Xanthogranulomas of the choroid plexus are discovered incidentally on autopsy in 1.6 to 7% of cases, and are typically found in the lateral ventricles. Very rarely, however, they can become symptomatic because of obstruction of the ventricular system, and these tend to be found in the third ventricle. There has only been one published case of fourth ventricle choroid plexus xanthogranuloma. We ...

The association of choroid plexus cysts with fetal aneuploidy, particularly trisomy 18, was first noted in 1986. Through the years there have been numerous reports on this subject, but no consensus has been reached with regard to chromosomal risk. In this review, we attempt to summarise published reports on second trimester choroid plexus cysts, with an emphasis on the strengths and weaknesses ...

Autosomal dominant polycystic kidney disease (ADPKD) is a genetic systemic disorder, which is associated with cyst formation in several organs, renal function decline and a higher prevalence of intracranial aneurysms. We report a 52-year-old, otherwise healthy, man with ADPKD who had asymptomatic, bilateral, multiple cysts in the choroid plexus, which is an extremely rare abnormality. Recent ev...

Choroid plexus carcinoma is a rare tumor representing less than 1% of all brain tumors. In adult, the incidence is extremely rare making the diagnosis difficult. Majority of choroid plexus tumor is found in the ventricle. However, ectopic sites such as intracranial extraventricular or spine have been reported. We report a case of choroid plexus carcinoma in a 39-year-old man. The clinical prese...

Lead (Pb) exposure reportedly modulates PKC activity in brain endothelial preparations, which may underlie Pb-induced damage at the blood-brain barrier. Our previous work indicates that Pb accumulates in the choroid plexus and causes dysfunction of this blood-cerebrospinal fluid (CSF) barrier. The present studies were undertaken to test the hypothesis that Pb in the choroid plexus may alter PKC...

Hydranencephaly is a rare congenital disease defined as an absence of cerebral hemispheres with an intact thalamus, brain stem, and cerebellum. Generally, patients with hydranencephaly require cerebro-spinal fluid diversion due to progressive hydrocephalus. An excellent view of the choroid plexus and advancement of the neurosurgical endoscope were possible, leading to easy coagulation of the ch...

Morphological alterations of choroid plexus in Alzheimer's disease (AD) have been extensively investigated. These changes include epithelial atrophy, thickening of the basement membrane, and stroma fibrosis. As a result, synthesis, secretory, and transportation functions are significantly altered resulting in decreased cerebrospinal fluid (CSF) turnover. Recent studies discuss the potential imp...

A 54-year-old female presented with a cryptic arteriovenous malformation (AVM) of the choroid plexus of the fourth ventricle causing intraventricular hemorrhage. Computed tomography and magnetic resonance imaging disclosed the lesion near the fourth ventricle, but bilateral vertebral angiograms showed no abnormalities. The preoperative diagnosis was cavernous angioma. The mass was removed compl...

(1) Background: Multiple sclerosis (MS) is an auto-immune, chronic, neuroinflammatory, demyelinating disease that affects mainly young patients. This progressive inflammatory process causes the chronic loss of brain tissue and results in a deterioration quality life. To monitor neuroinflammatory activity predict further development disease, it necessary to find suitable biomarker could easily b...

PEPT2 is functionally active and localized to the apical membrane of rat choroid plexus epithelial cells. However, little is known about the transport mechanisms of endogenous neuropeptides in choroid plexus, and the role of PEPT2 in this process. In the present study, we examined the uptake kinetics of carnosine in rat choroid plexus primary cell cultures and choroid plexus whole tissue from w...
