Choroid plexitis

Choroid plexitis is a general term referring to an inflammatory process affecting the choroid plexus; it is usually due an infectious process. It is rarely seen as an isolated process and is commonly found in association with encephalitis, meningitis, or ventriculitis 1. The choroid plexus can also be a place of noninfectious inflammatory disorders, such as sarcoidosis, xanthogranulomas, and rheumatoid nodules 2.


The choroid plexus lies at the interface between the cerebrospinal fluid and the systemic circulation, its capillaries have a fenestrated epithelium that serves as a way through which infectious organisms may gain access to the CNS 1,2
