What Is a Cyst?
5. Ganglion Cyst
A ganglion cyst is a cyst filled with fluid and is often associated with a tendon or joint sheath. It is most commonly found at the back or front of the wrist. The ganglion cyst generally develops over several months. Some symptoms of ganglion cysts include pain, numbness, and may result in carpal tunnel syndrome.
The cause of ganglion cyst is still unclear. However, the underlying mechanism is believed to involve an outpouching of the synovial membrane. The risk of a ganglion cyst increases in those who perform sports such as gymnastics. Diagnosis can be achieved via examination by shining a light through the lesion. Medical imaging may be useful to rule out other causes. Treatment of ganglion cysts include observation, splinting, needle aspiration, and surgery.
