Huge Aneurysmal Bone Cyst of the Sacrum: A Case Report

ABSTRACT

We present a rare case of 22-year-old man who had a huge aneurysmal bone cyst of the sacrum. Preoperative adjuvant selective arterial embolization of the branches of internal iliac arteries was performed. The next day, the patient received a radical surgical excision and posterolateral screw fixation. The patient was discharged without neurological problems or symptoms. Currently, the patient has been treated without local recurrence and is symptom free. Overall, in similar cases, an aneurysmal bone cyst, chordoma, osteoblastoma and giant cell tumor should be included in a differential diag- nosis based on the imaging studies.
