There are four main types of bone cysts. A nonossifying fibroma NOF is a central portion of the bone that has failed to form into hard bone but instead is fibrous in nature.
These are not painful. Most lesions spontaneously resolve without treatment. A NOF is the most common benign bone tumor in children and commonly occurs in the lower extremities in children between the ages of five and 15 years of age.
Some researchers estimate that up to 40 percent of all children have a NOF at some point. A fibrous cortical defect is a benign bone lesion that forms in the outer edge or cortex of the bone.
These most commonly occur in the lower extremities and usually resolve spontaneously. Growth plates are what enable children to grow. The cysts often cause nearby bones to thin, which can lead to a break fracture. Cysts that are less than 2 inches about 5 centimeters long or wide may heal and may disappear as the fracture heals. Cysts that are more than 2 inches long or wide, particularly in children, may require treatment. To diagnose unicameral bone cysts, doctors usually do x-rays X-rays A doctor can often diagnose a musculoskeletal disorder based on the history and the results of a physical examination.
Most of the time, x-rays are enough to make the diagnosis, but sometimes other imaging tests, such as magnetic resonance imaging Computed tomography CT and magnetic resonance imaging MRI A doctor can often diagnose a musculoskeletal disorder based on the history and the results of a physical examination. Most often, these cysts are treated with injections of corticosteroids often repeatedly , with processed bone putty, or with synthetic bone substitutes.
Sometimes treatment is surgery to remove the contents of the cyst from the bone by scraping it with a scoop-shaped instrument curettage and transplantation of bone from one site to another bone grafting.

The Manual was first published in as a service to the community. ABCs are not known to go away without treatment. We have staff available to discuss the needs of families traveling to Columbus, Ohio, from other cities in the United States and other countries around the world. A year-old girl, who was succeeding in high school both socially and academically, began suffering with frequent neck pain and headaches.
She was able to push through her pain until it became increasingly worse when she tilted her head to the left. A CT scan showed an aneurysmal bone cyst with complete destruction of the left half of her second cervical vertebra and no bony protection over the spinal cord in this dangerous location.
A neurosurgeon described the most optimistic surgical option, which included extensive surgery, to remove the diseased bony segment in this highly sensitive location, and permanent spinal fusion, with hope for no recurrence. She has full mobility and use of her neck, without recurrence of her aneurysmal bone cyst tumor.
Our interventional radiology team has long been the national leaders of innovation in minimally invasive radiologic procedures for conditions such as Aneurysmal Bone Cysts, Dermoid Cyst Ablation, Lymphatic Malformation and Salivary Gland Ablation. Skip to Content. Urgent Care. In This Section. Aneurysmal Bone Cyst An aneurysmal bone cyst is a highly destructive benign bone tumor, representing 1 to 6 percent of all solid bone tumors. Meet Dr.
Murakami Improving children's lives through innovative imagining. Close Video. Patient Outcomes. What is an Aneurysmal Bone Cyst? What are the Symptoms of an Aneurysmal Bone Cyst?
Are ABCs Dangerous? Animation: Treating Aneurysmal Bone Cysts Using advanced imaging technology, the Interventional Radiology team at Nationwide Children's can insert medicine directly into an aneurysmal bone cyst through small needles or probes. What Causes an Aneurysmal Bone Cyst? Are ABCs Hereditary? How is an Aneurysmal Bone Cyst Diagnosed? Above, a patient undergoing aneurysmal bone cyst treatment at Nationwide Children's Hospital.
How long will the procedure take? Are there any risks to the procedure? Interventional radiologists at Nationwide Children's treat aneurysmal bone cysts by removing fluid from the cyst and replacing it with medicine called Doxycyline. Treatment is done under general anaesthetic. You will not usually need to stay in hospital overnight.
It's quite common for bone cysts to come back, especially in the first couple of years after treatment. The exact cause of bone cysts is unknown.
