[Multiple cerebral abscess caused by Nocardia brasilientis]
Abstract:
Streptococcus aureus, streptococci, and enterobacteria were major causative agents of abscesses of the brain. At present, associated infection is responsible for 60% of cerebral abscesses. When systemic and specific immunities are diminished, a risk for cerebral abscesses caused by fungi increases. Among them, there are the most common fungi Candida species or Aspergillus species. The paper gives an example of successful complex treatment of multiple cerebral abscesses caused by an association of Nocardia brasiliensis and Staphylococcus epidermidis. The specific feature of the observation was the correct diagnosis before intraoperative verification of cerebral abscesses. The disease developed in the presence of diminished systemic immunity and in the absence of specific immunity to Nocardia. Immunodeficiency could be caused by prior herpetic infection, Epstein-Barr disease, a wasp bite. The pathogen that was able to cause microstrokes played an indubitable role in the pathogenesis of the disease, which predisposed to the development of cerebral abscesses in patients with immunodeficiency. Impaired blood circulation in the occipital region could be also induced by wasp venom.
Insights
Cerebral abscesses are often caused by bacteria, but fungi can also be a risk, especially in immunocompromised individuals. This case highlights successful treatment of multiple brain abscesses caused by Nocardia brasiliensis and Staphylococcus epidermidis.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Bacterial infections (Streptococcus aureus, streptococci, enterobacteria) are primary causes of cerebral abscesses.
- Fungal infections (Candida, Aspergillus) pose an increased risk in patients with diminished systemic and specific immunity.
- Associated infections account for 60% of current cerebral abscess cases.
Observation:
- A case of multiple cerebral abscesses caused by Nocardia brasiliensis and Staphylococcus epidermidis is presented.
- The patient had diminished systemic immunity and lacked specific immunity to Nocardia.
- Potential contributing factors to immunodeficiency included prior herpetic infection, Epstein-Barr disease, and a wasp bite.
Findings:
- Successful complex treatment was achieved for the multiple cerebral abscesses.
- A key feature was accurate diagnosis prior to intraoperative verification.
- The identified pathogen's ability to cause microstrokes played a role in the disease's pathogenesis, predisposing to abscess formation in immunocompromised patients.
Implications:
- This case demonstrates the possibility of successful treatment for complex cerebral abscesses involving unusual pathogens.
- Highlights the importance of considering diverse etiological agents and predisposing factors, including environmental exposures like wasp venom, in cerebral abscess pathogenesis.
- Emphasizes the need for early and accurate diagnosis in managing cerebral abscesses, particularly in immunocompromised individuals.
