Differential diagnoses for this patient included choroid plexus
papilloma, angiomatous meningioma, and ganglioglioma.
In the present study, the diagnosis was incorrectly made for five cases of gliomas, where two cases of Grade III Astrocytoma were wrongly diagnosed as cerebral abscess and Metastasis respectively, one case of Grade II astrocytoma was wrongly diagnosed as acute infarct, one case of Oligoastrocytoma was wrongly diagnosed as Meningioma, one case of GBM was wrongly diagnosed as Choroid plexus

carcinoma is associated with germline mutations in TP53.
The study also shows that signals secreted by the choroid plexus
dynamically change during aging which affects aged stem cell behavior.
An interesting feature during this study was the constant immunolabelling of SVA within epithelial cells ol the choroid plexus
of the brain and the surrounding endothelia of blood vessels in piglets with neurologic disease On the basis of the IHC results and molecular findings h different tissues of the brain, we theorized that the neurologic manifestations of SVA observed during this investigation might be due to early infection of the choroid plexus
through alteration of the integrity of the vascular epithelium and subsequent dissemination to the adjacem neuropil.
Faivre, in 1854 and Luschka, in 1855 were the first researchers to suggest that the choroid plexus
is the source of CSF (3,29).
Occasionally, CSF overproduction may occur as the result of choroid plexus
(CP) cyst was defined as cyst greater than 1mm in diameter.
There are reports in the literature of successful management of hydrocephalus in these patients with ETV combined with choroid plexus
cauterisation, particularly in the Third World setting, where reliable access to follow-up for VPS and management of the possible complications may not exist.
The new cell lines show the potential to become cartilage and bone as well as brain-associated cells such as membranes surrounding the brain called meninges and choroid plexus
(the structure in the brain that creates cerebrospinal fluid).
LCT's NTCELL implant is injected directly into areas of the brain where the neurons have died off, introducing new choroid plexus
cells, the same 'support' cell that exist naturally in the brain.
Yan was diagnosed with a brain tumor called choroid plexus
carcinoma in August 2008 when he was 6 months old.
The organoid grew structures similar to a human brain's hippocampus, retina and choroid plexus
, which produces cerebrospinal fluid in the brain.
After 20 -- 30 days, defined brain regions, including a cerebral cortex, retina, meninges as well as choroid plexus
