Clinicopathological characteristics and prognostic factors of atypical meningiomas with bone invasion: a retrospective analysis of nine cases and literature review.

Background: Meningiomas are the most common primary neoplasms of the central nervous system in adults, arising from the arachnoid cap cells. Thus, grade 2 meningiomas are situated on the border between benignity and malignancy. Among the many prognostic factors that have been investigated in these tumors, bone invasion is one of them.

A cases series of endovascular and microsurgical combined treatment of intracranial aneurysms.

Objective: Our scientific paper is aimed at describing multimodal treatment of intracranial aneurysms represented by microsurgery and endovascular therapy.

Patients, Materials And Methods: We report four cases of intracranial aneurysms treated in our Department of Neurosurgery by microsurgery (clipping) and endovascular treatment (coiling), through the joint efforts of a team of highly skilled neurosurgeons.

Results: Mixed treatment has been imposed by the complications we were presented with, resulting from either of the two surgical methods employed.

Predictor factors for recurrence in atypical meningiomas.

Background And Objectives: Atypical meningiomas (AMs), World Health Organization (WHO) grade 2, are a group of tumors with uneven and unpredictable clinical behavior. Our aim was to analyze possible tumor recurrence predictors, and to identify factors that improve progression-free survival (PFS).

Patients, Materials And Methods: Our retrospective study included 81 patients followed up in the Prof.

A Case Series of Surgical Resection of Anterior and Posterior Butterfly Glioma Grade 4 via a Minimally Invasive Keyhole Approach.

Surgical resection of infiltrating glial neoplasms has proven to improve quality of life and confer a significant survival benefit. As accumulating evidence cements the role of surgery in grade 4 gliomas, there is a general trend to transition away from traditional large craniotomies to smaller 'keyhole' approaches, which aim to reduce the trauma and complication profiles associated with large exposures. A keyhole approach uses a small craniotomy positioned perfectly to reach at least all the target structures that a conventional approach would reach.

Tumor recurrence in parasagittal and falcine atypical meningiomas invading the superior sagittal sinus.

Objective: Parasagittal and falcine meningiomas are still a challenge in terms of surgical resection. Although maximal safe resection is the main therapeutic approach, numerous postoperative complications can still occur depending on the locations of these tumors. Moreover, previous studies have reported that parasagittal meningiomas have a higher recurrence rate than meningiomas with other locations.
