Ganglion

 

Definition

 

A benign cystic swelling occurring over a joint or tendon sheath.

Aetiology

 

It is thought that there is herniation of synovial tissue from a joint capsule or tendon sheath. The ganglion has a fibrous capsule and contains mucoid material.

 

Clinical features

 

A ganglion may present as a swelling or pain commonly around the wrist or the dorsum of the hand. On examination the swelling transilluminates.

 

Management

 

Ganglia may resolve or may be recurrent. Aspiration and injection of a crystalline steroid may be useful, and injection of hyaluronidase into the lesion prior to aspiration may improve results. Surgical removal is effective, although recurrence may still occur.
