Summary
Para-articular cysts, fluid-filled sacs near joints, are common findings on imaging. This review details their causes, symptoms, and appearances across various joints and imaging modalities like MRI and CT scans.
Area of Science:
- Radiology
- Orthopedics
- Medical Imaging
Background:
- Para-articular cysts are frequently encountered during routine imaging.
- These cysts can be asymptomatic or present with symptoms like pain, swelling, and joint dysfunction.
- They are often linked to underlying joint pathologies, including trauma, degeneration, and inflammation.
Purpose of the Study:
- To discuss the etiology, clinical manifestations, and imaging characteristics of para-articular cysts.
- To provide a comprehensive overview of para-articular cysts across multiple joint locations and imaging techniques.
Main Methods:
- Review of imaging findings for para-articular cysts.
- Discussion of associated joint disorders.
- Focus on imaging modalities such as arthrography, ultrasound, computed tomography (CT), and magnetic resonance (MR) imaging.
Main Results:
- Para-articular cysts exhibit diverse appearances on imaging.
- Imaging findings correlate with underlying joint conditions.
- Specific attention is given to cysts around the hip, knee, ankle, foot, shoulder, elbow, wrist, hand, spine, temporomandibular joints, and periosteum.
Conclusions:
- Understanding the imaging features of para-articular cysts is crucial for diagnosis.
- Para-articular cysts are important indicators of underlying joint pathology.
- Comprehensive evaluation across various imaging modalities aids in accurate characterization and management.
