Magnetic resonance imaging of multiple brain abscesses of the bilateral basal ganglia
1Third Department of Internal Medicine, National Defense Medical College, Tokorozawa.
Abstract:
A 64-year-old woman developed multiple brain abscesses of the basal ganglia associated with Klebsiella pneumoniae septicemia. Magnetic resonance (MR) images showed three different stages of the brain abscesses. The images of early cerebritis of this site mimicked lacunar infarctions or dilated Virchow-Robin spaces. The differentiation of the brain abscess from lacunae and dilated Virchow-Robin spaces is discussed, together with the evolution of the brain abscesses on MR images.
Insights
This study details a case of Klebsiella pneumoniae septicemia causing multiple brain abscesses. Magnetic resonance imaging revealed distinct stages of cerebritis, highlighting differentiation challenges from other brain lesions.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Septicemia caused by Klebsiella pneumoniae can lead to serious central nervous system complications.
- Brain abscesses, particularly in the basal ganglia, require accurate and timely diagnosis.
- Distinguishing early brain abscesses from other pathologies is crucial for effective treatment.
Observation:
- A 64-year-old female patient presented with multiple basal ganglia brain abscesses secondary to Klebsiella pneumoniae septicemia.
- Serial Magnetic Resonance (MR) imaging demonstrated three distinct stages of abscess development.
- Early-stage cerebritis imaging findings mimicked lacunar infarctions and dilated Virchow-Robin spaces.
Findings:
- MR imaging characteristics of early cerebritis were analyzed for differential diagnosis.
- The study illustrates the evolution of brain abscesses on MR images.
- Key imaging features aiding in the differentiation between brain abscesses and lacunar infarctions/dilated Virchow-Robin spaces are discussed.
Implications:
- Improved understanding of MR imaging in diagnosing brain abscesses.
- Enhanced ability to differentiate brain abscesses from mimics, potentially leading to earlier intervention.
- Highlights the importance of considering septic emboli in patients with Klebsiella pneumoniae septicemia and neurological symptoms.
