Pericallosal lipomas are rare benign tumors. T1-weighted sagittal MRI best visualizes their relationship to the corpus callosum, often showing them surrounding the splenium.

Area of Science:

  • Neuroradiology
  • Neuro-oncology
  • Neuroanatomy

Background:

  • Pericallosal lipomas are congenital tumors.
  • They are typically found along the corpus callosum.
  • Understanding their precise location is crucial for diagnosis and surgical planning.

Purpose of the Study:

  • To describe the anatomical relationship of pericallosal lipomas to the corpus callosum.
  • To evaluate the utility of T1-weighted sagittal MRI in characterizing these lesions.

Main Methods:

  • Retrospective review of six cases of pericallosal lipomas.
  • Analysis of magnetic resonance imaging (MRI) findings, focusing on T1-weighted sagittal sequences.

Main Results:

  • T1-weighted sagittal MRI effectively demonstrated the relationship between lipomas and the corpus callosum.

  • In four cases, lipomas surrounded the splenium.
  • In two cases, lipomas were located posterior and caudal to the splenium, with no exclusively dorsal localizations observed.

    • Conclusions:

    • T1-weighted sagittal MRI is optimal for visualizing pericallosal lipomas.
    • These tumors predominantly involve the splenium of the corpus callosum or adjacent posterior regions.
