RESUMO
Aneurysmal bone cyst (ABC) is a very rare, benign, non-neoplastic lesion that typically occurs in the early life, usually before the 3rd decade, it's exceptional in younger than 10 years. We report the diagnosis and treatment of an 8 years old girl with an ABC in the left temporal bone, a very unusual location. Although the histologic characteristics have been well defined, its pathogenesis remains obscure and not totally explained. Total excision nowadays is the treatment of choice.
