Ganglion Cysts of the Hand

• Ganglion cysts can develop in tendon sheaths, joints, and ligaments throughout the hand, according to the Annals of the Rheumatic Diseases 1
• The American College of Radiology recommends ultrasound as the initial imaging modality to confirm the fluid-filled nature of ganglion cysts, with MRI typically reserved for suspected occult ganglion cysts or when there's concern about solid tumors 2, 3, 4
