핵심 개념

• Ganglion Cyst — A benign, fluid-filled cyst that arises from a joint capsule or tendon sheath, most commonly occurring on the dorsal wrist and containing thick, gelatinous mucin-rich material.
• Dorsal Wrist — The back of the wrist, which is the most frequent site for ganglion cysts, often originating near the scapholunate ligament due to anatomical vulnerability.
• Scapholunate Ligament — A key ligament connecting the scaphoid and lunate bones in the wrist, frequently serving as the anatomical origin for dorsal wrist ganglion cysts.
• Transillumination — A diagnostic physical examination technique where a light source is shone through a cyst; ganglion cysts typically transilluminate due to their fluid-filled nature, helping differentiate them from solid tumors.
• Mucinous Material — The thick, gelatinous, high-viscosity fluid rich in hyaluronic acid and other mucopolysaccharides that fills ganglion cysts, often described as having a "jelly-like" consistency.
