Ganglion Cyst Topic Guide
Ganglion Cyst: A ganglion cyst is a swelling or tumor on a joint or tendon sheath. Ganglionic cysts form on the elbow, knee, foot, shoulder, wrist, toe or finger. Symptoms and signs include a mass that changes in size, is somewhat painful, and the pain is made worse by joint motion. Though many ganglion cysts disappear on their own, cysts may be treated by aspirating the cyst's contents or surgical removal.
Magnetic Resonance Imaging (MRI) Magnetic resonance imaging (MRI) is a scanner that takes cross-sectional images of the body. It is used to evaluate tissues of the head, neck, chest, limbs, abdomen, and pelvis. MRI is a very safe procedure; sedation may be used for infants, small children, or adults who are claustrophobic.
