Brodie\'s abscess of the tarsal cuboid is a relatively rare presentation of this disease. In this study, we present the case of a 20-year-old male with post-traumatic Brodie\'s abscess of the tarsal cuboid that was left untreated for three years after the traumatic episode (penetrating injury with a sharp piece of wood). The patient presented pain over the injured area, limping, while plain foot radiographs showed a small lytic cavitary area in the cuboid. The magnetic resonance imaging revealed the presence of the abscess in a 2-cm diameter cavity in the cuboid bone and chronic inflammation of the surrounding plantar musculature. The treatment regime included curettage of the cavity, debridement of the inflammatory tissues, and administration of antibiotics, according to the cultures harvested intraoperatively, for six weeks. During this period, symptoms completely resolved.

Tuberculosis (TB) is a pulmonary disease with potential extrapulmonary manifestations that is caused by the bacteria Mycobacterium tuberculosis. Despite advancements in treatment, TB remains a worldwide public health concern. TB osteomyelitis accounts for approximately 3-5% of all extrapulmonary TB cases. We present a case of humeral TB osteomyelitis in a 22-month-old female with no pulmonary or systemic symptoms. This case offers insight into the diagnosis and management of TB osteomyelitis. A 22-month-old previously healthy Haitian-American female presented with a one-month history of a palpable mass over the anterolateral aspect of the proximal humerus without overlying erythema or soft tissue swelling. No additional symptoms were reported. She had no recent sick contacts but had visited Haiti during her infancy. Right proximal humerus X-ray and subsequent MRI revealed proximal humeral osteomyelitis with an intraosseous Brodie\'s abscess. Incision and drainage extracted caseous material, which tested positive for Mycobacterium tuberculosis via a polymerase chain reaction. The diagnosis was confirmed via positive QuantiFERON-TB Gold and purified protein derivative testing. The patient was treated with levofloxacin, isoniazid, pyrazinamide, pyridoxine, and rifampin during the hospitalization. Following discharge, she was continued on her antibiotic regimen and managed by the Florida Department of Health. Post-discharge, X-rays at three and twelve months showed evidence of lesion healing. TB osteomyelitis is a rare manifestation of TB infection, which may present insidiously without systemic or pulmonary symptoms. As timely treatment is vital to preventing complications, bone masses of unknown etiology should be investigated for TB infection, even without additional symptoms.

BACKGROUND: Septic osteomyelitis is a hematogenous bacterial bone infection. The acute presentation is the most common; the subacute one is less frequent. The aim of our case report is to put forward the features of this uncommon presentation and to propose a therapeutic management.
METHODS: We report a rare case of subacute osteomyelitis associated with Brodie\'s abscess of the tibial diaphysis in a four-year-old child. The chief complaint was a pain in the left tibia evolving for five weeks. The radiological findings and the unusual location of this pathology suggested a malignant bone tumor. Thanks to imaging assessment and bone biopsy the diagnosis of subacute osteomyelitis associated with Brodie\'s abscess was made. Therefore, the child had antibiotic therapy and plaster immobilization to avoid pathological fracture. Pain relief and radiological improvement was obtained after 3 months of antibiotic treatment. At a two-year follow-up, the X-ray was normal.
CONCLUSIONS: We report an uncommon case of subacute osteomyelitis which evolved to Brodie\'s abscess with diaphyseal location. The mainstream treatment is surgery combined with antibiotics. However, medical treatment alone can lead to recovery without sequelae.
CONCLUSIONS: Because of the atypical location and presentation of subacute osteomyelitis, the other differential diagnoses, especially malignant bone tumors have to be eliminated. In some cases, treatment may be based on antibiotics therapy alone.

Atraumatic limb pain in a child raises concerns in a medical setting. That is how a typical case of Brodie\'s abscess presents, having pain without any other symptoms of systemic illness. Assessment and investigations might also not reveal anything significant unless adequate imaging is done. Although Brodie\'s abscess has a very low rate of complications and morbidity/disability, it is important that such a presentation is assessed clinically with a diagnosis of Brodie\'s abscess in mind to ensure an uneventful and good outcome. We illustrate in this case report a similar presentation of an 11-year-old girl who had multiple visits to primary care. She was then assessed through radiological imaging. By the time of her diagnosis, her abscess had protruded through the skin. Thankfully management was done swiftly after identification and the final outcome was good with complete recovery.

Brodie\'s abscess is a relatively rare subacute form of osteomyelitis. Early diagnosis is challenging because of its insidious onset and vague symptoms. Magnetic resonance imaging is helpful in the diagnosis of Brodie\'s abscess; however, to date, no study has described the imaging findings of this disease in the early stage. Here, we present the case of a 14 year-old boy with Brodie\'s abscess in the proximal tibia. The lesion initially presented as a bone marrow edema in the proximal metaphysis of the left tibia on MRI and was misinterpreted as a bone bruise. Further radiological examination was performed 1 month later; this revealed the formation of an abscess cavity, which suggested Brodie\'s abscess. The patient was referred to our hospital and underwent curettage and debridement, which led to the definitive diagnosis of Brodie\'s abscess on histopathological findings and bacterial culture. On careful retrospective evaluation, the initial radiological findings suggested a microabscess on the metaphyseal side of the growth plate and bone marrow edema spreading from the lesion to the epiphysis. These radiological changes could be reliable evidence proving that the metaphyseal side of the growth plate is the origin of Brodie\'s abscess. Moreover, bone marrow edema with suspected microabscess in the metaphysis of the long bones can be the initial stage of the formation of Brodie\'s abscess and should be carefully followed up.

Distal radius fractures are among the most common pediatric fractures. In unstable fractures, treatment methods include closed or open reduction and percutaneous pinning with Kirschner wire (K-wire). This report presents a 13-year-old boy with an unstable distal radius and ulnar fractures, following an accident, who was treated with open reduction and K-wire fixation. He had pain and limited wrist range of motion for 6 months. Conventional radiography revealed a lytic lesion with evident sclerotic margin. Chronic osteomyelitis and Brodie\'s abscess were also indicated. A complete curettage and antibiotic therapy for 3 months was successful. Culturing results showed that Staphylococcus aureus and pathologic findings were in favor of chronic osteomyelitis. Subacute osteomyelitis and Brodie\'s abscess are rare retarded complications in percutaneous pinning of distal radius pediatric fractures. The curettage of the lesion and antibiotic therapy for at least 3 months would be successful and could result in good prognosis among children.

We report a rare case of Brodie\'s abscess caused by Mycobacterium kansasii (M. kansasii). Our patient is a 39-year-old male who presented with right foot pain a month after a new diagnosis of HIV infection. X-ray and MRI were done, and the diagnosis of Brodie\'s abscess was confirmed. Surgical debridement was done, and bone cultures grew M. kansasii after five weeks. Brodie\'s abscess is a subacute form of osteomyelitis usually caused by Staphylococcus. Some other bacteria have been implicated in several case reports. To best of our knowledge, this is the first case of Brodie\'s abscess caused by M. kansasii. M. kansasii is the atypical mycobacteria causing infections in immunocompromised hosts as in HIV patients with low CD4 count. M. kansasii is usually associated with lung infections with rare extrapulmonary manifestations as in our case.

Atraumatic limb pain and limp is a common pediatric presentation in the emergency department in the United States. In a majority of cases, these presentations are benign. However, in cases where pediatric patients are repeatedly presenting for atraumatic limb pain, further investigation is required. We present such the case of a 14-year-old female with acute worsening of progressive atraumatic knee pain who was found to have a Brodie\'s abscess, a subacute pyogenic form of osteomyelitis. This is a particularly challenging diagnosis, as it often presents with no associated symptoms such as fever or weight loss. The consequences of missing this diagnosis include permanent disability and potential amputation, but excellent outcomes can be expected for those who undergo timely surgical debridement and irrigation. We discuss the etiology, common presentations, and treatment of this rare but potentially limb-threatening disease in the hope that clinicians will consider this diagnosis in cases of persistent or progressive atraumatic limb pain.

Brodie\'s abscess is a rare form of subacute osteomyelitis, most commonly found in children between the ages of two to fifteen years. It has slight preponderance for males. It is characterised by centrally placed, well-circumscribed abscess within the medulla or metaphysis of long bone, most commonly tibia, surrounded by a sclerotic wall. It is sometimes considered a transitional phase for the development of chronic osteomyelitis due to infection persisting between two to six months without showing any systemic symptoms specific to osteomyelitis. It is assumed that it is clinically quiescent due to its intraosseous location. It rarely presents with overt symptoms, which occurs if either the abscess enlarges to create pressure against the periosteum, or if the purulent material extrudes from the confines from its sclerotic walls. Due to subliminal clinical features and indolent clinical course, radiologic investigations are the diagnostic modality of choice. Diagnosis requires a high degree of suspicion, especially in the scenario of sepsis with an unknown source of infection. We describe a case of Brodie\'s abscess in a sickle-cell disease patient which presented as episodes of vaso-occlusive crisis repeatedly before it was diagnosed along with a review of the literature.

Introduction: Brodie\'s abscess is a form of osteomyelitis. Since its first appearance in the medical literature in 1832, numerous cases have been described. The aim of this article is to provide the first comprehensive overview of published cases of Brodie\'s abscess, and to describe diagnostic methods, therapeutic consequences and outcomes. Methods: According to PRISMA guidelines a systematic review of the literature was performed. All published data in English or Dutch were considered for inclusion with no limitations on publication date. Data was extracted on demography, duration of symptoms, signs of inflammation, diagnostic imaging, causative agent, treatment and follow-up. Results: A total of 70 articles were included, reporting on a total of 407 patients, mostly young (median age 17) males (male:female ratio 2.1:1). The median duration of symptoms before diagnosis was 12 weeks (SD 26). Mostly consisting of pain (98%) and/or swelling (53%). 84% of all patients were afebrile, and less than 50% had elevated serum inflammation markers. Diagnosis was made with a combination of imaging modalities: plain X-ray in 96%, MRI (16%) and CT-scan (8%). Treatment consisted of surgery in 94% of the cases, in conjunction with long term antibiotics in 77%. Staphylococcus aureus was the pathogen most often found in the culture (67,3%). Outcome was generally reported as favorable. Recurrence was reported in 15,6% of the cases requiring further intervention. Two cases developed permanent disability. Conclusion: Brodie\'s abscess has an insidious onset as systemic inflammatory signs and symptoms were often not found. Treatment consisted mostly of surgery followed by antibiotics (77%) or only surgery (17%) and outcomes were generally reported as favourable.
