Diagnostic considerations of tumors of the sellar region according to their geometry and vector growth.

Introduction: Sellar and parasellar tumors are frequent lesions in neurosurgical practice, highlighting pituitary adenomas, craniopharyngiomas, and sellar tubercle meningiomas. The clinical manifestations are similar, however; There are imaging aspects that differentiate them.

Objective: Show imaging aspects of tumors in the sellar and parasellar region that guide their histopathological diagnosis.

Minimally invasive approach for skull base meningiomas.

Introduction: Skull base meningiomas constitute a complex group of skull base tumors. The endoscopic endonasal approaches (EEA) and endoscopic Keyhole have a minimally invasive philosophy with high effectiveness, safety, and a significant decrease in postoperative morbidity in these tumors.

Objective: To describe the results of the use of minimally invasive approaches to skull base meningiomas.
