“…36 Choroid plexus cysts can be located anywhere along the choroid plexus, although they are far more frequent in the supratentorial compartment. 37,38 Largely asymptomatic, they are rare in surgical samples. The cyst is lined by cuboidal to flattened epithelium resting on a fibrocollagenous wall and is immunoreactive for vimentin, transthyretin, S-100 protein, and cytokeratin.…”

Nonneoplastic and noninfective cysts of the central nervous system: A histopathological study

Nonneoplastic epithelial cysts involving the central nervous system are diverse and are predominantly developmental in origin. This study represents a surgical series describing the histopathological features of 507 such epithelial cysts with clinical and imaging correlation. Age at surgery ranged from 7 months to 72 years (mean: 33 years) affecting 246 male and 261 female patients. Colloid cyst was the most frequently resected cyst, followed by epidermoid cyst, arachnoid cyst, Rathke cleft cyst, dermoid cyst, neurenteric cyst, Tarlov cyst, and choroid plexus cyst. Diagnosis was based on the location of the cysts and the nature of the lining epithelium. Rathke cleft cyst showed the highest propensity for squamous metaplasia, significant inflammation, and xanthogranulomatous reaction. Ulceration of lining epithelium and calcification were most frequent in dermoid cyst. Radiopathological concordance was maximal for colloid cyst, followed by epidermoid and arachnoid cysts. Epidermoid and dermoid cysts exhibited the highest propensity for local tumor progression, followed by Rathke cleft cyst.

Background.Although choroid plexus cysts are a frequent incidental neuroimaging nding, symptomatic ones are rare -series of more than ve cases are hard to nd. In the absence of high-volume studies, there are no generally accepted algorithms for diagnosis and treatment for this pathology. Proposed surgical techniques include microsurgical excision or fenestration and endoscopic excision or fenestration with or without additional shunting. No de nitive conclusions exist about the superiority of a certain technique. Here we introduce an illustrative case of a patient with a symptomatic choroid plexus cyst in the trigone of the lateral ventricle and a systematic review of 65 additional published cases with the aim of identifying epidemiological features, variants of localization of the cysts, their symptoms, persistence of concomitant obstructive hydrocephalus, and treatment modalities. Materials and methods.A PRISMA-based literature search was performed on the PubMed, MEDLINE, Scopus, and Web of Knowledge databases. We include in the review case reports and case series of symptomatic choroid plexus cysts with full-texts or valuable abstracts available online in English and published by April 2023. All abstracts of retrieved studies were assessed by two independent researchers to avoid bias. Only descriptive statistics were used for the presentation of the results. Results.48 studies (39 case reports and 9 case series) with 65 depicted cases met the eligibility criteria. The review showed a slight predominance of choroid plexus cysts in men. The most common localizations of cysts were the trigone and the body of the lateral ventricle. Obstructive hydrocephalus is often present in patients with choroid plexus cysts. The most common symptoms of cysts were signs of increased ICP: headaches and vomiting. The main treatment approaches for symptomatic choroid plexus cysts were microsurgical excision, microsurgical fenestration, endoscopic fenestration, and total endoscopic excision. The tendency has been noted to shift from microsurgical to endoscopic procedures over the past two decades. Some data on the classi cation of cysts of the central nervous system and the underlying mechanisms of the pathogenesis of choroid plexus cysts are also presented. Conclusion.Although symptomatic cases of choroid plexus cysts are rare, by summarizing currently available data, one could clarify their common features and identify a preferable treatment modality.to perform a systematic review based on case reports and case series [34,45] in order to determine epidemiological features, localization, symptoms, persistence of concomitant obstructive hydrocephalus, and treatment modalities for symptomatic CPCs.

Background. Although choroid plexus cysts are a frequent incidental neuroimaging finding, symptomatic ones are rare – series of more than five cases are hard to find. In the absence of high-volume studies, there are no generally accepted algorithms for diagnosis and treatment for this pathology. Proposed surgical techniques include microsurgical excision or fenestration and endoscopic excision or fenestration with or without additional shunting. No definitive conclusions exist about the superiority of a certain technique. Here we introduce an illustrative case of a patient with a symptomatic choroid plexus cyst in the trigone of the lateral ventricle and a systematic review of 65 additional published cases with the aim of identifying epidemiological features, variants of localization of the cysts, their symptoms, persistence of concomitant obstructive hydrocephalus, and treatment modalities.
