A ganglion cyst is a sac filled with a jellylike fluid that originates from a tendon sheath or joint capsule. The word “ganglion” means knot and is used to describe a knot-like mass or lump that forms below the surface of the skin.
Ganglion cysts are among the most common benign soft-tissue masses. Although they most often occur on the wrist, they also frequently develop on the foot—usually on the top. Ganglion cysts vary in size, may get smaller and larger, and may even disappear completely. Ganglion cysts can be unpredictable and difficult to get rid of.
Although the exact cause of ganglion cysts is unknown, they may arise from trauma—whether a single event or repetitive microtrauma.

Your doctor may take an x-ray, and in some cases, additional imaging studies may be ordered.
There are various options for treating a ganglion cyst on the foot:
When other treatment options fail or are not appropriate, the cyst may need to be surgically removed. While the recurrence rate associated with surgery is much lower than that experienced with aspiration and injection therapy, there are nevertheless cases in which the ganglion cyst returns.
