Summary
Magnetic resonance (MR) and CT imaging revealed cystic lesions in hemodialysis patients, suggesting an articular origin distinct from synovial diseases. These findings highlight a probable multifactorial pathogenesis for these bone lesions.
Area of Science:
- Radiology
- Orthopedics
- Nephrology
Background:
- Long-term hemodialysis patients often develop bone lesions.
- The exact origin and pathogenesis of these cystic radiolucencies remain unclear.
Purpose of the Study:
- To characterize cystic radiolucencies in hemodialysis patients using advanced imaging techniques.
- To investigate the relationship between these lesions and joint spaces, and synovial involvement.
Main Methods:
- Ten long-term hemodialysis patients underwent magnetic resonance (MR) and computed tomography (CT) imaging.
- Imaging focused on wrists, shoulders, and hips to identify and characterize cystic lesions.
- MR imaging analyzed lesion content using T1- and T2-weighted sequences.
Main Results:
- MR and CT identified more numerous and smaller lesions than plain films.
- All lesions demonstrated communication with the joint space.
- Synovial hypertrophy was minimal, even with significant osseous erosions.
- MR analysis of wrist lesion content showed variable signal intensities.
Conclusions:
- The findings suggest an articular origin for these lesions, differing from synovial processes like rheumatoid arthritis.
- The pathogenesis is likely multifactorial.
- Transplanted and non-transplanted patient patterns were indistinguishable.
