The cistern of lateral cerebral fossa, also known as the sylvian cistern, is a significant subarachnoid cistern located in the brain. It is situated in the lateral cerebral fossa, which is part of the cerebral cortex. This cistern is an important structure in the central nervous system as it contains cerebrospinal fluid (CSF) and provides a protective cushion for the brain.

Anatomy

The cistern of lateral cerebral fossa is located in the lateral sulcus, also known as the Sylvian fissure. It is bordered by the temporal lobe and the frontal lobe of the brain. The cistern is part of the larger subarachnoid space, which is the area between the arachnoid mater and the pia mater.

Function

The primary function of the cistern of lateral cerebral fossa is to act as a reservoir for cerebrospinal fluid. This fluid circulates around the brain and spinal cord, providing essential nutrients and removing waste products. The presence of CSF in the cistern also helps to absorb shock and protect the brain from injury.

Clinical significance

The cistern of lateral cerebral fossa can be involved in various neurological disorders. For example, subarachnoid hemorrhage can occur in this area, leading to increased intracranial pressure and potential damage to the brain. Imaging techniques such as MRI and CT scans are often used to assess the condition of the cistern and diagnose potential issues.
