From the Research
Yes, ganglion cysts can definitely appear on the ankle, as they can develop along tendons or joints in areas with frequent movement, including the ankle. These fluid-filled sacs typically form on the top of the foot, around the ankle joint, or along the tendon sheaths, and usually appear as round or oval lumps that are firm to the touch but not solid 1. The exact cause of ganglion cysts is not fully understood, but they often result from trauma, joint or tendon irritation, or a weakness in the joint or tendon covering.
Key Characteristics of Ankle Ganglion Cysts
- They contain a thick, clear, jelly-like fluid and can vary in size from pea-sized to larger
- Most ankle ganglion cysts are painless, though some may cause discomfort, especially if they press on nearby nerves or interfere with movement
- Treatment options range from watchful waiting (as many resolve on their own) to aspiration (draining the fluid) or surgical removal for persistent or problematic cysts
Treatment Considerations
- According to a recent study, surgical excision has been shown to have a lower recurrence rate (17.6%) compared to aspiration alone (78.1%) or aspiration and steroid injection (62%) 1
- Ultrasound-guided aspiration and injection of corticosteroid is a useful and minimally invasive alternative to surgery for managing intraneural ganglion cysts 2
- If you notice a lump on your ankle that persists or causes pain, it's advisable to have it evaluated by a healthcare provider to confirm the diagnosis and discuss appropriate management.
