A ganglion cyst is a noncancerous lump that often develops along the tendons or joints of the wrists or hands, but may also appear on the feet. These fluid-filled cysts can quickly appear, disappear, and change size, causing distress or fascination more than pain or functional limitation.
Etiology and Pathophysiology[edit]
The exact etiology of ganglion cysts is unknown, but they may arise from trauma, chronic tissue irritation, or degenerative changes in the surrounding joint or tendon. The cyst forms when the tissue surrounding a joint or tendon bulges out, filling with a thick, clear fluid similar to synovial fluid.
Clinical Presentation[edit]
Most ganglion cysts are round or oval and are typically 1-3 centimeters in diameter. They are usually soft and mobile, with a consistency similar to a rubber ball. While many ganglion cysts are asymptomatic, some can cause pain, especially after acute or repetitive trauma. They may also interfere with joint movement.
Diagnosis[edit]
Diagnosis of a ganglion cyst is typically made through a combination of medical history, physical examination, and imaging studies. Ultrasonography and magnetic resonance imaging (MRI) can help confirm the diagnosis and rule out other potential causes of the lump, such as a tumor.
Treatment[edit]
- Treatment of ganglion cysts is often unnecessary, as they may resolve spontaneously. If the cyst causes pain or limits activity, however, treatment options include:
- Immobilization: Activity often causes the ganglion cyst to increase in size, thus increasing pain. Immobilization can cause the cyst to decrease in size.
- Aspiration: This involves using a needle to remove the cyst's fluid. However, cysts recur in the majority of patients following this treatment.
- Surgery: This is usually reserved for painful cysts that have not responded to other treatments or if the diagnosis is uncertain. The recurrence rate after surgical removal is much lower than that after aspiration.
Prognosis[edit]
The prognosis for a ganglion cyst is generally good, although recurrence is common. The cysts are not cancerous and do not pose a risk for malignancy.
