Abstract
The cavum vergae cyst (CVC) is an uncommon brain malformation. Most patients with CVC are asymptomatic and do not require neurosurgical intervention. Separately, cerebral X-linked adrenoleukodystrophy (X-ALD) is one of the phenotypes of a genetic peroxisomal disorder that is seldom managed by neurosurgeons. We report an unusual case of cerebral X-ALD presenting as an enlarging CVC in a child, and discuss its nuances in corroboration with the literature. A previously well six-year-old male presented with confusion and fever. Urgent neuroimaging demonstrated a large CVC with resultant hydrocephalus. Of note, there were symmetrical areas of signal changes in the periventricular white matter bilaterally involving the corpus callosum, thalami, cerebral peduncles, midbrain, and pons in his MRI. Further investigations performed as part of his medical workup reported high plasma concentrations of very long-chain fatty acids (VLCFA). Put together, a diagnosis of cerebral X-ALD was confirmed. Initially, an external ventricular drain was inserted directly into the CVC under stereotaxy to decompress it. Subsequently, endoscopic fenestration of the CVC was performed as the definitive treatment. He recovered uneventfully from the neurosurgical interventions and proceeded for the treatment of his cerebral X-ALD. To our knowledge, this is the first report of cerebral X-ALD presenting as a CVC in a patient. This case adds to the limited literature for both rare conditions and highlights the importance of a multidisciplinary approach to management.

Abstract
Cavum septum pellucidum (CSP) and cavum vergae (CV) cysts are commonly found incidentally. They are usually asymptomatic but may present with symptoms related to obstructive hydrocephalus. There is no consensus about the management of symptomatic CSP and CV cysts. We present, to the best of our knowledge, the first systematic review of the different treatment options for symptomatic CSP and CV cysts. We conducted a literature review using PubMed database, searching for cases of symptomatic CSP and CV cysts managed surgically, and published until April 2019. Preoperative characteristics, surgical procedure, and postoperative outcome were analyzed using SPSS® software (Statistical Package for Social Sciences, IBM®). We found 54 cases of symptomatic CSP and CV cysts managed surgically (34 males, 20 females, 1.7/1 male to female ratio). Mean age was 24.3 ± 20.1 years. The most common presentation was headaches (34 patients, 62%), followed by psychiatric symptoms (27 patients, 49.1%). Preoperative radiological hydrocephalus was present in 30 patients (54.5%). The most common surgical procedure was endoscopic fenestration (39 patients, 70.9%), followed by shunting (10 patients, 18.2%), open surgery (3 patients, 5.5%), and stereotactic fenestration (1 patient, 1.8%). Complete resolution of symptoms was achieved in 36 patients (65.5%) and partial resolution in 7 patients (12.7%), and symptoms were unchanged in 2 patients. The present review suggests that surgical treatment could provide resolution of the symptoms in most of the cases, regardless of the procedure performed. Although mean follow-up was short among the studies, recurrence rate was low.

Abstract
OBJECTIVE To review and systematize literature data on the incidence of cysts of septum pellucidum, cavum vergae and cavum veli interpositi, their clinical manifestations, indications for surgical treatment and optimal surgical approach. MATERIAL AND METHODS An analysis included 72 manuscripts devoted to epidemiology, pathophysiology, clinical symptoms and results of surgical treatment of brain cysts. Case reports, series of cases, reviews and original studies were analyzed. RESULTS Septum pellucidum cavity is always formed throughout an embryogenesis and persists in 20.34% of adults. Cavum vergae is observed in 2.32% of adults. Cyst of septum pellucidum is detected in 0.04% of adults. Analysis of 368 cases of cysts of septum pellucidum, cavum vergae and cavum veli interpositi has shown that clinical picture consists of headache (50% of cases), convulsive syndrome (23.6%), reduced intelligence (20.1%), behavioural disorders (15.8%), dizziness, nausea and vomiting (10.9%). Hydrocephalus occurs in 16.6% of cases. Endoscopic wall fenestration is preferred for cyst management. CONCLUSION Brain cysts are rare and characterized by non-specific clinical manifestations. Symptomatic cyst is an indication for surgical treatment. Surgical treatment usually ensures regression of symptoms and low risk of complications.

Abstract
Cysts of the septum pellucidum (CSP) are usually asymptomatic; however, in some cases they can begin expanding and cause neurological deterioration. The mechanism leading to the formation of an expanding cyst of the septum pellucidum (ECSP) is not known. Based on observations made during endoscopic treatment of ECSP we analyzed intraoperative findings in respect to cyst formation mechanism and treatment prognosis. A group of 31 patients was studied. Only cases with bulging cyst walls occupying the frontal horns observed on imaging studies were included. The main symptom was a severe, intermittent headache. In three cases short term memory deficits were diagnosed. In one case papilloedema was observed. All patients underwent endoscopic fenestration of the ECSP. There were no cases of cyst reocclusion during a follow-up period of 1–14 years (mean 6.2 years). In 30 cases headaches resolved completely and in one case its intensity was significantly smaller. There was one case of postoperative hemiparesis. In all but two cases the thin, translucent region in the anterior part of the cyst floor was found. In the region small fissures and in three cases choroid plexus were observed. Endoscopic fenestration is the efficient treatment for ECSP. ECSP is formed on the basis of not completely closed, developmental communication of the cyst with other fluid spaces. The communication is opened by transient elevation of intraventricular pressure, and acts as a valve leading to fluid accumulation among the walls of the previously asymptomatic cavum septum pellucidum.

Abstract
INTRODUCTION Treatment of symptomatic intracranial cysts remains a controversial issue. We present a risk/benefit profile of a minimally invasive, not yet described, stereotactic internal shunt implantation technique. The provided data might serve as a reference against which other treatment modalities could be compared. METHODS From our prospective database, we identified a consecutive series of patients with symptomatic, untreated cysts who had undergone internal shunting from 2009 to 2017. We estimated the rates of clinical symptom improvement (RCSI), cyst reduction, total complications, and long-term complications. A minimal follow-up of 6 months was required. The prognostic factors were obtained from logistic regression models. Cyst recurrence-free survival was calculated using the Kaplan-Meier method. The outcomes data were compared with those from reported alternative treatment strategies using χ2 statistics. RESULTS We included 38 patients. The cyst locations differed greatly and included the cerebellum (n = 2), brainstem (n = 5), and pineal area (n = 4). Cyst-associated hydrocephalus (n = 6) resolved after treatment. The 2-year cyst recurrence-free survival rate was 97%. The RCSI and rate of cyst reduction, total complications, and long-term complications was 91%, 97%, 11%, and 2.6%, respectively. We did not find any risk factors associated with the rate of total complications. The RCSI and rate of total and long-term complications compared favorably (P < 0.01) with the corresponding estimates of alternative treatments (P < 0.01). CONCLUSIONS The described stereotactic internal shunt implantation technique is safe and can be successfully applied for treatment of cystic formations in any location in the brain.

Abstract
Background The import of the cavum variation and its prevalence rate in healthy individuals is still not clear, likewise in neurologically diseased patients. Purpose To evaluate the frequency and pattern of caval variations in neurologically diseased patients. Material and Methods The presence or absence of the cavum septum pellucidum (CSP), cavum vergae (CV), or cavum velum interpositum (CVI) was reviewed from successive cranial computerized tomography (CT) images of patients who were aged 6 months and above. Two hundred and seventeen cranial CT images were reviewed. Results At least a cavum variation was noted in 130 (59.9%) of the CT scan images reviewed. The CV, CVI, and CSP were noted in 86 (39.6%), 53 (24.4%), and 50 images (23%), respectively. Caval multiplicity was noted in 102 patients (47%). There was no significant difference in the rate of occurrence of cavum variations in patients with congenital brain diseases and acquired brain conditions (P = 0.484), neither was there a significant difference in the frequency of cavum variation in children aged older than 6 months compared to adults (P = 0.101). Conclusion Cava variations are relatively common in neurological brain diseases. Patients with congenital brain diseases did not have a higher frequency of cava variation when compared with those that had acquired lesions. The most common type of cavum variation noted in this study was the vergae variety, while the CSP is the rarest.

Abstract
OBJECTIVE Cysts of the septum pellucidum (CSPs) may become symptomatic because of obstruction of cerebrospinal fluid flow, resulting in increased intracranial pressure and hydrocephalus requiring surgical intervention. Endoscopic fenestration may be the most effective and least invasive technique to treat this pathological condition. CLINICAL PRESENTATION An 11-year-old boy sought treatment for frequent episodes of severe headache. On examination, he had papilledema. There was evidence on magnetic resonance imaging scans of a space-occupying CSP with obstructive hydrocephalus. INTERVENTION The endoscopic technique of fenestration of both lateral walls of an enlarged CSP via a left frontal approach under ultrasound guidance using a rigid endoscope was successful. After surgery, the patient became asymptomatic, his papilledema resolved, and magnetic resonance imaging scans demonstrated collapse of the walls of the CSP toward the midline. CONCLUSION Neuroendoscopic fenestration should be strongly considered as the treatment of choice for symptomatic CSPs. This procedure alone can lead to complete resolution of clinical symptoms and hydrocephalus, can reduce the size of the CSP, and can obviate the need for an implantable cerebrospinal fluid shunt.

Abstract
Abstract
OBJECTIVE:
Ten rare cases of symptomatic septum pellucidum cysts in patients who underwent endoscopic fenestration are described. The approaches and techniques used in the management of these cysts and the endoscopic surgical indications are discussed.
CLINICAL PRESENTATION:
In the past 5 years, 10 patients (age range, 3–60 yr) with symptomatic septum pellucidum cysts underwent neuroendoscopic fenestration. The most common symptom was intermittent headache (seven patients) accompanied by dizziness, vomiting, and epileptic seizures. Two patients presented with epileptic seizures. One patient presented with abnormally increased head circumference. Magnetic resonance imaging scans of 10 patients showed septum pellucidum cysts, two with hydrocephalus, and two with pituitary microadenoma.
INTERVENTION:
All 10 patients underwent endoscopic fenestration with a rigid endoscope via a frontal approach. Eight cases were performed freehand. Two cases were assisted by a frameless neuronavigation system. Postoperatively, the mass effect of the cysts and the symptoms resolved immediately, and computed tomographic or magnetic resonance imaging scans showed significant decrease in the cyst size and no recurrence during follow-up. Ventricular sizes in the two patients with hydrocephalus were normal.
CONCLUSION:
Neuroendoscopic pellucidotomy could be an effective, safe, and convenient therapeutic method for symptomatic septum pellucidum cysts. This approach might provide communication between the cyst and the ventricular system, thus avoiding shunting or craniotomy. We consider that it is appropriate to use the rigid endoscope via the frontal approach. It is helpful to fill the ventricles with lactated Ringer's solution and leave an external drain after surgery.

Abstract
OBJECTIVE Since there is no current consensus on the diagnostic standards or surgical indications for symptomatic cysts of the septum pellucidum (CSP), we presented our experience treating such cases with neuroendoscopic surgery in order to possibly make a contribution to the attainment of such a consensus. METHODS In the last 5 years, we effectively treated 5 patients (4 males and 1 female) with CSP by neuroendoscopic surgery. The 3 congenital cases were young: 9, 14, and 29 years old. The 2 secondary cases were adults aged 51 and 65 years old. We were able to fenestrate, and biopsy for pathological analysis, the cyst walls of symptomatic CSP using a minimally invasive neuroendoscopic technique, with postoperative improvement in compression of adjacent structures, as well as clinical signs. CONCLUSIONS It is necessary to consider the overall picture including clinical signs, progress of the condition, intracranial pressure, and cerebral circulation, in deciding whether surgery is indicated. Neuroendoscopic surgery is an effective, optimal, and convenient therapeutic modality for symptomatic CSP.

Abstract
In the office practice of pediatrics, the clinical threshold for order-ing imaging studies of the brain and spine has fallen in recent years, and requests have multiplied for consultation .o assess the meaning of unexpected imaging findings. Familiarity with the most common entities that precipitate such requests allows the pediatrician to allay parental anxieties with informed preliminary counseling and to set appropriate priorities for subsequent referrals and investigations.

Abstract
Several cases of enlarged cavum vergae have been reported, but prenatal diagnosis of this condition is very rare. We report 3 cases of dilated cavum vergae diagnosed prenatally using sonography. In 1 of the 3 fetuses, ventriculomegaly and lumbar meningomyelocele were additional sonographic findings. In 1 of the 3 infants, a stereotactic cyst-peritoneal shunt was placed at 6 months of age to relieve intracranial hypertension due to progressive enlargement of the cavum vergae. The infant who had a meningomyelocele required surgical repair of this defect shortly after birth; in the third infant, the dilated cavum vergae remained asymptomatic, and no surgery was necessary. When interhemispheric cystic lesions are identified prenatally, physicians must distinguish them from pathologic cysts and determine whether associated malformations are present. Sonography is useful for both the differential diagnosis and identification of associated anomalies.

Abstract
This case involved a 26-month-old boy who had recurrent hemorrhagic venous infarction caused by venous sinus occlusion. Distension and enlargement of the cavum septi pellucidi (CSP) and cavum vergae (CV), along with hydrocephalus, was detected during the course of the disease and was observed to regress together with resolution of the venous occlusion. Venous hypertension caused by sinus occlusion was thought to be responsible for the disturbed resorption of cerebrospinal fluid (CSF) in the CSP and CV in this patient. This case is unique because it is the first one to support the hypothesis of resorption of CSF in the cava by a pressure gradient involving the septal capillaries and veins.

Abstract
BACKGROUND To establish a rational basis for intraoperative ultrasound guidance in neurosurgical procedures via a single burr hole approach based on the experience of one hundred cases. METHODS The single burr hole approach is carried out using a bayonet-shaped ultrasound transducer with a tip dimension of 8 x 8 mm. The ultrasound probe with a mounted puncture adapter fits a standard burr hole and allows real-time imaging of the ongoing surgical steps. RESULTS One hundred cases with five indications have been operated on so far: tapping of the ventricular system (46 patients), tapping of intracranial cysts (23 patients), biopsy of intracranial tumors (15 patients), evacuation of intracranial abscesses (9 patients), and evacuation of intracerebral hematomas (7 patients). Depending on their size, the ventricles could be clearly visualized in 34 of 46 patients. In the remaining patients the free margin of the falx served as orientation. Two ventricles could neither be visualized nor entered. Visualization and puncture of intracranial cysts were easy to achieve throughout, as was the case with abscesses. Tumor biopsy was unsuccessful in two patients harboring lymphomas at distances of more than 50 mm from probe to target. Intracerebral hematomas were easily visualized but, due to the presence of clots, aspiration was impossible in two patients. One patient with a giant glioblastoma died the day after the uneventful biopsy due to increased cerebral edema. No other complications occurred. CONCLUSIONS The presented method of ultrasound-based neuronavigation is an easy-to-use, fast, and safe technique of real-time imaging for free-hand single burr hole procedures.

In each case, tissue from the cyst wall was studied to define the origin of the cyst wall and fluid. CLINICAL PRESENTATION The patients, a 6-year-old boy and a 42-year-old man, each presented with headaches and a syncopal episode. Imaging studies demonstrated large septum pellucidum cysts with obstruction of the foramina of Monro. INTERVENTION The patients underwent endoscopic transventricular cyst fenestration with a 4-mm steerable fiberscope. The fenestrations were created to allow communication with the right and left lateral ventricles. In one patient, adhesions between the cyst wall and the foramen of Monro were lysed with endoscopic monopolar cautery. Tissue from the cyst walls was removed for examination by electron microscopy. Postoperatively, the headaches and syncopal episodes resolved in both patients. CONCLUSION Endoscopic fenestration of symptomatic septum pellucidum cysts produces immediate relief of the mass effect of the cyst and resolution of associated symptoms. Cannulation of the lateral ventricle before cyst fenestration prevents inadvertent injury to the fornices, thalamus, internal capsule, caudate nucleus, and septal and thalamostriate veins. The endoscopic approach allows the surgeon to ensure communication within the ventricular system, thus avoiding placement of a shunt. Preliminary ultrastructural analysis indicates that the cyst walls derive from the septum pellucidum rather than the choroid plexus or arachnoid. The cellular machinery necessary for fluid secretion was identified in some specimens.

Abstract
Endoscopic surgery represents a new and very useful modality of treatment for intracranial cysts. The authors review the cases of 19 patients with intracranial malformative CSF cysts (seven intraventricular, six paraventricular, and six arachnoid) who underwent endoscopic fenestration by using a burr-hole approach. The various endoscopic approaches and techniques of fenestration, according to the type and location of the cyst, and the causes of unsuccessful outcome are critically discussed. The authors recommend endoscopic fenestration as the treatment of choice for patients with para- and intraventricular cysts, in whom the procedure may help to avoid the microsurgical approach and shunt placement in nearly all patients. In patients with arachnoid cysts, the endoscopic procedure, although associated with a lower rate of successful outcome, may be performed as the primary procedure in most cases because it is a minimally invasive procedure; the traditional surgical treatment may be performed without additional risk in which endoscopic surgery has failed.

Abstract
BACKGROUND The cavum veli interpositi is a not infrequent radiologic finding in both children and adults, as confirmed by computed tomography (CT) and magnetic resonance (MR). A moderate enlargement of the cavum may sometimes be observed; on the other hand, a true large cyst may be considered exceptional, with only one reported case. CASE HISTORY This 9-year-old boy with psychomotor retardation and epileptic seizures had a large CSF cyst in the region of the cavum veli interpositi, diagnosed by CT and MR. The patient was treated by endoscopic surgery, with introduction of the endoscope into the occipital horn of the right lateral ventricle and multiple fenestrations from the right ventricle to the cyst, and then from the cyst to the left lateral ventricle. The surgery resulted in decrease in the size of the cyst and reduction of the frequency of seizures. DISCUSSION AND CONCLUSIONS Children with dilated or cystic cavum veli interpositi present with a large head, mental retardation, seizures, and hydrocephalus. On CT and MR, the cyst shows a typical triangular configuration on the axial plane and lies on the roof of the third ventricle in the coronal plane. Endoscopic ventricular fenestration is the treatment of choice for these as well as all other intraventricular and intracerebral CSF cysts, because it ensures communication between the cyst and the ventricular system and avoids definitive shunting of the cyst.

Abstract
The cavum septi pellucidi (CSP) and cavum Vergae (CV) are persistent, primitive, or acquired, midline structures of adult human brain. It is customary to distinguish between the non-communicating and the communicating cava, depending on whether the cavum communicates with the cerebral ventricular system or not. Only a few cases of symptomatic non-communicating cava, called septum pellucidum and cavum Vergae cysts, have been described in the literature. In this study, the authors describe the morphological, histological and histo-immunological characteristics of an additional case of septum pellucidum-cavum Vergae cyst in a forty-year-old man who died the day following a ventriculo-peritoneal shunt. We have found a communication between the CSP and the leptomeningeal space of the anterior interhemispheric fissure, in the absence of subarachnoid haemorrhage. The authors discuss the origin of the intracystic fluid and the classification of the CSP.

Abstract
CASE REPORT A 6-year-old boy had symptoms such as unstable gait, behavioral symptoms, and irregular appetite, evacuation, and sleep. Giant cavum septi pellucidi and cavum vergae of 3 x 3 x 5 cm were revealed by computed tomography (CT) and magnetic resonance imaging (MRI). After stereotactic cyst-peritoneal shunting, regression of the cavities was revealed by CT and MRI, in association with marked improvement in the above-described symptoms. In the corpus callosum particularly, which had been preoperatively revealed on sagittal MRI sections to be extended circumferentially as a result of compression by a cyst; the compression was relieved postoperatively, and compression of the pericallosal brain tissue was also relieved. CONCLUSIONS Compression of the brain tissue around the cyst (limbic system, etc.) was considered the most important cause of the behavioral symptoms in this patient.

Abstract
Three children with hydrocephalus and expanding cysts of the cavum septi pellucidi and cavum vergae are reported. In all the patients, the hydrocephalus was present before the persistent cava started to expand. The cava increased gradually, until they became cystic, but their growth did not affect the size of the ventricles. Two of the patients were treated with internal cystoventricular shunts, causing a prompt collapse of the cysts but no change in the concomitant hydrocephalus. In the third patient, the persistent cava started to expand only when a previously implanted ventriculoperitoneal shunt failed temporarily. The cyst disappeared when the shunt resumed its function. The possible mechanisms underlying the expansive growth of persistent cava are discussed. We propose the theory that the growth of the cava in our patients may be the result, rather than the cause, of the hydrocephalus.

Abstract
The treatment of congenital midline cysts remains a controversial issue. The stereotactic management of 27 patients (6 symptomatic cavum septi pellucidi/cavum Vergae, 6 suprasellar cysts, 5 intraventricular cysts, 4 parasagittal cysts, and 6 supracollicular cysts) is reviewed. In 23 patients stereotactic ventriculo-cystostomy by catheter implantation (internal drainage) led to clinical recovery or improvement accompanied by decreased cyst size. In four patients the internal drainage was not sufficient and was therefore completed as a ventriculo-atrial shunt system. Three minor complications (bleeding, aseptic meningitis, catheter infection) led to no sequelae. The results suggest that stereotactic internal drainage of these benign lesions is a safe, minimally invasive and efficient procedure.

Abstract
Two paediatric patients with expanding cysts of the cava Vergae et septi pellucidi are presented. In the first patient, consecutive CT scans showed a growing cavum thought to be responsible for his dramatic increase in head circumference. In the other patient, the expanding cavum was discovered because a routine skull X-ray after minor head trauma revealed marked impressiones digitatae. Both patients were successfully treated with stereotactically placed internal shunts from the cysts via the lateral ventricle to the subarachnoid space. During this procedure, contrast medium was instilled, and the cysts were visualized on postoperative CT scans. Some dynamic aspects of such expanding cava are discussed.
