Case Report


A 71-year-old man with rheumatoid arthritis complained of pain and swelling in the left calf. X-ray examination of the calf disclosed radiolucencies suggestive of soft tissue gas; however, subsequent investigation revealed no evidence of infection and an arthrogram showed a dissected popliteal cyst in the area of the gas. Gas-like radiolucencies in a popliteal cyst are an unusual finding which has not been previously reported.
