Management Aneurysmal Bone Cyst Using Methylprednisolone Sclerotherapy: A Case Series

The aneurysmal bone cyst (ABC) is a benign intraosseous or rare tumour-like lesion. The ABC therapy methods have evolved over time. However, the best management is still debatable. Surgical curettage shows high recurrence rates ranging from 30% to 50%. In the recent decade, Percutaneous sclerotherapy has developed as an excellent therapy technique for aneurysmal bone cysts. Therefore, this study aims to report the clinically and radiologically outcome using methylprednisolone in patients with ABC. There are two cases in this study. A male, 26 years old, complained about pain in his left hip one year ago. From a biopsy, we found an immunophenotype that is relevant to aneurysmal bone cysts with cystic spaces and stromal giant cells. Therefore, we diagnosed the patient with Aneurysm Bone Cyst Trochanter Left Femur. Secondly, a patient 22-year-old male has complained of pain in the left foot for six months. We got only red blood cells with lymphocytic inflammatory cells and without malignant cells from an open biopsy. We diagnosed patients with an aneurysmal bone cyst on the left calcaneus bone. All patients were treated with methylprednisolone on their lesion twice. All of the tumours subsided during follow-up and significant pain reduction
