Ganglion
GANGLION CYST
A benign mass or swelling overlying a joint or tendon that commonly appears on your wrist or finger joints
About a ganglion
The clinical presentation of a ganglion is a visible bump. The exact cause of a ganglion is unknown but ultimately, a ganglion is a fluid-filled sac that arises from a tendon or joint that may be irritated.
Need to know
Although ganglion's are often symptom-free, they can become painful with certain activities, movements or positions. This can interfere with everyday functions and typically come and go. Ganglion's can also press against a nerve, causing pins and needles, numbness or generalised discomfort. Aside from serious medical consequences, you might simply be unhappy due to the general appearance of the bump.
The diagnosis of a ganglion is typically straightforward. Our hand specialists are able to quickly diagnose and recommend the most appropriate form of treatment.
Non-invasive treatment options may include:
- rest and/or splinting, limiting movement and load through the joint to reduce irritation to the ganglion
- aspiration, draining of the fluid-filled sac using a needle; sometimes a steroid injection is recommended
Surgical removal of a ganglion may be suitable when the lump is persistent and causing other issues.
