Ganglion cysts are benign subcutaneous tissue tumors (growths) in the hand in direct contact with the tendon sheath or joint capsule.
How does it develop?
The exact cause is unknown.
It is considered that hand trauma can be a cause, or that disturbed flow of liquids through the tendon sheaths and joints with the combination of increased pressure in the area contributes to development of ganglion cysts.
Symptoms and signs
We make them out as lumps of to a couple of cm in size that are usually located in the back side of the wrist. Apart from this location, they can be found in the sides and the backs of fingers.
They can reduce the function of the hand, they rarely hurt, and the patients usually complain about the compromised esthetic appearance.
How is it diagnosed?
Diagnosis is made by a clinical examination and patient history (interview).
Biopsy can be done, although rarely, if the diagnosis is unclear, and a hand X-ray can be done in order to see the condition of the wrist joint .
How is it treated?
Ganglion cysts can spontaneously resolve in about 50% of cases, so surgical treatment shouldn’t be rushed.
Immobilization of the wrist can be attempted, beacuse it can help in a certain number of patients.
Yet, if it creates functional issues and pain, they can be easily treated by :
- Injection aspiration
- Surgical excision
- 3. Endoscopy
