Popliteal masses masquerading as popliteal cysts.

Area of Science:

• Orthopedics
• Oncology
• Radiology

Background:

• Popliteal swellings are often diagnosed as synovial cysts, commonly associated with knee arthritis.
• Accurate diagnosis is crucial for effective treatment and patient outcomes.

Observation:

• Two cases presented with popliteal swellings initially misdiagnosed as synovial cysts.
• These swellings were found to be unrelated tumors of significant medical concern.

Findings:

• The misdiagnosis highlights the potential for serious underlying pathology in popliteal swellings.
• Tumors should be suspected in cases with neurological signs or large cysts near noninflamed knee joints.

Implications:

• This emphasizes the need for thorough diagnostic evaluation beyond simple synovial cysts.
• Early and accurate diagnosis of popliteal tumors can lead to better patient prognosis and management strategies.
