Intracranial and spinal lipoma

Intracranial lipoma is a benign formation that consists of adipose tissue. This pathology mainly develops asymptomatically. Lipomas (adipose), do not have a tendency to cancer transformation. Intracranial lipoma is always an innate formation and is not associated with neoplasia, but is a violation of embryogenesis with the formation of a pathological area of ​​adipose tissue deposition. The presence of lipoma often correlates with other malformations of the brain.

In the cavity of the skull, the lipoma has very typical locations.

  • Lipoma of the interhemispheric fissure

  • Fat deposits of the falx brain

  • Lipoma of the convectional surface

  • Pericalloust lipoma

  • Lipoma of the cerebello-pontine angle

  • Lipoma of the selly region

  • Lipoma of other localization

However, lipoma also occurs elsewhere in the central nervous system, for example, it is often localized in the region of the cauda equina
