Transport across the choroid plexus epithelium [PDF]
American Journal of Physiology - Cell Physiology, 2017 The choroid plexus epithelium is a secretory epithelium par excellence. However, this is perhaps not the most prominent reason for the massive interest in this modest-sized tissue residing inside the brain ventricles. Most likely, the dominant reason for

Papillomas of the Choroid Plexus
Journal of Neurosurgery, 1968p APILLOMAS of the choroid plexus are solitary reddish grey tumors attached to the choroid plexus. The irregular surface is covered by a thin transparent capsule, and the firm tumor occasionally is partly calcified. Microscopically, papillomas resemble normal choroid plexus, being composed of columnar or cuboidal epithelium supported by highly ...

T he brain is choosy about what it allows to enter its tissues. Because it can function only in a chemically stable environment, the brain shuts out most water-soluble substances in the blood-even some potentially helpful medications. Three structures stand as gatekeepers to the brain's interior: the network of cere bral capillaries, the arachnoid mem

Choroid plexus papillomas (CPPs) are rare neoplasms accounting for less than 1% of all intracranial tumours. We present our experience with 13 consecutive cases managed by us between 1981 and 1991. There were eight children and five adults. Five patients had tumours in the 4th ventricle, four in lateral ventricle, one in the 3rd ventricle, two in the ...

Xanthogranulomas of choroid plexus
Neuroradiology, 1987Computed tomographic features of xanthogranulomas of the choroid plexus are presented. The characteristic location of bilateral intense homogeneously enhanced masses with central lucencies is thought to be diagnostic of xanthogranuloma of the choroid plexus.

Development of the choroid plexus
Microscopy Research and Technique, 2000Mammalian choroid plexuses develop at four sites in the roof of the neural tube shortly after its closure, in the order IVth, lateral, and IIIrd ventricles. Bone morphogenetic proteins and tropomyosin are involved in early specification of these sites and in early plexus growth.

Choroid plexus tumors are rare intraventricular papillary neoplasms derived from choroid plexus epithelium, which account for only between 0.4-0.6% of all intracranial and 2-3% of pediatric neoplasms. Plexus papillomas outnumber choroid plexus carcinomas by a ratio of 5:1 and around 80% of choroid plexus carcinomas arise in children.

The senses of the choroid plexus
Progress in Neurobiology, 2019The composition of cerebrospinal and brain interstitial fluids is ensured by barriers between the blood and the brain parenchyma (the blood-brain barrier) and between the blood and the cerebrospinal fluid (the blood-cerebrospinal fluid barrier). Barrier function results from the combination of tight junctions between cells that impair solute flux via ...

Xanthogranuloma of the choroid plexus
American Journal of Roentgenology, 1984Uncommon tumefactions known as xanthogranulomas can occur throughout the body. Some appear to develop as benign or malignant neoplasms. An even less familiar xanthogranuloma occurs within the choroid plexus. Most are tiny plaques only a few millimeters in diameter. However, they can present as masses of significant size within the glomus.

The isolated choroid plexus cyst
Obstetrics & Gynecology, 1998To describe the karyotypes of a population of fetuses with choroid plexus cysts and compare affected fetuses with and without additional ultrasonographic findings.The study population included all patients undergoing second-trimester ultrasound examination in a prenatal diagnostic program between January 1993 and October 1995.
