Abstract:
Two cases of neurosarcoidosis studied by Gd-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging are reported. Both patients demonstrated multifocal white matter abnormalities that were clustered near regions of intense meningeal enhancement. Presumed spread of neurosarcoidosis along Virchow-Robin spaces was demonstrated, as evidenced by contrast enhancement along the course of vessels supplying some of the white matter abnormalities.
Insights
Two neurosarcoidosis cases revealed white matter abnormalities near meningeal enhancement. Gadolinium-enhanced MRI suggests spread along Virchow-Robin spaces via blood vessels.
Area of Science:
- Neurology
- Radiology
- Immunology
Background:
- Neurosarcoidosis is a rare granulomatous inflammatory disease affecting the central nervous system.
- Magnetic resonance imaging (MRI) is crucial for diagnosing and monitoring neurosarcoidosis.
Observation:
- Two patients with neurosarcoidosis underwent Gd-diethylenetriamine pentaacetic acid (Gd-DTPA)-enhanced MRI.
- Both patients presented with multifocal white matter abnormalities.
Findings:
- White matter lesions were clustered near areas of intense meningeal enhancement.
- Contrast enhancement along perivascular spaces (Virchow-Robin spaces) suggested disease spread along these pathways.
Implications:
- This imaging pattern supports the hypothesis of neurosarcoidosis dissemination along perivascular spaces.
- Enhanced MRI provides valuable insights into the pathophysiology and distribution of neurosarcoidosis.
