Ganglion Cyst

Definition
A ganglion cyst is a fluid-filled growth that is usually attached to either a tendon or a joint. Ganglion cysts usually appear on the back of the wrist, although they may be on the underside of the wrist, the hand, the fingers, or the feet. Ganglion cysts are always benign.

Causes
The cause of ganglions cysts is unknown.

Risk Factors
A risk factor is something that increases your chance of getting a disease or condition.

• Sex: Female
• Age: 20-50 years old
• Gymnastics

Symptoms
Symptoms include:

• Appearance of a soft bump, usually on the back of the wrist
• May be slightly painful or tender

Diagnosis
The doctor will ask about your symptoms and medical history, and perform a physical exam. Most ganglion cysts are easily diagnosed based on their location and appearance. The doctor may use a small needle to remove some of the cyst's fluid for testing.

Other tests may include:

• X-ray - a test that uses radiation to take a picture of structures inside the body, especially bones
• Ultrasound - a test that uses sound waves to examine the cyst
• MRI Scan - a test that uses magnetic waves to make pictures of structures inside the affected area
• CT Scan - a type of x-ray that uses a computer to make pictures of structures inside the affected area

Treatment
 Many ganglion cysts go away without treatment. If the cyst is very tender or unsightly, you may request treatment from your doctor. Even with treatment, ganglion cysts are likely to return.

Home Treatment

• Ice
• Ibuprofen (Advil, Motrin) or aspirin to relieve pain and swelling
• Note: Do not attempt to smash the cyst with a heavy object (a traditional home remedy). This is unlikely to get rid of the cyst, and very likely to injure you.
• Immobilization - Your doctor may suggest that you wear a splint on your wrist. Ganglion cysts usually get smaller with less activity, and larger with more activity.
• Aspiration -  A needle is put into the cyst to drain the fluid.
• Corticosteroid Injection - A steroid solution is injected into the cyst. This is usually done just after aspiration.
• Surgery  Surgery can be performed to remove the cyst. This is rarely necessary.

Prevention
      There are no guidelines for preventing a ganglion cyst.
