Diffusion-weighted MRI reveals choroid plexus cysts often appear hyperintense, suggesting proteinaceous content. These incidental findings have diffusion characteristics between CSF and white matter.

Area of Science:

  • Neuroradiology
  • Neuroimaging

Background:

  • Choroid plexus cysts are common incidental findings.
  • Their imaging characteristics, particularly on diffusion-weighted imaging (DWI), require further elucidation.

Purpose of the Study:

  • To characterize the DWI appearance of choroid plexus cysts.
  • To correlate DWI findings with pathological content.

Main Methods:

  • Retrospective review of DWI and contrast-enhanced T1-weighted MRI scans.
  • Analysis of signal intensity and apparent diffusion coefficient (ADC) values in 57 patients with choroid plexus cysts.
  • Pathological correlation in one case.

Main Results:

  • 95 cysts were analyzed; 78 showed homogeneous high signal intensity on DWI.

  • Focal high signal areas were seen in 12 cysts; 5 had no high signal.
  • The ADC of high signal areas was 1.46±0.14 x10⁻³ mm²/s, intermediate between CSF and white matter.

    • Conclusions:

    • DWI can help characterize choroid plexus cysts.
    • High signal intensity on DWI suggests proteinaceous or gelatinous content, as confirmed pathologically.
