Ganglion cysts are noncancerous lumps that usually appear along the tendons or joints of the wrist or hand but can also occur in the ankles and on the feet. The cyst is filled with a jelly-like fluid and may be soft or firm to the touch.
Causes of a Ganglion cyst
The exact cause of ganglion cysts is not known. They are more common in women and people between the ages of 20 and 40 but can occur in patients of all ages.
Symptoms of a Ganglion cyst
Ganglion cysts are usually painless, although they may cause discomfort or aching if they press on a nerve. They may also limit range of motion in the affected joint. Some ganglion cysts may disappear on their own without treatment, while others may require medical intervention.
Diagnosing a Ganglion cysts
A ganglion cyst diagnosis is usually based on the location of the lump and its appearance. Light will often pass through these lumps, and this may assist in the diagnosis. Dr Singh may request x-rays in order to look for evidence of problems in adjacent joints. Other imaging tests such as ultrasound can be helpful to diagnose a ganglion cyst because the uniform dark appearance of the fluid in the cyst is often characteristic. They are also visible on MRI (magnetic resonance imaging), which is often helpful when the cyst is suspected but cannot be easily felt during the exam. Dr Singh will also ask you questions about your medical history when diagnosing your condition.
Treating Ganglion cysts
Treatment options for ganglion cysts include:
- Observation: If the cyst is not causing any pain or discomfort, it may be left alone and monitored over time.
- Aspiration: In this procedure, a needle is inserted into the cyst to remove the fluid. This may be done if the cyst is causing pain or limiting range of motion in the affected joint.
In some cases, surgery may be necessary to remove the cyst. This may be recommended if the cyst is causing significant pain or interfering with hand function.
