Paget's disease of bone.

Area of Science:

• Orthopedics
• Radiology
• Bone Metabolism

Background:

• Paget's disease of bone is a common skeletal disorder, typically affecting individuals over 50.
• Its exact cause is unknown, and recent trends show a decrease in its prevalence, severity, and extent.
• Radiological imaging is crucial for diagnosis and monitoring.

Purpose of the Study:

• To review the current radiological investigations for Paget's disease of bone.
• To highlight the evolving role of advanced imaging techniques like CT and MR.
• To discuss potential diagnostic pitfalls and management considerations.

Main Methods:

• Review of current literature and radiological practices for Paget's disease.
• Analysis of the utility of bone scans, radiographs, CT, and MR imaging.
• Discussion of imaging findings in typical and atypical cases, including complications.

Main Results:

• Traditional methods like bone scans and radiographs remain primary diagnostic tools.
• CT and MR imaging are increasingly used for complex or incidental cases.
• Paget's disease can artifactually elevate bone density measurements, potentially masking osteoporosis and increasing fracture risk.

Conclusions:

• Radiological assessment is key to diagnosing and evaluating Paget's disease.
• Awareness of advanced imaging findings and potential pitfalls is essential for accurate patient management.
• Recognizing Paget's disease on incidental imaging avoids unnecessary further investigations.
