[Brodie's abscess].

Brodie's abscess is a localized subacute or chronic osteomyelitis independent of any known previous acute infection. The entity is often mistaken for a bone tumour. The diagnosis requires biopsy. The treatment is curettage, drainage and antibiotics for a minimum of six weeks. We describe the characteristics of Brodie's abscess and describe a patient with an illustrating history, but with an unusual localization of the abscess (osilium).
