Ganglion Cysts
A fluid-filled lump around a wrist or hand joint or tendon that may cause pain, tenderness or discomfort with movement.
A ganglion cyst is a collection of joint or tendon-sheath fluid in a small sac. It may change size, become more noticeable with activity, or disappear and return.
Many ganglion cysts are harmless and can be watched. The decision to treat depends on pain, pressure, movement, appearance, uncertainty about the diagnosis and whether the cyst returns.
Loading anatomy
Common symptoms
- A noticeable lump around the wrist or hand
- Pain or tenderness with pressure or movement
- Discomfort when gripping or leaning on the wrist
- A lump that changes size or becomes more visible after activity
- Occasional numbness or weakness when a cyst presses on a nearby structure
Causes and contributing factors
- A connection with a joint or tendon sheath that allows fluid to collect
- Wrist or finger-joint irritation and arthritis may contribute
- Previous injury can be associated, although many cysts have no clear trigger
- The location and depth of the cyst influence symptoms and treatment
How it is evaluated
The lump is examined for location, size, movement, tenderness and its relationship to nearby joints, tendons and nerves. A cyst is not assumed from appearance alone.
- Examination of the lump and the joint or tendon beside it
- Assessment of wrist or finger movement and grip function
- Ultrasound or MRI when the diagnosis or depth is uncertain
- X-rays when arthritis, a bone problem or another source of pain is suspected
Nonsurgical treatment
A ganglion that is not painful or limiting function can often be observed. Symptoms may settle even if the lump remains visible.
- Observation with a review plan
- Activity modification when pressure or repetitive loading aggravates symptoms
- A wrist or finger support for short periods when it reduces painful movement
- Anti-inflammatory medication where appropriate and safe
- Aspiration in selected cysts, with an explanation that recurrence is possible
Surgical treatment
Surgery may be considered for persistent pain, repeated recurrence, pressure on a nearby structure or a cyst that interferes with function. The cyst and its connection are addressed together where possible.
- Excision of the cyst and its stalk or connection when identified
- Arthroscopic or open approaches depending on location and anatomy
- Inspection of the joint or tendon sheath for the source of the fluid
- Reassessment when a lump returns or does not behave like a ganglion
Recovery
Recovery varies with the location of the cyst and the approach used. The incision may be sensitive, and wrist or finger motion is increased gradually as swelling settles.
- Gentle motion to avoid unnecessary stiffness
- Temporary limits on pressure, gripping or heavy lifting
- Scar and swelling care when the cyst was close to a joint or tendon
- Monitoring for recurrence or persistent pain from another source
When to seek urgent care
Seek immediate medical attention - an emergency department - if you experience:
- A rapidly enlarging, red, hot or severely painful lump
- New numbness, weakness or loss of circulation in the hand or finger
- A lump that appears after a significant injury with severe pain or deformity
This list is not exhaustive. If something about your hand worries you, have it looked at.
Frequently asked questions
Do all ganglion cysts need to be removed?
No. Many can be watched if they are not painful or limiting function. Treatment is considered when symptoms, recurrence or uncertainty makes observation less useful.
Can a ganglion cyst come back after treatment?
Yes. Recurrence can occur after aspiration or surgery, especially when the connection to the joint or tendon sheath is difficult to identify or when the underlying joint remains irritated.
Related conditions
Thumb-Base Arthritis
Wear of the joint at the base of the thumb, where the thumb meets the wrist, causing pain with pinching, gripping and twisting.
Wrist Fractures
Breaks involving the end of the forearm bones or the small bones of the wrist, most often after a fall onto an outstretched hand.
Complex Wounds
Wounds of the hand or upper limb that will not heal on their own, or that expose bone, tendon, joint or hardware and need durable coverage.
