Surgical Management of Aneurysmal Bone Cyst of the Pubis: A Case Report and Review of Literature

Abstract

Introduction: Aneurysmal bone cysts (ABC) are expansile, lytic, and benign but locally aggressive lesions. Pelvic ABCs are rare and sometimes difficult to manage surgically. Case Report: A 17-year-old female presented with progressive pain and swelling in the right inguinal region. Pelvis radiograph showed a lytic expansile lesion of the superior pubic ramus. A multiloculated cystic lesion was evident on magnetic resonance imaging, and postoperative histopathological evaluation confirmed the diagnosis of ABC. The patient was treated successfully with an intralesional curettage and bone grafting. The postoperative course was uncomplicated with complete healing and no recurrence after 14 months of follow-up. Conclusion: ABC of the pubic ramus is a rare entity. Complete intralesional curettage and bone grafting is an effective treatment for pubic ABC. An individualized management approach considering the surgical team expertise, tumor size, and proximity to neighboring structures is recommended..
