Dissected popliteal cyst: an unusual presentation of acute gout

Insights

Acute gout and a dissected popliteal cyst can mimic rheumatoid arthritis and thrombophlebitis. This case highlights the importance of considering gout in differential diagnoses presenting with leg swelling and pain.

Area of Science:

  • Rheumatology
  • Vascular Surgery

Background:

  • Gout is a common inflammatory arthritis.
  • Popliteal cysts can dissect, causing pseudothrombophlebitis.

Observation:

  • A 46-year-old man presented with symptoms mimicking rheumatoid arthritis and thrombophlebitis.
  • The patient had acute gout and a dissected popliteal cyst.

Findings:

  • Clinical and laboratory diagnoses confirmed acute gout and a dissected popliteal cyst.
  • The presentation mimicked other serious conditions.

Implications:

  • This case underscores the need for broad differential diagnoses in leg pain and swelling.
  • Accurate diagnosis is crucial to avoid mismanaging gout as thrombophlebitis or arthritis.
