Lateral ventricles

Dr Jeremy Jones et al.

The lateral ventricles are a paired structure and part of the ventricular system in the brain. They are larger than the third or fourth ventricles, but can be asymmetrical, and each has three horns that project into the lobe after which they are named:

CSF is produced in the choroid plexus situated within the ventricles and exits along the interventricular foramen (of Monro) to the third ventricle. The central part of lateral ventricle is called the cella media. 

Related pathology

The volume of the lateral ventricles is known to increase with age due to the cerebral involution. They are also enlarged in a number of neurological conditions (e.g. schizophrenia and bipolar disorder) or be pathologically enlarged in hydrocephalus. ​
