Choroid Plexus Cyst

AbstractChoroid plexus cysts consist of abnormal folds of the choroid plexus that typically resolve prior to birth. Rarely, these cysts persist and may cause outflow obstruction of cerebrospinal fluid. We present a 5-month-old male born term who presented with lethargy, vomiting, and a bulging anterior fontanelle. Magnetic resonance imaging showed one large choroid plexus cyst had migrated from the right lateral ventricle through the third ventricle and cerebral aqueduct into the fourth ventricle causing outflow obstruction. The cyst was attached to the lateral ventricle choroid plexus by a pedicle. The cyst was endoscopically retrieved from the fourth ventricle intact and then fenestrated and coagulated along with several other smaller cysts. Histologic examination confirmed the mass was a choroid plexus cyst. The patient did well after surgery and did not require any cerebrospinal fluid diversion. Nine months after surgery, the patient continued to thrive with no neurological deficits. This case is the first we have found in the literature of a lateral ventricular choroid plexus cyst migrating into the fourth ventricle and the youngest of any migrating choroid plexus cyst. Only three other cases of a migrating choroid plexus cyst have been documented and those only migrated into the third ventricle. New imaging advances are making these cysts easier to identify, but may still be missed on routine sequences. High clinical suspicion for these cysts is necessary for correct treatment of this possible cause of hydrocephalus.

Choroid Plexus Cyst

Several types of mass lesions may occur in the third and lateral ventricles. Typically they arise from the lining of the ventricular cavity or from contiguous structures, by extension into the ventricle. The authors describe two patients, each of whom presented with a different rare lesion of the ventricular system. The first was a 53-year-old woman with a history of hypertension who sustained a blunt traumatic injury to the occipital region and subsequently developed a progressively worsening right-sided headache. Radiological examinations over the next 2 years revealed an enlarged right lateral ventricle and, ultimately, a choroid plexus cyst in its anterior and middle third, near the foramen of Monro, which is a rare location for these lesions. The cyst was removed en bloc, and follow-up examinations showed a significant improvement in her headache and a minimal differences in size between right and left ventricles. The authors also describe a 57-year-old man with hypertension, diabetes mellitus, and an old mycardial infarct, who presented to an outside institution with a progressively worsening headache, generalized malaise, and loss of olfactory sensation. Diagnostic imaging revealed a 1.5-cm oval lesion centered in the lamina terminalis region, an open craniotomy was performed, and evaluation of a biopsy sample demonstrated the mass to be a chordoid glioma of the third ventricle, a recently described glioma subtype. Two days after surgery, he suffered a left parietal stroke and an anterior mycardial infarction. After convalescing, he presented to The University of Texas M. D. Anderson Cancer Center for radiotherapy and follow up; 7 months later he was readmitted complaining of headache, short-term memory loss, and worsening confusion and disorientation. Neuroimaging revealed progression of the tumor (now 2 cm in diameter), which was removed by gross-total resection. His headache resolved immediately, and 2 months later his only complaint was of episodes of confusion. Three weeks later he died of a massive myocardial infarction. These two patients represent the sixth case of an adult with a choroid plexus cyst in the anterior lateral ventricle and the 19th case of an adult with a chordoid glioma of the third ventricle, respectively.

✓ A 10-year-old boy presented with acute obstructive hydrocephalus caused by the impaction of a calculus on the cerebral aqueduct. The calculus migrated from the third ventricle to the fourth ventricle after ventricular drainage and right ventriculoperitoneal shunt placement had been performed. The nature and origin of the calculus could not be determined, although its release from the choroid plexus in the lateral ventricle is highly possible.

AbstractBACKGROUNDDuring surgery in the posterior fossa in the prone position, blood can sometimes fill the surgical field, due both to the less efficient venous drainage compared to the sitting position and the horizontally positioned surgical field itself. In some cases, blood clots can wedge into the cerebral aqueduct and the third ventricle, and potentially cause acute hydrocephalus during the postoperative course.OBJECTIVETo illustrate a technique that can be used in these cases: the use of a flexible scope introduced through the opened roof of the fourth ventricle with a freehand technique allows the navigation of the fourth ventricle, the cerebral aqueduct, and the third ventricle in order to explore the cerebrospinal fluid pathways and eventually aspirate blood clots and surgical debris.METHODSWe report on one patient affected by an ependymoma of the fourth ventricle, for whom we used a flexible neuroendoscope to explore and clear blood clots from the cerebral aqueduct and the third ventricle after the resection of the tumor in the prone position. Blood is aspirated with a syringe using the working channel of the scope as a sucker.RESULTSA large blood clot that was lying on the roof of the third ventricle was aspirated, setting the ventricle completely free. Other clots were aspirated from the right foramen of Monro and from the optic recess.CONCLUSIONWe describe this novel technique, which represents a safe and efficient way to clear the surgical field at the end of posterior fossa surgery in the prone position. The unusual endoscopic visual perspective and instrument maneuvers are easily handled with proper neuroendoscopic training.

Abstract BACKGROUND AND IMPORTANCE: Arachnoid cysts within the fourth ventricle have rarely been reported in the literature. Different procedures have been performed to restore a normal cerebrospinal fluid dynamic or pressure, including shunting and partial or complete excision of the cyst by open microsurgery. Cerebrospinal fluid shunts give only partial improvement of symptoms and are prone to malfunctions. The microsurgical excision of the cyst seems to offer the best chance of success. CLINICAL PRESENTATION: We report the case of a fourth ventricle arachnoid cyst successfully treated with a complete endoscopic cerebral procedure via the third ventricle. CONCLUSION: Endoscopic fenestration of fourth ventricle arachnoid cysts may be considered an effective neurosurgical treatment.

ObjectiveTo investigate and compare occult damages in aquaporin-4 (AQP4)-rich periependymal regions in patients with neuromyelitis optica spectrum disorder (NMOSD) vs healthy controls (HCs) and patients with multiple sclerosis (MS) applying quantitative T1 mapping at 7 Tesla (T) in a cross-sectional study.MethodsEleven patients with NMOSD (median Expanded Disability Status Scale [EDSS] score 3.5, disease duration 9.3 years, age 43.7 years, and 11 female) seropositive for anti-AQP4 antibodies, 7 patients with MS (median EDSS score 1.5, disease duration 3.6, age 30.2 years, and 4 female), and 10 HCs underwent 7T MRI. The imaging protocol included T2*-weighted (w) imaging and an MP2RAGE sequence yielding 3D T1w images and quantitative T1 maps. We semiautomatically marked the lesion-free periependymal area around the cerebral aqueduct and the lateral, third, and fourth ventricles to finally measure and compare the T1 relaxation time within these areas.ResultsWe did not observe any differences in the T1 relaxation time between patients with NMOSD and HCs (all p > 0.05). Contrarily, the T1 relaxation time was longer in patients with MS vs patients with NMOSD (lateral ventricle p = 0.056, third ventricle p = 0.173, fourth ventricle p = 0.016, and cerebral aqueduct p = 0.048) and vs HCs (third ventricle p = 0.027, fourth ventricle p = 0.013, lateral ventricle p = 0.043, and cerebral aqueduct p = 0.005).ConclusionUnlike in MS, we did not observe subtle T1 changes in lesion-free periependymal regions in NMOSD, which supports the hypothesis of a rather focal than diffuse brain pathology in NMOSD.

Relevance Investigation of the cerebrospinal fluid system of children of different ages, especially pre-school and school periods of childhood, becomes essential, since the further development of the brain and its proper functioning depends on the way it functions. Considering the MRI indications of the elements of the cerebrospinal fluid system of children is important for the development of neurology and neurosurgery, it is necessary to consider gender differences in the brain size and structure.Objective To study the sex differences in the structure of the cerebrospinal fluid system in seven-year-old children.Material and Methods For the study, archival data on the sizes of the lateral ventricles of the brain of 120 children aged 7 (60 boys and 60 girls) were involved, in particular: 1) the length of the anterior horn; 2) the width of the anterior horn; 3) the length of the central part; 4) the width of the central part; 5) the length of the posterior horn; 6) the width of the posterior horn; 7) the length of the lower horn; 8) the anteroposterior size; 9) the distance between the anterior horns; 10) the distance between the posterior horns; 11) the length of the third ventricle; 12) the height of the third ventricle; 13) the length of the aqueduct; 14) the length of the fourth ventricle; 15) the height of the fourth ventricle. The studies were carried out using the method of magnetic resonance imaging. Quantitative indicators were assessed for compliance with the normal distribution using the KolmogorovSmirnov test. The accumulation, correction, systematization of the initial information were carried out in Microsoft Excel 2016. Statistical analysis was carried out using the Statistica 10.0 software (StatSoft Inc., USA). The results were considered statistically significant at p < 0.05.Results The data obtained in the study of the cerebrospinal fluid system in children during their pre-school period of childhood are indicators of the norm and can be used for diagnostic studies in the departments of radiation diagnostics. The bilateral asymmetry of the lateral ventricles of the brain in pre-school children, discovered during the work, is of crucial clinical significance. The morphometric indicators of the elements of the cerebrospinal fluid system should be considered by specialists in the study of brain neuroplasticity.Conclusion Analysis of the obtained in vivo encephalometric data indicates the presence of sexual variability of the brain and parameters of the structures of the cerebrospinal fluid.

ABSTRACT Two artificial cerebrospinal fluid mixtures, one having a higher than normal sodium, but lower than normal potassium content, the other having a lower than normal sodium, but higher than normal potassium content, were perfused alternately through the cerebral ventricular system of seven dogs, from the right lateral ventricle and down through the third ventricle, aqueduct and fourth ventricle. During this procedure blood was collected through the adrenal vein and the concentration of cortisol (11β, 17,12-trihydroxy-pregn-4-eme-3,20-dione), cortisone (17,21-dihydroxypregn-4-ene-3,11.20-trione), corticosterone (11β,21-dihydroxy-pregn-4-ene3,20-dione). compound S (11-dihydroxy-3,20-dioxo-pregn-4-en-18-al) and aldosterone (11β.21-dihydroxy-3,20-dioxo-pregn-4-en-18-al) determined. A gradual and marked increase in the secretion of all the cortical compounds was observed during the procedure. This pattern was not altered by changing from one of the artificial cerebrospinal fluid mixtures to the other.
