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.

Lectin binding sites in the choroid plexus and choroid plexus papillomas
Neurosurgical Review, 1980The surface of the cells of the normal choroid plexus and of the plexus papillomas is coated by sialomucopolysaccharides, containing substances which are positively stained with the colloidal iron (Hale-) reaction. After pretreatment with neuraminidase sialic acid is removed rendering the membrane negative to the Hale reaction. Using FITC- or rhodamine-

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.

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.

A review is made of 234 cases of choroid plexus papillomas collected from the literature, to which 11 unpublished personal cases are added.The clinical features, plain roentgenographic findings of the skull, and the value of pneumography, cerebral angiography and gamma encephalography in establishing the diagnosis are discussed in detail.The majority ...

Tumors of the Choroid Plexus in Children
Neurosurgery, 1989Abstract Primary neoplasms of the choroid plexus in children are surgically treatable, and the encouraging results of surgical removal, even for carcinoma, justify an aggressive surgical approach, Forty cases operated on over a span of 45 years have been reviewed in detail, including a rereading of all microscopic slides.

The choroid plexus (CP) produces cerebrospinal fluid (CSF) and forms a portion of the physical structure of the CSF-blood barrier. More recently, the CP been implicated in other basic aspects of neural functioning, such as surveying the chemical and immunological status of the brain, detoxifying the brain, secreting a nutritive cocktail of polypeptides

Chondromatosis of the choroid plexus
Neurosurgery, 1990Abstract We report the case of a patient with successful total removal of a previously undescribed intracranial tumor arising in the right lateral ventricle (probably of metaplastic origin). The histopathological examination revealed benign chondromatosis of the choroid plexus.
