A rare, noninfected popliteal synovial cyst containing gas was observed. Plain radiographs effectively identified gas bubbles and calcification, outperforming MRI and ultrasound in this unique case.

Area of Science:

  • Radiology
  • Orthopedics
  • Medical Imaging

Background:

  • Popliteal synovial cysts are typically fluid-filled sacs behind the knee.
  • Infection or gas within these cysts is uncommon.
  • Diagnostic imaging modalities like MRI and ultrasound are standard for evaluation.

Observation:

  • A case of a popliteal synovial cyst containing gas, without infection, is presented.
  • The cyst's atypical appearance included visible gas bubbles and calcification.
  • The exact cause of the gas within the cyst remained undetermined.

Findings:

  • Plain radiographs successfully distinguished gas bubbles and calcification within the cyst.
  • These radiographic findings were not readily apparent on MRI and ultrasound.

  • The study highlights the diagnostic utility of plain radiography in specific cyst presentations.

    • Implications:

    • This case underscores the importance of considering plain radiographs for atypical synovial cysts.
    • Radiographs can offer unique diagnostic value when advanced imaging is inconclusive for gas or calcification.
    • Further research may explore the etiology of gas formation in noninfected synovial cysts.
