Brodie abscess
A Brodie abscess is a rare type of subacute osteomyelitis (bone infection) that typically affects the long bones, most commonly the tibia (shin bone) or femur (thigh bone), though it can also involve other bones, including the foot. It is characterized by the formation of a localized bone abscess, which is a collection of pus that forms within the bone due to infection.
The abscess is generally caused by bacterial infection, often Staphylococcus aureus, but other bacteria like Streptococcus can also be involved. The bacteria can reach the bone via the bloodstream (hematogenous spread) or through direct contamination from trauma or surgery. It may also develop following a bone fracture or a previous infection elsewhere in the body.
Symptoms of Brodie abscess
- Pain that’s typically localized and can be aching or sharp, usually worsened with weight-bearing or pressure on the affected area.
- Tenderness in the area over the bone.
- Swelling might be present but is usually not as pronounced as in more acute forms of osteomyelitis.
- Fever might or might not be present, which is why the condition can sometimes be missed.
When a Brodie abscess affects the bones of the foot, it can cause pain and swelling, but the symptoms can be subtle. It may be harder to identify due to the complexity of the foot’s structure. Foot bones most commonly affected include the metatarsals or phalanges and the condition can lead to difficulty walking or pain during weight-bearing activities.
Diagnosis
- Physical examination. A healthcare provider will assess the tenderness, swelling and overall pain in the affected area.
- Imaging. X-rays are typically the first step in identifying Brodie abscesses, but they can be tricky to interpret. A CT scan or MRI is usually more definitive and can show a well-defined area of bone destruction or an abscess cavity.
- Bone biopsy. In certain cases, a sample of the infected bone may be taken to identify the specific bacteria responsible for the infection.
- Blood tests. Blood tests can sometimes show elevated levels of inflammation (like C-reactive protein or ESR), but these are not always conclusive for Brodie abscess.
