Most frequent causative organism is Staphylococcus aureus.

[edit] Clinical Presentation
Localized pain, often nocturnal, alleviated by aspirin. Often mimics the symptoms of Osteoid osteoma, which is typically < 1cm diameter.
[edit] Most Frequent Sites
Usually occurs at the metaphysis of long bones. Distal tibia, proximal tibia, distal femur, proximal or distal fibula, and distal radius.
[edit] Radiographic Features
Oval, elliptical, or serpiginous radiolucency usually >1cm surrounded by a heavily reactive sclerosis, granulation tissue, and a nidus often less than 1cm. The margins often appear scalloped on radiograph. Brodie's abscess is best visualized using Computed tomography (CT) scan. Associated atrophy of soft tissue near the site of infection and shortening of the affected bone. Osteoblastoma may be a classic sign for Brodie's abscess.
[edit] History
Brodie abscess is named after Sir Benjamin Collins Brodie, 1st Baronet
[edit] Treatment
Mainly surgical approach has to be taken. If cavity is small then surgical evacuation & curettage is performed under antibiotic cover. If cavity is large then after evacuation, packing with cancellous bone chips
