Sylvian cistern

The Sylvian cistern, also known as the insular cistern, is one of the CSF-filled subarachnoid cisterns.

Gross anatomy

There are two paired cisterns on either side. It is the transitional subarachnoid space between the rest of the basal cisterns and the Sylvian fissure (lateral sulcus) 2.

  • insular cortex (island of Reil)
  • opercular cortex: fronto-orbital, fronto-parietal and temporal

The cistern is intimately related to the sylvian fissure, insular cortex and the operculum.
