Brodie abscess
Updates to Article Attributes
Body
was changed:
A Brodie abscess refers to an abscess related to focus of chronic osteomyelitis in a bone. Unfortunately, there is no reliable way radiographically to exclude a focus of osteomyelitis. It has a protean radiographic appearance and can occur at any location and in a patient of any age. It might or might not be expansile, have a sclerotic or nonsclerotic border, or have associated periostitis.
Demographics and clinical presentation
Typically these present in children, more frequently in boys.
Pathology
Organism
- S. aureus (most common); cultures often negative
Location
It has a predilection for ends (metaphysis) of tubular bones:
- proximal/distal tibial metaphysis (most common)
- carpal and tarsal bones
Rarely traversing the open growth plate; epiphysis (in children and infants)/
Radiographic features
Plain film
- lytic lesion often in an oval configuration that is oriented along the long axis of the bone
- surrounded by thick dense rim of reactive sclerosis that fades imperceptibly into surrounding bone
- lucent tortuous channel extending toward growth plate prior to physeal closure
(pathognomonic - periosteal new-bone formation
- +/- adjacent soft-tissue swelling
- may persist for many months
