Abstract The authors review their experience with 21 cases of intraventricular cysticercosis, which corresponded to 28% of all cases of neurocysticercosis in their department during an 18-month period. The surgical approach depends on the cyst's location; one uses the transcortical microsurgical approach to reach the lateral ventricles, the transcortical or transcallosal approach to reach the 3rd ventricle, and direct exploration to reach the 4th ventricle. Cysticercus cysts should be removed because they may produce acute or chronic hydrocephalus and, if the parasite dies within the ventricles, it will generate an inflammatory reaction with local and generalized ventriculitis, which produces irreversible neurological damage.

Abstract Two patients with xanthogranuloma of the 3rd ventricle are described. In each instance the tumor obstructed the interventricular foramina and caused dilatation of the lateral ventricles and signs of increased intracranial pressure; computerized tomography demonstrated the dense, nonenhancing lesion in the anterior 3rd ventricle. The pathogenesis of these rare tumors is discussed. These cases affirm the need to consider xanthogranuloma in the differential diagnosis of anterior 3rd ventricle tumors in adults.

Intraventricular Tumors

The interhemispheric transcallosal approach is a versatile approach to access intraventricular tumors of the lateral and third ventricles. The advantages of using a transcallosal approach over a classical transcortical approach include a direct midline orientation with symmetrical access to both lateral ventricles and both walls of the third ventricle. In addition, violation of the cerebral cortex and the risk of postoperative seizures can be avoided. Central neurocytomas are rare benign tumors that represent approximately 0.1 to 0.5% of all primary brain tumors. They are typically located in the lateral ventricles and tend to present clinically with hydrocephalus. Currently, surgical removal with a gross-total resection is the treatment of choice. In this operative video manuscript, the author demonstrates an illustrative step-by-step technique for microsurgical resection of a large central neurocytoma involving both lateral ventricles in a patient with hydrocephalus using the interhemispheric transcallosal approach. A complete removal was performed without the need for permanent shunting. The operative technique and surgical nuances, including the surgical approach, intraventricular tumor removal, and closure are illustrated in this video atlas.The video can be found here: http://youtu.be/KzC8QYsTKeg.

AIM: This study aimed to describe and analyze the advantages and disadvantages of various surgical approaches to neoplasms of the third ventricle of the brain in children. MATERIALS AND METHODS: This study analyzed surgical interventions to the third ventricle in 657 patients, performed at the Academician N.N. Burdenko of the Research Institute of Neurosurgery from 1998 to 2018. These included 375 patients with intra-extraventricular craniopharyngiomas and 282 patients with gliomas of the third ventricle and chiasm. The patients age ranged from 3 mon to 18 years old. RESULTS: The anterior transcallosal approach provides access to the anterior horn and bodies of the lateral ventricles, as well as the third ventricle. The transfornical approach provides more opportunities for access to both the anterior and posterior parts of the third ventricle; however, it has a high risk of trauma to the fornix. The subchoroidal approach provides a very good view of the posterior parts of the third ventricle, especially of the pineal region; however, it has even greater restrictions on viewing its anterior parts. When compared with the transcallosal approach, the transfrontal approach can be used more safely in the absence of hydrocephalus (if the tumor is located in the anterior horn). No specific complications were inherent in a particular approach (seizures were registered in 1%, transient hemiparesis was noted in 10%, and transient memory impairments were revealed in 5% of cases). CONCLUSION: The use of a transcallosal approach is safe even in infants. The transcortical approach is recommended mainly for large tumors of the lateral ventricles, and the transcallosal approach should be used for small tumors of the third ventricle. No specific complications were inherent in a particular approach, and the choice was determined by the assessment of the exact location of the tumor and calculation of the most relevant trajectory for its achievement as well as the aim (biopsy or radical removal). Analysis of magnetic resonance imaging and neuronavigation are significant in the selection of surgical approaches.

ABSTRACT The authors report the case history of a patient with a colloid cyst of the 4th ventricle. The clinical history of slow intracranial hypertension, homogeneous hyperdensity with contrast enhancement on computed tomographic, scan, and the gelatinous aspect of the cyst at surgery are characteristic of colloid cysts. The diagnosis was made, however, only at the time of histological examination. A common neuroepithelial origin with 3rd ventricle cysts would be explained by similar embryological developments of the prosencephalic and the rhombencephalic roofs.

Abstract Fifteen cerebellar vermian arteriovenous malformations were surgically treated over a 7-year period. Intracranial hemorrhage was the presenting symptom in 73% of the cases and recurrent bleeding episodes occurred in 60%. Computed tomographic scans demonstrated the site of the malformation in 80% and documented the presence of intracerebral bleeding in all posthemorrhage patients. Angiography revealed two consistent patterns of arterial supply depending on the involvement by the malformation of the superior inferior cerebellar vermis. All lesions were surgically removed via a midline suboccipital posterior fossa microsurgical approach. Intraventricular extension of arteriovenous malformation was common, often in association with the choroid plexus of the 4th ventricle. Immediate postoperative angiography was used to document arteriovenous malformation removal. Three instances of unsuspected residual malformation were documented and required reexploration. The total operative mortality was 7%, and the neurological morbidity was 21%.

Abstract A 9-year-old boy with bobble-head doll syndrome, precocious puberty, and progressive memory loss is described. His evaluation included computed tomographic scanning with metrizamide and air ventriculography. A cyst within the 3rd ventricle was excised subtotally by a transcallosal approach. Postoperatively, his head bobbing lessened and his memory improved.

ObjectivesTo characterise the surgical management of paediatric 4th ventricular tumours and their attendant neurological complications.DesignRetrospective cohort study.SubjectsChildren referred to our institution with tumours of the 4th ventricle between 2008–2017 inclusive.MethodsClinical notes and imaging review. Two-tailed Fisher’s test used to determine differences between proportions.Results95 patients were seen (53 males, mean 5.81y). The commonest presenting symptom was vomiting (63.3%). The commonest tumour type was medulloblastoma (54 cases)>pilocytic astrocytoma (20)>anaplastic ependymoma (12)>ATRT(4)>Teratoma (2), with 3 miscellaneous lesions. 55 pts presented with hydrocephalus. 27.4% of patients had an EVD (30.8% of these prior to tumour surgery), and 23.3% a VP shunt sited. The surgical approach was either via telovelar (50%) or transvermian (50%) routes; 29.5% were done in the sitting position. In the first 5y of the series, 7/31 cases used the telovelar approach, whilst in the latter 5y, this proportion was 30/51 (p=0.0015). New post-operative deficit was evident in 68% of cases (42.4% gait abnormality, 23.9% cranial neuropathy, 16.3% diplopia). There was no significant difference in the rates of cerebellar mutism syndrome between telovelar or transvermian approaches (p=0.62). There was 1 mortality within 30d of operation.ConclusionsResection of paediatric 4th ventricular tumours is increasingly performed by the telovelar route, and carries significant morbidity, although surgical mortality remains low.
