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 authors report a case of carcinoma of the choroid plexus and review the 22 cases reported since 1844 that adhere to the criteria for primary choroid plexus carcinoma. Two-thirds of the tumors are found in children and all of these are located in the lateral ventricles.

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.

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.

Choroid plexus tumors (CPTs) are rare, primary brain tumors arising from the neuroepithelium of the choroid plexus. Although they may be found in patients of any age, the vast majority occur in the pediatric population. Up to 70% of these neoplasms occur in children, with over half arising in children under 2 years of age [39]. The annual incidence for

Multiple Sclerosis Journal
The choroid plexus (CP), a highly vascularized structure within the ventricles of the brain, has come under increased scrutiny over the last several years as potentially having a role in the pathophysiology of multiple sclerosis (MS). Originally consider as being only responsible for the production of cerebrospinal fluid, it is now widely recognized ...

The choroid plexus has the highly specific function of producing cerebrospinal fluid (CSF). It is anatomically localized to the parenchymal/ventricular junction in all four ventricles. The choroid plexus is derived from the specialization of ventricular epithelium along certain segments of the neural tube, and there is a common ontogeny between choroid

This chapter presents the case of an 11-month-old male with a history of macrocephaly, anorexia, and right upper extremity tremors. His family history was significant for a father with anaplastic astrocytoma. Physical exam was notable for left asymmetric macrocephaly and a full/tense fontanelle.

Although rare, choroid plexus tumors are relatively common neoplasms of infancy, being papilloma more frequent than carcinoma. Highly cellular smears of epithelial appearance with papillae, small clusters, and single cells are characteristic findings.
