Gangrene

Diagnosis

A healthcare provider typically begins diagnosing a ganglion cyst with a physical examination. During the exam, they may press on the cyst to check if it causes pain. They might also shine a light through it to see whether the lump is solid or filled with fluid.

Imaging tests such as an X-ray, ultrasound, or MRI can help confirm the diagnosis and rule out other possible conditions like arthritis or tumors.

Sometimes, the healthcare provider may use a needle to draw fluid from the cyst. The fluid inside a ganglion cyst is usually thick and clear, which helps confirm the diagnosis.

Treatment

Ganglion cysts are often harmless and may not need treatment, especially if they are painless and do not interfere with movement. In many cases, the cyst may disappear on its own over time. Your healthcare provider may suggest monitoring the cyst for any changes in size or symptoms.

If the cyst causes discomfort or limits movement, treatment options may include:

• Keeping the joint still
  Limiting activity can help prevent the cyst from growing larger. Wearing a brace or splint may reduce pressure on surrounding nerves and relieve pain. However, prolonged use of a brace or splint can weaken nearby muscles.

• Draining the cyst
  The healthcare provider may use a needle to drain fluid from the cyst in a procedure called aspiration. This can reduce swelling and relieve symptoms, but ganglion cysts often return after drainage.

• Surgery
  Surgery may be recommended if other treatments do not work. The procedure involves removing both the cyst and the stalk that connects it to the joint or tendon. Although surgery is generally effective, in rare cases, it may cause injury to nearby nerves, blood vessels, or tendons. There is also a chance that the cyst could return even after surgery.
