But while sitting, the spinal canal naturally expands a bit, and this helps to relieve the excess pressure from spinal stenosis and improves the condition.īesides these, patients with a synovial cyst may experience one or more of the following symptoms (Trummer et al., 2001): This results in a fully upright posture in patients that additionally pressures the spinal disc and nerve roots during standing and walking. Although they feel good while sitting (Acharya et al., 2006). However, many patients suffer from back and leg pain while standing and walking. Some patients may remain asymptomatic, which means they won’t experience any signs or symptoms. Symptoms of a synovial cyst depend on the size and location of the cyst. What are the Common Symptoms and Causes of Synovial Cysts?
This ultimately results in epidural compression of the spinal cord.
In some reports, patients with certain joint conditions like rheumatoid arthritis develop a synovial cyst, and a history of trauma causes cyst enlargement or hemorrhage into the synovial cyst cavity. Most of the synovial cysts occur among adults older than 65 years of age due to the degeneration of the facet joint in their spine (Splavski et al., 2019). But research estimates almost 90 percent of synovial cysts develop in the facet joints of the lumbar spine. These cysts may develop anywhere in the body around any joint. Management of these lesions usually conservative, but sometimes the physician performs percutaneous aspiration or lumbar decompression procedure and fusion to improve the condition. Synovial cysts sometimes located extradural in the lumbar spine and produce symptomatic radiculopathy and back pain. These cysts typically non-malignant (benign) in nature and non-cancerous. Synovial cysts may remain asymptomatic for a long time and occur as a consequence of rheumatoid arthritis or neuropathic arthropathy. These mucin-filled lesions with a fibrous capsule (approximately 0.5- to 2-cm in size) may occur at many joints along the spine (Splavski et al., 2019). Synovial cysts or ganglion cysts refer to a small fluid-filled lump that arises from joints or tendon sheaths.
