Pigmented villonodular synovitis (PVNS) is a rare joint condition. This review covers the diverse imaging features of PVNS to aid diagnosis.

Area of Science:

  • Orthopedics
  • Radiology
  • Pathology

Background:

  • Pigmented villonodular synovitis (PVNS) is a rare, benign neoplastic proliferation of the synovium.
  • Its etiology remains largely unknown, contributing to varied clinical and imaging presentations.

Purpose of the Study:

  • To provide a comprehensive overview of the imaging characteristics of PVNS.
  • To familiarize readers with the spectrum of findings across various imaging modalities.

Main Methods:

  • Review of existing literature and case studies.
  • Analysis of imaging findings from multiple modalities including MRI, CT, ultrasound, and radiography.

Main Results:

  • PVNS demonstrates a wide range of appearances on imaging.

  • Key imaging features include synovial thickening, hemosiderin deposition, and characteristic signal intensities on MRI.

    • Conclusions:

    • Accurate interpretation of imaging findings is crucial for diagnosing PVNS.
    • Familiarity with the diverse imaging spectrum aids in differentiating PVNS from other intra-articular pathologies.
