Ganglion Cysts
Meaning of ganglion cyst
Ganglion cysts are the most common type of lumps which are most commonly found along the wrist. However, they can be seen in various other sites like- ankles, feet and palm. They arise due to leakage of synovial fluid from a joint or tendon sheath and contain a glary, viscous fluid.
Clinical features
The patient, often a young adult, presents with a painless lump. Though occasionally, there is a slight ache and weakness. The lump is well defined, cystic and not tender and can sometimes be Trans illuminated. It doesn’t move with the tendons. The back of the wrist is the most common site; less frequently a ganglion emerges alongside the radial artery on the volar aspect. Occasionally a small, hidden ganglion is found to be the cause of compression of the deep branch of the ulnar nerve.
Risk factors
- Even though ganglion cysts can occur to anyone, they are most commonly found in women between the ages of 20 to 40 years.
- People suffering from wear and tear arthritis near the joints of fingernails have higher chances of developing ganglion cysts.
- Joints or tendons which have been a part of an injury in the past can develop the condition.
Treatment
Treatment is usually unnecessary. The lump can safely be left undisturbed; it often disappears spontaneously. However, it can be aspirated to reassure the patient. A complex volar ganglion might be better aspirated under ultrasound control due to the proximity of the radial artery and vulnerable nerves. If it becomes troublesome and certainly if there is any pressure on a nerve, operative removal is justified.
