1-15. GANGLION
A ganglion may be a collection of nerve cell bodies outside of the brain or the spinal cord. Here, the meaning is a cystic swelling resembling a tumor. This cystic swelling can occur on a tendon sheath or a joint capsule. Ganglions can be caused by contusions, repeated strains, or a weak area in a joint capsule or tendon sheath. Ganglions are most common in the wrist.
a. Signs/Symptoms of Ganglion. A firm lump or protrusion and a non-tender cyst are indications of a ganglion.
b. Treatment of a Ganglion. If the tumor is benign, leave it alone. It can be aspirated. If the ganglion is a cyst which is surgically removed, there is a fifty percent chance that the cyst will return.
