An abnormal closed cavity or sac lined with tissue and filled with fluid that originates in the bone tissue and is usually noncancerous (benign). Bone cysts are rare, tend to occur in children between the ages of 5 and 15 years, and generally develop in long bones, such as the upper arm bone (humerus) or thighbone (femur), making the affected bones more susceptible to fracture. Bone cysts may be diagnosed by means of X rays, including CT (computed tomography) scanning or MRI (magnetic resonance imaging). Surgery to remove bone cysts may be recommended to prevent fracture of the bone involved. Some bone cysts respond to being drained (which is called aspiration) and being injected with a corticosteroid.
A cystic mass in bone, usually a normal variant or a benign tumor.
An unusual hollow space within a bone. Bone cysts generally form at a specific extremity of a lengthy bone and can often be stumbled upon incidentally following a fracture occurring in the vicinity of the cyst. Typically, a minor surgical procedure is performed to eradicate the cyst by scraping it out, subsequently replenishing the void with bone fragments. This method is commonly effective in treating the condition; however, it is worth noting that numerous small cysts may not necessitate any form of medical intervention.
