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.

In this video, the authors present an interhemispheric transcallosal transchoroidal approach to a pineal mass in a 15-year-old boy. He received emergency endoscopic third ventriculostomy (ETV), then an endoscopic biopsy that revealed an immature teratoma. Surgical removal was selected. The mass was located very high in the posterior third ventricle, hidden behind the splenium of the corpus callosum and the vein of Galen, so an interhemispheric transcallosal approach followed by a complete dissection of the whole choroidal fissure was chosen and allowed complete removal of the tumor. Microsurgical dissection is presented, showing clearly in detail all the neurovascular structures encountered. The video can be found here: https://stream.cadmore.media/r10.3171/2021.4.FOCVID2126.

✓ The authors report a patient with bilateral papillomas of the choroid plexus of the lateral ventricles with documentation of cerebrospinal fluid (CSF) hypersecretion causing hydrocephalus. Special attention is given to the large volume of CSF produced by these tumors (removal of one tumor reduced CSF outflow by one-half) and to the fact that CSF diversion was not required after both tumors were removed. Since tumor removal alone was sufficient to stop the progression of hydrocephalus, we feel that this case supports the concept that elevated CSF production by itself is sufficient to cause hydrocephalus in patients with papillomas of the choroid plexus.

Results Of Surgery

Object Nonfunctioning pituitary adenomas (NFPAs) are benign tumors of the pituitary gland that typically cause visual and/or hormonal dysfunction. Surgery is the treatment of choice, but patients remain at risk for tumor recurrence for several years afterwards. The authors evaluate the early results of surgery and the long-term risk of tumor recurrence in patients with NFPAs. Methods Between 1990 and 2005, 491 previously untreated patients with NFPA underwent surgery at the Università Vita-Salute. Determinations of recurrence or growth of the residual tumor tissue during the follow-up period were based on neuroradiological criteria. Results Residual tumor after surgery was detected in 173 patients (36.4%). Multivariate analysis showed that invasion of the cavernous sinus, maximum tumor diameter, and absence of tumor apoplexy were associated with an unfavorable surgical outcome. At least 2 sets of follow-up neuroimaging studies were obtained in 436 patients (median follow-up 53 months). Tumors recurred in 83 patients (19.0%). When tumor removal appeared complete, younger age at surgery was associated with a risk of tumor recurrence. In patients with incomplete tumor removal, adjunctive postoperative radiotherapy had a marked protective effect against growth of residual tumor. Conclusions Complete surgical removal of NFPAs can be safely achieved in > 50% of cases. Visual symptoms and, less frequently, pituitary function may improve after surgery. However, tumor can recur in patients after apparently complete surgical removal. In patients with incomplete tumor removal, radiation therapy is the most effective adjuvant therapy for preventing residual tumor growth.

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.

Ventricular Tumors

Central neurocytomas are rare benign tumors that are typically located in the lateral ventricles. Because they are typically intraventricular, these tumors tend to present clinically with hydrocephalus. Currently, surgical removal with a gross-total resection is the treatment of choice. Various radiotherapy techniques, including both conventional radiotherapy and stereotactic radiosurgery, have been shown to be useful in cases of residual tumor after subtotal resection and tumor recurrence. This chapter presents a clinical case of central neurocytoma that demonstrates the typical clinical and radiological findings, as well as the diagnostic workup and surgical management of these tumors.

AbstractMetastasis to the calvarium with direct pericranium or dural infiltration may be treated with radical surgical removal in selected cases. We describe microsurgical resection of calvarial metastases with fluorescence-guided technique using 5-aminolevulinic acid (5-ALA) in two female patients with breast cancer. Fluorescence findings were positive in both cases. Margins in the scalp and dural layer were 5-ALA negative at the end of surgical removal. Intraoperative pathology was performed in all cases to confirm if oncological limits were free of disease. One case was 5-ALA positive in the outer layer of the dura-mater and another in the pericranium. At the end of the removal in both cases, the surgical margins were 5-ALA fluorescence-free. Intraoperative pathology confirmed oncological limits of the resection. 5-aminolevulinic acid fluorescence-guided surgery for calvarial metastases with pericranium and/or dural extension seems to be a safe and reliable method to aid the surgical margins for complete removal, possibly delaying or avoiding adjuvant irradiation for progression control.

Post-surgical rehabilitation of children with benign tumor injuries of the jaws. Introduction. Tumors in children have a specific and constantly current topic. With the advent of new diagnostic technologies, there is an increasing incidence of tumors in children. The peculiarities of the growth and development of the child from newborn to adolescent highlight new and new problems of morphofunctional and psycho-emotional rehabilitation, both immediately after treatment and at a distance. The purpose of the study was to find out the problems that appear in children after the surgical removal of benign tumors from the jaw region. Results. During 2020 year, 66 children with benign tumors of the jaws were found. The children underwent surgical treatment to remove the tumors. It has been found that tumors located in the mandible are two times more common than those located in the upper jaw. The period of morphofunctional rehabilitation of the child after the removal of the tumor depending on the growth of the tumor and the peculiarities of the dentomaxillary system, we have three categories of children. Children with tumor removal in the block. Children with tumor removal by curettage. Children with palliative tumor removal. Rehabilitation methods include restoring the dental arch with removable applines. In group two, remodeling the growth of the jaws with the positioning of the permanent teeth. Group three includes tooth repositioning, jaw remodeling, and tooth eruption stimulation. Conclusion. Tumors with localization in the jaws during the growth and development of the child require complex rehabilitation, immediately after treatment and at a distance, with a personalized character depending on the postoperative defects and the age of the child.

Thalamic Lesions

Abstract In managing thalamic gliomas, total surgical removal is the most effective way of increasing overall survival. However, the thalamus is a difficult target because of surrounding neurovascular structures. According to the lesion's size/location/growth pattern, relation to neighboring structures, and surgeon's experience, most thalamic lesions can be reached through one of the 4 free surfaces: lateral ventricle, velar, cisternal, and third ventricle surfaces of the thalamus (3VsT).1-3 Approaching the thalamic lesions through the lateral side disrupts the integrity of internal capsule and corona radiata; thus, we never prefer this approach. For the removal of the lesions on the 3VsT, a transcallosal approach can be considered, but with this approach, we cannot reach 3VsT without harming the velar surface.  In this 3-dimensional video, we demonstrate an endoscope-assisted contralateral perimedian supracerebellar suprapineal (CPeSS) approach to a glioma on the 3VsT. The patient, a 49-yr-old man, had progressive dizziness for a month. With the patient in a semisitting position, total resection was achieved via the endoscope-assisted CPeSS approach. This approach is entirely transcisternal-transventricular and is a natural route to the 3VsT. Although the route is longer than the ipsilateral approach, it requires no retraction and provides more direct and wider visualization. It allows complete visualization of the lateral border of the lesion. A perimedian approach also avoids the major tentorial bridging veins, which are mostly at the midline. High-definition neuroendoscope was a great adjunct that helped to visualize residual tumors at hidden corners.  We suggest this approach for thalamic lesions on the third ventricle surface of the thalamus.  The patient consented to the publication of his images and a written consent was obtained.
