Ganglion Cysts: Causes, Symptoms, and Treatment

Ganglion cysts are common lumps found in the hand and wrist, often developing adjacent to joints or tendons. These cysts can appear in various locations, including:

  • Top of the wrist
  • Palm side of the wrist
  • Base of the finger on the palm side
  • Top of the end joint of the finger

Ganglion cysts typically resemble a water balloon on a stalk, filled with clear fluid or gel. While the exact cause of ganglion cysts is unknown, they may form due to joint or tendon irritation or mechanical changes. They can occur in individuals of all ages and may fluctuate in size or even disappear completely over time. These cysts are non-cancerous and do not spread to other areas of the body.

How Are Ganglion Cysts Diagnosed?

Diagnosis is often based on the appearance and location of the bump. Ganglion cysts are typically oval or round in shape and may be soft or firm to the touch. To investigate any underlying issues in the adjacent joints, the doctor may request an x-ray. Cysts located at the end joint of the finger are sometimes associated with an arthritic bone spur.

Treatment Options for Ganglion Cysts

In many cases, ganglion cysts do not require surgical intervention and can be managed conservatively. Treatment options include:

  • Observation: Many ganglion cysts resolve on their own without the need for treatment.
  • Splints and anti-inflammatory medication: Used to reduce pain and limit swelling.
  • Aspiration: The fluid within the cyst may be removed using a needle, which can help decompress the cyst.
  • Surgery: If the cyst is painful, limits activity, or recurs after aspiration, surgical removal may be recommended. This involves removing the cyst along with the portion of the joint capsule or tendon sheath. Traditional and arthroscopic techniques are commonly used for wrist ganglion cysts.

Your doctor will discuss the best treatment options based on the location, size, and symptoms of the cyst during your appointment.
