Introduction: Aneurysmal bone cyst (ABC) is an expansile tumor like benign lesion. These lesions are commonly found in children and young adults. Most common sites for aneurysmal bone cyst are long bones including vertebral column. Such lesions in ribs, especially in elderly is extremely a rare condition. Case report: We reported a case of a 58 years old woman with an aneurysmal bone cyst of right 11th rib and she was treated with En bloc chest wall resection. She was presented with the history of right chest wall swelling which was gradually increasing in size with pain. The pathological findings confirm the diagnosis of aneurysmal bone cyst. Discussion: ABC accounts for only 5% of all primary bone tumors. ABC is not a true neoplasm, cyst or aneurysm. ABC is mainly present in metaphysis of long bones like femur, tibia, vertebrae and pelvis. Presence of ABC in rib is a rare condition. ABC can be present in any rib but its presence in lower three ribs has never been reported before. In our case the age of the patient and the site of ABC both are unusual since it is extremely rare in the elderly and it is never been reported before in lower three ribs. Conclusion: Aneurysmal bone cyst in ribs especially in elderly patients is a rare benign tumor like lesions. Such cyst has never been reported before in lower three ribs. En bloc resection can be the best treatment for the cure.
