Aneurysmal bone cyst of the clavicle: A case report

Abdulrahman Jalwi Korkoman et al. Int J Surg Case Rep. 2023 Sep.

Abstract

Introduction: An aneurysmal bone cyst (ABC) is a locally aggressive primary bone neoplasm. ABC of the clavicle is rare with only a few reported cases in the literature.

Presentation of case: We report the case of a 10-year-old boy who presented with an ABC at the right acromial end of the clavicle. The patient underwent intralesional curettage and allogenic bone grafting. Moreover, the patient's arm was placed in a sling for 2 weeks postoperatively. The patient had a satisfactory outcome after 11 years, with excellent Toronto Extremity Salvage, Quick-Dash, and Musculoskeletal Tumor Society scores.

Discussion: Clavicular ABCs are uncommon. Early diagnosis helps to prevent pathological fractures. Adjuvant therapies might help decrease recurrence.

Conclusion: ABC should be considered an important differential diagnosis for clavicular swelling and masses. The best results can be achieved using curettage and void-filled bone grafts.

Keywords: Aneurysmal bone cyst; Benign tumor; Case report; Clavicle; Orthopedic oncology; Shoulder.
