Brain cysts can contain pus, blood, or cerebrospinal fluid and be benign or malignant. Even brain cysts that are not cancerous can cause problems, depending on their size and location.
Small cysts that are not growing and are unlikely to cause problems may require monitoring. Cysts that press on brain tissue and cause nausea, vision issues, or headaches may require surgery.
Some brain cysts are present from birth, while others can appear after an injury or infection.
Spinal cysts are more common in people over 50and may result from spinal instability or degeneration.
They are common in the lower part of the spine, particularly in people who have arthritis or disk disease. Treatment can involve anti-inflammatory medication, rest, drainage, or steroid injections, though these are generally short-term solutions.
If spinal cysts become large or impair movement, surgery may be recommended for longer-lasting relief.
