Choroid plexus of lateral ventricle

Plexus chorioideus ventriculi lateralis

  • Latin synonym: Plexus choroideus ventriculi lateralis

Definition

Choroid plexus of lateral ventricle is created when the tela choroidea in the roof of the third ventricle extends laterally through the choroid fissure and passes through the interventricular foramen of Monroe. This allows entry into the lateral ventricles on both sides. The choroid plexus of lateral ventricle is mainly located in the body and atrium of the ventricle, with none found in the anterior horn.

Additionally, the tela choroidea extends into the temporal horn of the lateral ventricle by intruding into the ventricular cavity through the lower part of the choroid fissure. This area lies between the stria terminalis and the fimbria of hippocampus, contributing to the formation of the choroid plexus in the temporal horn of lateral ventricle.
