What is synoval cyst of finger?

A synovial cyst of the finger, also known as a ganglion cyst, is a fluid-filled sac that forms near a joint or tendon sheath, typically due to the degeneration of joint tissue or injury. These cysts are usually benign and can vary in size, often appearing as a noticeable lump on the finger or hand. While they may cause discomfort or restrict movement, many synovial cysts are asymptomatic and may not require treatment unless they cause significant issues. Treatment options include observation, aspiration, or surgical removal if necessary.
