Choroid plexus tumours

British Journal of Cancer, 2002
Choroid plexus tumours are rare epithelial brain tumours and limited information is available regarding their biology and the best treatment. A meta-analysis was done to determine prognostic factors and the influence of various treatment modalities.

Choroid plexus papilloma

Asian Journal of Neurosurgery, 2017
Choroid plexus tumors are rare intracranial tumors which account for only 0.4-0.6% of all brain tumors. These are intraventricular papillary neoplasms derived from choroid plexus epithelium and range from choroid plexus papillomas (World Health Organisation (WHO) grade I) to choroid plexus carcinomas (WHO grade III).

Psammoma bodies as signs of choroid plexus ageing: A morphometric analysis [PDF]

Vojnosanitetski Pregled, 2017
Background/Aim. Psammoma bodies (PB) are regarded as benign consequences of ageing in choroid plexus stroma. The aim of this study was to assess the morphometric characteristics of psammoma bodies of all four choroid plexuses during the ageing process ...

Method for Primary Epithelial Cell Culture from the Rat Choroid Plexus

Bio-Protocol, 2020
The choroid plexus consists of a network of secretory epithelial cells localized throughout the lateral, third and fourth ventricles of the brain. Cerebrospinal fluid (CSF) is generated by the choroid plexus and released into the ventricular environment.

Histological Evidence for the Enteric Nervous System and the Choroid Plexus as Alternative Routes of Neuroinvasion by SARS-CoV2

Frontiers in Neuroanatomy, 2020
Evidence is mounting that the novel corona virus SARS-CoV2 inflicts neurological symptoms in a subgroup of COVID-19 patients. While plenty of theories on the route of neuroinvasion have been proposed, little histological evidence has been presented ...

Choroid plexus in developmental and evolutionary perspective

Frontiers in Neuroscience, 2014
The blood-cerebrospinal fluid boundary is present at the level of epithelial cells of the choroid plexus. As one of the sources of the cerebrospinal fluid, the choroid plexus plays an important role during brain development and function.

Hypertensive nonobstructive hydrocephalus as main magnetic resonance imaging feature in a dog with disseminated choroid plexus carcinomatosis

Journal of Veterinary Internal Medicine, 2023
Obstructive or nonobstructive hypertensive hydrocephalus is reported in choroid plexus tumors. Choroid plexus tumors typically present as T2‐weighted hyperintense intraventricular masses with occasional cerebrospinal fluid‐drop metastasis.
