Summary
Early recognition of diffuse pigmented villonodular synovitis (PVS) is possible with careful MRI review, especially when suprapatellar effusions are present. Arthroscopic subtotal synovectomy offers successful treatment for this condition.
Area of Science:
- Orthopedic Surgery
- Radiology
- Pathology
Background:
- Pigmented villonodular synovitis (PVS) is a rare condition affecting the synovium.
- Diagnosis can be challenging due to varied presentations and overlapping symptoms with other joint pathologies.
Observation:
- The patient presented with suprapatellar effusion and disproportionate swelling, indicative of PVS.
- Initial MRI revealed characteristic PVS findings: synovial thickening and enhancement.
- Asymptomatic return to sport and trauma association initially obscured the diagnosis.
Findings:
- Diffuse PVS can exhibit specific signs on initial MRI, including synovial thickening and enhancement.
- Suprapatellar effusions are a key indicator for careful MRI examination in suspected PVS cases.
- MRI is crucial for early and accurate diagnosis of diffuse PVS.
Implications:
- Early MRI detection of diffuse PVS can prevent diagnostic delays and improve patient outcomes.
- Prompt diagnosis facilitates timely and effective treatment, such as arthroscopic subtotal synovectomy.
- Understanding MRI characteristics aids clinicians in recognizing PVS, even with atypical presentations.
