What does a Ganglion Cyst mean?
A ganglion cyst is a benign cystic mass, which oftentimes presents in the wrist or hand. The mass usually presents as small “pea-sized” but usually enlarges over time. The mass is cystic, in that it contains joint fluid, which is trapped outside the joint through a one way valve mechanism. The cystic mass contains joint fluid, which is trapped outside the joint space through a one-way valve effect which allows the fluid to come out of the joint space, but is prevented from flowing back.
Ganglion cysts most commonly develop along the tendons or joints of the wrist or hand. Patients may also notice the fluid vary in size. Based on the position of the cyst, pain may result if the mass presses against a nearby nerve. Additionally, some people may experience tingling, numbness, and stiffness.
The fluid can sometimes be removed with a needle, but oftentimes this treatment is only temporary as the cyst usually reoccurs. The best way to make sure the cyst does not reoccur is to have it surgically removed.
