Introduction Tumors of the lateral ventricle represent less than 1% of all intracranial tumors. The majority of these lesions are benign or low grade. The lateral ventricles are amongst the most challenging areas to operate in the brain and require…
Indications and Preoperative Considerations Posterior fossa meningiomas are uncommon lesions that can be found virtually anywhere in the infratentorial space. The management of these lesions will depend on their size, location, growth rate and clinical presentation. These tumors can be…
Indications and Preoperative Considerations Falcine meningiomas are extradural lesions that arise from the falx cerebri. They might be classified based on their relationship with the superior sagittal sinus (SSS) into anterior, middle or posterior lesions, each requiring different techniques for…
Indications and Preoperative Considerations Meningiomas are one of the most common primary intracranial brain tumors. They represent 34% of all primary brain tumors and originate from the arachnoid cells in the brain and spine. The brain convexity is the most…
Introduction Neuro-oncological surgery has rapidly emerged and developed as a new field in neurosurgery focused on the treatment of tumors affecting the brain, cord and the peripheral nerves. It has undoubtedly relied on a parallel advance with technology. With the…
Indications This approach is well suited for midline tumors in the pineal region: germinoma, teratoma, pineocytoma, pineoblastoma, astrocytoma, metastasis, ependymoma, epidermoid tumor, cavernoma ( Figure 8.1 ). Tumors in the midline tectal region. Midline pontomesencephalic lesions. Contraindications The approach is…
Indications In general, most focal cervicomedullary tumors are considered benign in pathology. Common tumors of the cervicomedullary region include low-grade astrocytomas, gangliogliomas and ependymomas. They are typically well-delineated and benign tumors, typically amenable to gross total resection. Contraindications Anaplastic astrocytomas…
Indications The suboccipital craniotomy is used for most lesions in the posterior fossa. Its indications are: Brain tumors such as meningiomas, ependymomas, gliomas, medulloblastomas, acoustic neuromas and metastatic lesions. Vascular lesions such as aneurysms, cavernous malformations, arteriovenous malformations and intraparenchymal…
Indications In general, surgical resection is preferred for accessible, symptomatic lesions with a focal growth pattern, while stereotactic biopsy is typically reserved for tumors with a diffuse growth pattern. If obstructive hydrocephalus is present, it is treated with a CSF…
Indications and Preoperative Considerations Selective deep-seated intra-axial tumors can be surgically resected with the use of a tubular retractor system that creates a controlled surgical corridor with minimal brain retraction and damage to surrounding brain tissue. This controlled surgical corridor…
