[Sacro-iliac involvement in he course of Paget disease. Report of 6 cases].
OBJECTIVE
Determine the characteristic features of sacroiliac lesions observed in patients with Paget's disease.


METHODS
A retrospective analysis of the hospital files of 87 patients cared for over a period of 12 years was performed. Six patients, 4 women and 2 men, mean age 79 years, were retained for study. In 4 patients one or both sacroiliac joints were involved with complete fusion of the sacral and iliac bones, confirmed by CT-scan in 3. In the 2 other patients, only one border was involved. Scintigraphy showed polyostotic Paget's disease in 3 cases with pelvic localization in the 3 others. Ankylosing spondylarthritis (B27+) was associated in 1 case and in 2 joint chondrocalcinosis without a calcium rim was visualized at the sacroiliac joint. Sacroiliac fusion was related either to new bone forming a bridge in front of the articular space or destruction of the joint cartilage with pagetic fusion.


CONCLUSIONS
Sacroiliac involvement in Paget's disease leads to joint fusion by cartilaginous destruction and should suggest possible ankylosing spondylarthritis, ankylosing vertebral hyperostosis, or joint chondrocalcinosis.
