Preoperative Considerations • The transcallosal approach allows midline exposure of the anterior two-thirds of the third ventricle. • Preoperatively, in addition to standard MR imaging, venography is often helpful to…
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…
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…
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)…
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…
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…
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…
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 ). Figure 8.1…
Indications • Intra-axial lesions are located in close proximity to the motor cortex (rolandic and perirolandic regions including the supplementary motor area). The infiltrative rather displacing nature of gliomas makes…
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….
