Isolated choroid plexus lipomas are rare brain tumors. Magnetic resonance imaging (MRI) detected these lipomas more frequently than computed tomography (CT) scans, especially smaller lesions.

Area of Science:

  • Neuroradiology
  • Neuro-oncology
  • Medical imaging

Background:

  • Choroid plexus lipomas are rare, benign tumors.
  • Accurate diagnosis relies on advanced imaging techniques.

Purpose of the Study:

  • To determine the frequency and imaging characteristics of isolated choroid plexus lipomas.
  • Compare the detection rates of CT and MRI for these lesions.

Main Methods:

  • Retrospective analysis of 5351 CT and 1542 MRI brain examinations.
  • Evaluation of lesion characteristics, including size, location, and MRI signal intensities.
  • Calculation of lesion frequency based on imaging modality.

Main Results:

  • Seven cases of isolated choroid plexus lipomas were identified.

  • MRI detected lipomas with a frequency of 0.45%, while CT showed 0.04%.
  • Smaller lesions (<1 cm) were often missed by CT but visualized on MRI.

    • Conclusions:

    • Isolated choroid plexus lipomas are infrequently detected.
    • MRI is superior to CT for identifying smaller choroid plexus lipomas due to its sensitivity to fat content.
