Ganglion Cyst

Ganglion cysts are fluid-filled, benign (noncancerous) soft tissue tumors. They often occur on top of or under your wrist or at the base of a finger. They appear as a bump or a mass that’s well-defined and not attached to the skin. These cysts are common and only become an issue when symptoms worsen.

Diagnosing Ganglion Cysts

If you think you have a ganglion cyst, see a hand and wrist specialist for a thorough evaluation and to learn about your treatment options.​ A ganglion cyst can mimic other medical conditions, so it’s important to receive an accurate evaluation and diagnosis from a specialist.

Signs & Symptoms

Symptoms of a ganglion cyst can include:

• Aching and/or pain in your wrist or finger
• A cyst or bump that is smooth, firm, round or tender
• Loss of function
• Pain
• Swelling localized to the wrist or finger
• Weakness

Diagnosis

In addition to a review of your health history and a physical exam, your provider may recommend one or more imaging tests to rule out other conditions:

• Magnetic resonance imaging (MRI)—to create images of your soft tissues and bone.
• Ultrasound—a safe, painless test that produces pictures using sound waves.
• X-rays—to create images of your bones and soft tissue.

Treatments for Ganglion Cyst

Treatment for ganglion cysts is often unnecessary if the cyst is small and painless. However, if the cyst grows and begins to interfere with hand function, it is time to discuss treatment with an orthopedic expert.

Nonsurgical Treatments

The nonsurgical treatments we offer for ganglion cysts include:

• Anti-inflammatory medications (NSAIDs)—to reduce pain.
• Aspiration—draining your cyst using a small needle.
• Cortisone injections—to reduce swelling and inflammation.
• Rest—limited activity gives your body time to heal.
• Splints—to immobilize your hand or wrist.

Surgical Treatments

We may recommend surgery to remove your ganglion cyst if your symptoms are severe.
