A fluid-filled lump near a joint, often on the wrist or hand, is known as which?

• A. Ganglion cyst
• B. Bursitis
• C. Osteophyte
• D. Hematoma

Answer: (A)

A ganglion cyst is a fluid-filled swelling that develops from the tissue around a joint or tendon sheath, most commonly around the wrist or back of the hand. It contains a viscous, jelly-like fluid produced by the joint lining and often presents as a soft, rounded lump that may change size with activity. It can be painless but may cause discomfort or restrict movement if it presses on a nerve or tendon. This distinguishes it from options like bursitis, which is inflammation of a bursa and not a cyst filled with joint fluid; an osteophyte, which is a hard bone spur; and a hematoma, which is a bruise-like collection of blood after trauma.
