OBJECTIVE To investigate the outcome of linac-based fractionated stereotactic radiotherapy over the last 10 years for intracranial skull base benign meningiomas in patients who were inoperable, who had residual tumors with some components of high mitotic index after surgery and who experienced relapse of the tumor. METHODS Twenty-seven patients with intracranial skull base benign meningiomas ...

Meningiomas comprise approximately 20% of adult primary intracranial neoplasms. Of these, benign meningiomas are known to have an indolent growth pattern, usually without infiltration into adjacent nervous tissue. Because meningiomas have a well-circumscribed character, surgery has historically been the preferred treatment when total resection can be achieved with reasonable morbidity. Surgical...

Jugular foramen tumors are rare cranial base lesions that present diagnostic and management difficulties. Paragangliomas were the most frequent lesions, followed by schwannomas and meningiomas. These tumors have characteristic radiological features. Radical resection of these tumors with preservation of the lower cranial nerves is the treatment of choice. Despite the advances in skull base surg...

To achieve local disease control, radical removal is the best option for sphenoorbital meningiomas. Preservation of the venous system is crucial during the resection of skull base meningiomas. This vascular injury represents a major risk both for life and neurologic function. We present a case of a severe postoperative frontotemporal venous disturbance and cerebral edema following the radical r...

Extracranial extraspinal meningiomas (less than 1% of all meningiomas) frequently occur in the head and neck. The radiographic findings of extracranial meningioma of the head and neck are not pathognomonic. However, the location of the tumor in the pathway of cranial nerves or adjacent to the skull base, the demonstration of a well circumscribed, solid, enhancing mass by computed tomography, an...

The aim of this study was to evaluate the clinical value of multislice 3-dimensional computed tomographic angiography (3D-CTA) in the preoperative assessment of meningiomas. A total of 331 cases with meningiomas confirmed by CT and MRI were examined using 3D-CTA. The locations of the tumors were observed to be as follows: parasagittal and falcine in 125 cases, sphenoidal in 39 cases, in the olf...

BACKGROUND Meningiomas are associated with the highest postoperative rate of venous thromboembolic events (VTE) among all intracranial tumors. The aim of this study is to compare two entirely different VTE prophylaxis regimens in 724 consecutive patients undergoing meningioma surgery. METHODS Two cohorts at a single institution treated with different regimens to prevent VTE were reviewed retr...

BACKGROUND The past two decades have been the setting for remarkable advancement in endonasal endoscopic neurosurgery. Refinements in camera definition, surgical instrumentation, navigation, and surgical technique, including the dual surgeon team, have facilitated purely endonasal endoscopic approaches to the majority of the midline skull base that were previously difficult to access through th...
