What are shoulder cysts?
Shoulder cysts, also known as synovial cysts or ganglion cysts, are fluid-filled sacs that form in the shoulder joint or surrounding structures. These cysts are usually non-cancerous and are often benign, but they can cause pain, discomfort, and limited shoulder function.
What causes shoulder cysts?
The exact cause of shoulder cysts is not always clear, but they are often associated with underlying joint or tendon problems, such as osteoarthritis or inflammation of the joint lining (synovitis). When these conditions occur, the synovial fluid that lubricates the joint can leak into surrounding tissues, forming a cyst.
What are symptoms of shoulder cysts?
Shoulder cysts may or may not cause symptoms. When symptoms are present, they can include pain, tenderness, swelling, and a visible or palpable lump. The pain may worsen with shoulder movement or activity.
- Location: Shoulder cysts typically develop around the joint or in areas where tendons or ligaments connect to the bone. They may be present on the front, back, or sides of the shoulder.
- Size and appearance: Shoulder cysts can vary in size, ranging from small to larger masses. They are usually soft, round, and fluid-filled, often resembling a small balloon or bubble under the skin.
Depending on their size and location, shoulder cysts can restrict shoulder movement and limit function, particularly if they impinge on surrounding structures or compress nerves.
How are shoulder cysts treated?
If the cyst is small, painless, and not causing significant functional limitations, a healthcare professional may recommend monitoring the cyst without immediate intervention. Some cysts may resolve on their own over time.
Over-the-counter pain medications or corticosteroid injections may be used to alleviate pain and reduce inflammation associated with the cyst. These treatments provide temporary relief and do not remove the cyst itself.
An aspiration involves using a needle and syringe to drain the fluid from the cyst. Aspiration can provide temporary relief from symptoms, but cysts may reoccur.
In cases where the cyst is large, painful, or significantly impacting shoulder function, surgical removal may be recommended. Surgery typically involves excising the cyst and addressing any underlying joint or tendon problems that may have contributed to its formation.
