INTRODUCTION: Aneurysmal bone cyst (ABC) is a rare entity, accounting for less than 1% of all bone cyst diagnoses. Its etiology is still unclear, and several theories have been proposed. A proper diagnosis is mandatory cause it could be confused with similar lesions.
EVIDENCE ACQUISITION: The aim of this study is to analyze the distinctive features of ABC and the various treatment options discussed in literature. A search about ABC was performed on the most important databases. This article focuses on the various surgical treatments for ABC. Treatment choice is empirical and depends on the age of the patient and on the size and site of the lesion.
EVIDENCE SYNTHESIS: Curettage and excision with or without the use of bone graft/polymethylmethacrylate is the most frequent option. Various factors have been connected with a major risk of recurrence and treatment of recurrences and lesions of spine or deep in pelvis could really be a challenge for orthopedic surgeons. The article also evaluates other complementary treatment options, such as arterial embolization, percutaneous sclerotherapy, radiotherapy and curopsy.
CONCLUSIONS: There is currently no such thing as a unique treatment for aneurysmal bone cysts. Several treatment options have been proposed so far, and in selected cases, they should be used together.

KEY WORDS: Aneurysmal bone cysts - Operative surgical procedures - Therapeutic embolization - Sclerotherapy
