Aneurysmal Bone Cyst Treatment Pune
We at Sancheti Hospital treat Aneurysmal Bone Cysts using advanced imaging, surgical curettage, and grafting techniques for lasting bone strength.
Overview
Aneurysmal Bone Cysts (ABCs) are rare, noncancerous bone tumors that contain blood-filled spaces within the bone. The name “aneurysmal” comes from the bulging blood vessel walls that help form these cysts, while “cyst” refers to the fluid-filled cavities inside.
Even though ABCs are benign and don’t spread like cancer, they can grow quickly and become large. This rapid growth can cause serious problems because these cysts expand and weaken the bone structure.
These bone tumors are uncommon, making up only a small portion of all bone tumors. They mainly affect children and young adults, especially those under 20 years old. While ABCs can develop in almost any bone, they’re most often found in:
- Long bones of arms and legs (femur, tibia, humerus)
- Spine (vertebrae)
- Pelvis bones
Symptoms
Symptoms of Aneurysmal Bone Cysts vary depending on their size and location. Some cysts grow slowly with little discomfort, while others expand rapidly, causing significant problems. Early recognition is important for proper diagnosis and treatment.
Common symptoms include:
- Lump: A visible or feelable lump with swelling around the affected area
- Pain: Ongoing or worsening pain in the affected bone that may get worse with movement
- Swelling and Tenderness: The area around the cyst may look swollen and feel tender, sometimes warm or red
- Bone Weakness: As the cyst grows, it weakens the bone, increasing the risk of fracture from minor injuries
- Limited Movement: If the cyst is near a joint, it can restrict movement and make activities difficult
- Neurological Symptoms: When ABCs develop in the spine, they can press on nerves, causing numbness, tingling, muscle weakness, or in severe cases, paralysis
Causes
The exact cause of Aneurysmal Bone Cysts remains unknown, but several factors may contribute to their development:
Vascular Problems: The main theory suggests ABCs form when blood vessels in the bone become abnormal. This creates increased pressure and expansion within the bone, leading to bone damage.
Genetic Changes: Research shows that about 65-70% of primary ABCs involve changes in the USP6 gene. This genetic change activates tumor-causing genes that trigger destructive tissue growth. These mutations usually happen spontaneously rather than being inherited.
Pre-existing Bone Problems: About 30% of ABCs develop as secondary conditions, meaning they’re caused by other existing bone tumors or conditions like fibrous dysplasia, giant cell tumors, or osteoblastomas.
Injury or Trauma: While trauma alone doesn’t directly cause ABCs, some researchers believe that bone injuries or blood collection under the bone membrane might trigger changes that lead to cyst formation.
Hormonal Changes: Since most ABCs occur during childhood and adolescence, periods of rapid growth and hormone changes might influence their development.
Risk Factors
While the exact causes are still being studied, certain factors increase the likelihood of developing ABCs:
- Age: ABCs primarily affect children and young adults, with most cases diagnosed before age 20
- Gender: Some studies suggest a slight female predominance, while others show equal distribution
- Pre-existing Conditions: People with other bone conditions or tumors have a higher risk of developing secondary ABCs
Diagnosis
Diagnosis of Aneurysmal Bone Cysts involves several steps to ensure accurate identification and rule out other conditions, especially cancerous ones.
Physical Examination: Healthcare providers examine any visible lumps, swelling, pain, or movement limitations in the affected area.
Imaging Tests:
- X-rays: Usually the first imaging test, showing bone-destroying lesions with thin borders and internal divisions
- CT Scans: Provide detailed pictures of bone destruction and help assess complex locations like the spine
- MRI Scans: Often considered the best imaging choice, showing detailed internal characteristics including “fluid-fluid levels” that strongly suggest ABCs
Biopsy: Essential for confirming diagnosis and ruling out other conditions, especially malignant tumors. A small tissue sample is examined under a microscope, and genetic tests may be done to look for USP6 gene changes.
Types
Aneurysmal Bone Cysts are classified in several ways:
Primary vs. Secondary:
- Primary: Develops spontaneously without underlying bone problems (70% of cases)
- Secondary: Occurs as a complication of other existing bone tumors (30% of cases)
Activity Level:
- Active: Contained within bone but can deform it, shows signs of growth
- Aggressive: Extends beyond bone into nearby tissues, expands rapidly
- Solid Variant: Consists mainly of solid tissue rather than blood-filled spaces
Stages
ABCs are categorized by their clinical activity using staging systems:
- Stage 1 (Latent): Usually discovered accidentally, no symptoms, contained with clear borders
- Stage 2 (Active): Cause symptoms and grow steadily, may be feelable with some expansion
Stage 3 (Aggressive): Cause significant discomfort, rapidly expanding, destroy bone and extend into surrounding tissues
Treatment
Treatment for Aneurysmal Bone Cysts aims to remove the cyst, relieve symptoms, prevent fractures, and minimize recurrence. The approach depends on the cyst’s size, location, aggressiveness, and patient’s age.
Surgical Options:
Curettage with Bone Grafting: The most common treatment. Surgeons scrape out the cyst contents and fill the cavity with bone graft material to strengthen the bone and promote healing.
En Bloc Resection: Involves removing the entire cyst with surrounding healthy bone. This has excellent success rates but is usually reserved for specific cases due to its complexity.
Non-Surgical Options:
Sclerotherapy: A minimally invasive treatment where special chemicals are injected directly into the cyst to promote healing. This treatment has shown good success rates with less complications than surgery.
Arterial Embolization: Blocks blood vessels that supply the tumor, performed by radiologists. Often used for ABCs in hard-to-reach locations.
Other Treatments:
- Cryotherapy: Freezing the cyst with liquid nitrogen
- Medical Therapies: Medications like denosumab to strengthen bones
- Radiation Therapy: Rarely used due to significant risks, especially in children
Rehabilitation
Recovery after treatment varies based on the treatment type, cyst size and location, and the patient’s overall health.
Healing Time: Surgical treatment typically requires 3-6 months for complete bone healing. Weight-bearing bones may need crutches or braces during recovery.
Physical Therapy: Often essential for regaining strength, mobility, and range of motion in the affected area.
Activity Restrictions: Patients usually avoid strenuous activities until the bone completely heals. Spine cases may have additional restrictions.
Follow-up Care: Regular imaging tests are necessary for several years to monitor healing and check for recurrence.
Complications
Although ABCs are benign, they can cause serious problems if left untreated:
- Pathologic Fracture: Bone fractures from minor trauma due to bone weakening
- Growth Problems: In children, cysts involving growth plates can affect normal bone development
- Nerve Damage: Spine ABCs can press on nerves, causing numbness, tingling, or paralysis
- Persistent Pain: Ongoing pain and swelling that affects quality of life
- Recurrence: ABCs can return after treatment in about 20% of cases, usually within the first 1-2 years
Treatment-Related Complications:
- Surgery: Blood loss, infection, nerve damage
- Embolization: Tissue injury, nerve problems
- Radiation: Risk of secondary cancers
Prevention
Since the exact cause of ABCs is unknown, there are no specific prevention methods. However, general approaches can help:
- Regular medical check-ups for early detection
- Prompt treatment of bone injuries
- Maintaining good bone health through proper nutrition and exercise
Monitoring existing bone conditions for early cyst detection
Living With Aneurysmal Bone Cysts
Living with ABCs requires ongoing care and monitoring. The prognosis is generally good with appropriate treatment, but long-term management focuses on preventing recurrence and maintaining bone function.
Follow-up Care: Regular appointments with imaging studies are crucial due to recurrence risk, especially in the first few years after treatment.
Activity Modification: Certain physical activities may need to be modified based on the cyst’s location and healing progress.

Frequently Asked Questions
How long will my child need to stay off sports after ABC treatment?
Most children can return to sports within 4-6 months after surgical treatment, but contact sports may require 6-12 months. Your doctor will confirm when the bone has healed completely through X-rays.
Will my child's growth be affected if the ABC is near the growth plate?
If caught early and treated properly, most children maintain normal growth. However, ABCs very close to growth plates may cause slight length differences, which your surgeon will monitor closely.
Should I get a second opinion before choosing treatment?
Yes, especially for complex cases or spine ABCs. Different specialists may recommend different approaches, and a second opinion can help you make the best decision for your situation.
What are the warning signs that an ABC might be coming back?
Watch for returning pain at the original site, new swelling, or decreased movement. Most recurrences happen within 2 years, so report any new symptoms to your doctor immediately.
