Ganglion Cyst
Diagnosis

Doctors are often able to diagnose a ganglion cyst based on its appearance and location. In addition, because the fluid inside a ganglion cyst is translucent, the doctor may hold a flashlight to the cyst to see if light shines through. Your doctor may also remove the cyst fluid to confirm the diagnosis.

X-rays are often reserved for cases in which other conditions, such as osteoarthritis, bone spurs, bone tumors or fractures, are suspected. However, X-rays may also be used to determine if there is cyst-related damage to wrist bones.
