- Middle cerebral artery cistern
The Sylvian cistern, also known as the insular cistern, is the deep (cisternal) part of the Sylvian fissure, which may be considered one of the CSF-filled subarachnoid cisterns.
Gross anatomy
There are two paired cisterns on either side. It is the transitional area between the basal cisterns and the subarachnoid space 2.
Relations and/or Boundaries
The cistern is part of the Sylvian fissure 3. The anterior part sits between the fronto-orbital cortex and the temporal lobe. The posterior part borders the insular cortex and the medial surface of the operculum (fronto-parietal and temporal).
Medially, it communicates with the carotid cistern. Laterally, it becomes the superficial part of the Sylvian fissure.
