Where is a Baker's cyst located?

• A. Olecranon process
• B. Greater tubercle
• C. Popliteal fossa
• D. Carpal tunnel

Answer: (C)

A Baker's cyst, also known as a popliteal cyst, is found in the popliteal fossa, which is located at the back of the knee. It is a fluid-filled sac that forms when synovial fluid accumulates in the knee joint, often due to underlying conditions such as arthritis or meniscal tears. When this fluid build-up occurs, it protrudes into the popliteal fossa, leading to the formation of a Baker's cyst. The other locations mentioned in the choices do not pertain to the anatomical site of a Baker's cyst. The olecranon process refers to the bony prominence of the elbow, the greater tubercle is a part of the humerus near the shoulder, and the carpal tunnel is a passageway in the wrist. Therefore, these options are unrelated to the formation of a Baker's cyst, highlighting the specificity of the correct answer concerning its anatomical location.
