Ganglion Cysts - Foot
Ganglion cysts arise from the fluid filled areas on the ligaments or between the bones. The cyst is a sac-like structure filled with fluid. The fluid is harmless but can become thicker over time, making the cyst feel firm and spongy. A ganglion cyst can grow large, but it will not spread to other parts of your body.
Ganglion cysts may be painless, but they can cause tingling, burning, numbness, aching, or pain if they are on or near a nerve. The cyst may interfere with wearing shoes or walking.
Sometimes doctors use needle aspiration to confirm the diagnosis of a ganglion cyst. This simple procedure involves numbing the area and then using a syringe and needle to draw fluid from the cyst. The fluid is examined to confirm the diagnosis and rule out any other condition.
In some cases, imaging tests, such as ultrasound or magnetic resonance imaging (MRI) scans, are used to gather more information about the cyst and surrounding structures. Imaging tests are helpful to determine if a growth is fluid-filled or solid. The images may also show if an artery or blood vessel is causing the bump.
Needle aspiration is also used as a treatment for ganglion cysts. After the fluid is removed, the site is injected with steroid medication. Needle aspiration is a fairly successful treatment, although some people may need to have repeated procedures.
Outpatient surgery is recommended if the ganglion cyst is painful, causes numbness or tingling, or interferes with walking or movement. After the area is numbed, the cyst is surgically removed.
