What is a ganglion?

• A. A nerve entrapment in the wrist
• B. An infection of a joint
• C. A sac-like swelling or cyst formed from the tissue that lines a joint or tendon
• D. A bone spur near a joint

Answer: (C)

A ganglion is a sac-like swelling or cyst formed from the tissue that lines a joint or tendon. It typically appears as a soft lump near a joint, often on the wrist, and contains gel-like fluid. It’s not an infection, not a bone spur, and not nerve entrapment. Nerve entrapment involves pressure on a nerve, an infection would cause joint inflammation with possible fever and redness, and a bone spur is a bony growth from the bone itself. The key idea is that a ganglion arises from the synovial lining or tendon sheath and presents as a cystic structure.
