Ganglion Cysts of the Wrist & Hand
The most common soft tissue mass of the hand and wrist. Complete guide to understanding, when to treat, and treatment options.
Understanding Ganglion Cysts
Ganglion cysts are benign, fluid-filled lumps that most commonly develop near joints and tendons of the wrist and hand. They contain thick, sticky, clear, colorless, mucin-like fluid similar to joint fluid. The word "ganglion" means "knot" in Greek.
Epidemiology: Ganglion cysts account for 60-70% of all soft tissue masses in the hand and wrist. They are most common in women aged 20-40 years. The dorsal wrist is the most common location (60-70%), followed by the volar wrist (20%) and flexor tendon sheath (10%).
Anatomy: Ganglions arise from joint capsules or tendon sheaths via a stalk or pedicle. Dorsal wrist ganglions typically originate from the scapholunate ligament. Volar wrist ganglions often arise from the radiocarpal or scaphotrapezial joints.
Common Locations
Most common type. Arises from the scapholunate interval on the back of the wrist. Often becomes more prominent with wrist flexion.
Located on palm side of wrist, often near the radial artery. Requires careful surgical excision due to proximity to artery and nerves.
Small, firm nodule at the base of a finger (A1 pulley area). Often called "seed ganglion." May cause triggering.
Occult Ganglions: Some ganglions are small and not visible but cause wrist pain. These "occult" dorsal ganglions may require ultrasound or MRI for diagnosis and are a cause of unexplained dorsal wrist pain.
Signs & Symptoms
• Visible lump: Smooth, round, usually 1-3 cm in size
• Location: Over joint or tendon, most commonly dorsal wrist
• Size fluctuation: May enlarge with activity, shrink with rest
• Pain: May or may not be present; dull ache or sharp pain with movement
• Weakness: Grip weakness if cyst is large
• Nerve symptoms: Numbness/tingling if compressing adjacent nerves
Diagnosis
Clinical Examination:
- Inspection: Smooth, round mass over wrist or hand
- Palpation: Firm, non-tender, fixed to deep structures
- Transillumination: Light shines through cyst (confirms fluid content) - pathognomonic
- Mobility: Does not move with tendon gliding (unlike tendon tumor)
Imaging:
- Ultrasound: First-line imaging. Shows cystic structure, confirms diagnosis, identifies stalk
- MRI: For occult ganglions (symptomatic but not visible), or if diagnosis uncertain
- X-ray: Usually normal; may show associated arthritis or bone lesions
Differential Diagnosis: Giant cell tumor of tendon sheath, lipoma, epidermal inclusion cyst, extensor tenosynovitis, carpal boss, bone tumor.
Treatment Options
Many ganglion cysts can be safely observed if not causing significant symptoms.
- 50% of ganglions resolve spontaneously
- May fluctuate in size over time
- Reassurance about benign nature often sufficient
- Activity modification may reduce symptoms
- Wrist splinting can help during symptomatic periods
Needle drainage of cyst contents. Simple, office-based procedure.
- Local anesthesia, large bore needle
- Thick fluid aspirated
- Some add steroid injection (evidence unclear)
- Recurrence rate: ~50%
- Multiple aspirations may be attempted
- Not recommended for volar wrist ganglion (radial artery risk)
Indications:
- Failed aspiration (recurrence)
- Persistent pain or functional limitation
- Cosmetic concerns
- Nerve compression symptoms
- Uncertain diagnosis
Surgical Technique:
Open Excision: Complete removal of cyst and stalk. Must excise portion of joint capsule at origin to reduce recurrence. Recurrence rate: 5-10%.
Arthroscopic Excision: Available for dorsal wrist ganglions. Smaller incisions, direct visualization of joint. Similar recurrence rates to open surgery.
Risks: Recurrence (5-10%), stiffness, scar tenderness, nerve injury (sensory branches), wound complications.
