Pelvic Aneurysmal Bone Cyst in an Adolescent: A Case Report and Literature Review.

An aneurysmal bone cyst (ABC) is a benign but locally aggressive lesion. The challenge in managing pelvic ABC arises from its relative inaccessibility and the presence of nearby neurovascular structures. In this report, we present the case of a 14-year-old female with pelvic ABC and describe the symptoms, signs, and radiographic appearance of the ABC, management, and good outcome of non-surgical management by selective trans-arterial embolization. Although challenging, non-surgical management of pelvic ABCs can result in a favorable outcome. In addition, we reviewed the literature regarding the treatment modalities of pelvic ABCs.
