Aneurysmal bone cyst of the rib: a case report

An aneurysmal bone cyst involving the rib is very rare. Forty-four cases have been reported in the literature. Primary neoplasms of the ribs are uncommon and malignant tumours are significantly more common than benign tumours in this location. The condition is a rare benign, progressive bone tumour. The aetiology and natural history are unknown. The Authors report the case of a 38-year-old man with an aneurysmal bone cyst of the right 6th rib, treated by en-bloc resection. The patient has been followed up now for ten years with no signs of recurrence.
