Choroid Plexus of Cerebral Hemisphere (Left) (Plexus choroideus ventriculi lateralis sinister)
Educational content only — not medical advice.
Anatomy
The choroid plexus of the left cerebral hemisphere is a highly vascular fringe of villous ependymal tissue projecting into the atrium and inferior horn of the left lateral ventricle. Formed by invaginated vascular pia mater (tela choroidea) covered by specialized cuboidal choroid epithelial cells, it actively synthesizes and secretes cerebrospinal fluid (CSF), regulates intracranial chemical homeostasis, and forms the blood-CSF barrier.
Clinical notes
Choroid plexus papillomas cause excessive CSF secretion and communicating hydrocephalus; calcification of the glomus chorioideum in the ventricular atrium is a normal age-related radiologic landmark.
