disease, or osteitis deformans, is a common condition in the middle-aged and elder persons. The disease is present in approximately 10% of patients over the age of 80 years. It is more common in men than in women. Seventy-percent of Paget’s disease is discovered as an incidental finding, patients...

ACR-code 338-84 Four cases of patients in late middle age with back pain.
The first image shows increased density in the vertebra with loss of fine detail and a coarse zone of increased density making a thickened rim around the vertebra, a 'picture frame' vertebra. The CT cuts show irregular variation...

Radiology case 438-843: Paget's Disease Clinical presentation: Mature adult male with painful hands.
There is increased density of the proximal phalanx of the left middle finger, the left 2nd metacarpal and the base of the right 5th metacarpal. The bones no longer show the pattern of cortex and medulla that can be...

Paget's Disease of the Skull: Radiology teaching file
Multiple hazy, sclerotic areas seen in calvarium. This is the typical "cotton wool" appearance of the sclerotic phase of Paget's Disease in the skull.

Radiology case 468-842: Paget's Disease Tibia Clinical presentation: Pain and deformity in the leg of an elderly man.
There is antero-posterior bowing of the tibia. The process involves grossly disordered architecture with loss of the usual cortico-medullary distinction. The process extends to the knee joint and the bone is larger and more...

Paget's disease is a disease of bone, which develops disordered architecture and is found more commonly in the elderly and in males. The mechanism for this pathology is unknown. Under the microscope, the disease shows disorder of the basic structural unit, normally an arrangement of concentric Haversian Systems. Radiographically, this...

Sarcoma complicating Paget's disease of bone. A clinicopathological study of 62 cases.Schajowicz F, Santini Araujo E, Berenstein M. Out of 21 900 cases filed at the Latin-American Registry of Bone Pathology between April 1940 and July 1981, there were 987 with Paget's disease (4.51 per...

Paget’s disease (PD) is a chronic metabolically active bone disease, characterized by a disturbance in bone modelling and remodelling due to an increase in osteoblastic and osteoclastic activity. The vertebra is the second most commonly affected site. This article reviews the various spinal pathomechanisms and osseous dynamics involved in producing...
