Dr. Ebraheim’s educational animated video describes ganglion cysts - Ganglion Cyst of the Wrist. Follow me on twitter: https://twitter.com/#!/DrEbraheim_UTMC Ganglion cysts are fluid filled cysts that are benign (not cancerous) and will not spread. Ganglion cysts may vary in size from time to time, and it may grow, but it usually does not cause any harm, and the patient is usually more concerned about how the cyst looks. When these cysts pressure a nerve, an artery, or a tendon it can cause a problem. Ganglion cyst of the wrist is usually classic. This type of cyst transilluminates, therefore an MRI is usually not needed. If an MRI is done for whatever reason, it will usually show a fluid signal inside the cyst. Ganglion cysts of the wrist can be either dorsal or volar. The dorsal type of ganglion cyst is common. The volar type is rare. The volar ganglion could compress the radial artery this might compromise the circulation in the hand. The dorsal type arises from the scapholunate articulation. The volar type arises from the radiocarpal joint, which is the wrist joint itself. A bump or a mass that is well defined, localized, smooth, and not attached to the skin. The dorsal ganglion cyst is more obvious with flexion of the wrist. The volar ganglion cyst is more obvious with extension of the wrist. This ganglion cyst of the wrist is usually asymptomatic, and the patient is usually more concerned about the looks and the cosmetics. When there is a volar ganglia of the wrist, check the nerves of the hand and do the Allen’s test to see if this cyst is compromising the circulation. Ultrasound is a good study to see the relationship between the cyst and the radial artery in volar ganglion cyst. Ultrasound may be needed during aspiration of the ganglion cyst because the ganglion is near the artery. Surgery is usually done for the ganglion cyst if there are severe symptoms, neurovascular compromise, or if the patient complains of pain. High recurrence rate with excision of the volar ganglion cyst (about 20%). Do the Allen’s test to check the blood flow of the hand before doing excision of the volar ganglion cyst.
