Implication

Radiological review demonstrates distinctive magnetic resonance imaging features of pigmented villonodular synovitis, highlighting the value of MRI for noninvasive joint assessment.

Key Points

Characterize the magnetic resonance (MR) imaging features of pigmented villonodular synovitis (PVNS) to aid in accurate noninvasive diagnosis and surgical planning.
Evaluated radiographic and magnetic resonance imaging findings characteristic of intra-articular pigmented villonodular synovitis.
Analyzed signal intensity patterns across pulse sequences and assessed soft tissue morphology and joint involvement.
Lesions consistently demonstrate low-to-intermediate signal intensity on both T1- and T2-weighted sequences due to magnetic susceptibility effects from hemosiderin accumulation.
MR imaging accurately defines the extent of lobulated synovial proliferation, associated joint effusions, and bone erosion patterns.
