Multiple sclerosis (MS) can mimic brain tumors on CT scans, leading to misdiagnosis. Magnetic resonance (MR) imaging is crucial for accurately diagnosing MS when CT findings are ambiguous.

Area of Science:

  • Neurology
  • Radiology
  • Neuroimaging

Background:

  • Multiple sclerosis (MS) is a chronic neurological disease.
  • Brain imaging is essential for diagnosing and monitoring MS.
  • CT scans can sometimes present findings similar to brain tumors.

Observation:

  • A case study of a 44-year-old woman with MS presenting with initial CT findings suggestive of a brain tumor.
  • Initial CT revealed a heterogeneously enhancing mass with edema, biopsy showed non-specific changes.
  • Subsequent CT scans showed lesion reduction, but new lesions appeared, necessitating further investigation.

Findings:

  • CT scans can exhibit features mimicking brain tumors in some MS patients.
  • Magnetic resonance (MR) imaging identified additional lesions not visible on CT.

  • MR imaging offers superior sensitivity in detecting MS-related brain lesions compared to CT.

    • Implications:

    • Accurate differentiation between MS and brain tumors is critical for appropriate patient management.
    • MR imaging should be considered the preferred modality for diagnosing suspected MS brain lesions.
    • This case highlights the importance of advanced neuroimaging in complex neurological presentations.
