Features of treatment of patients with combination of aneurysm or arteriovenous malformations and intracranial tumors: clinical cases and a literature review

Abstract

The combination of vascular pathology of the brain and neurooncological disease is quite rare in neurosurgical practice: the combination with aneurysms is in the range of 0.7–5.4 %, while the true incidence of combinations with arteriovenous malformations (AVMs) is unknown due to the extremely rare occurrence. Such combinations present several problems, such as the early preoperative diagnosis of vascular pathology, as well as the tactics of treating such patients. There is no consensus in the literature regrading the treatment tactics for such patients.The aim of this work is to present modern approaches to the treatment of patients with a combination of vascular and oncological intracranial pathologies, as well as our own clinical cases: combinations of chordoma, tumor of the pyramid of the temporal bone,and aneurysm, meningioma of the base of the anterior cranial fossa (ACF) and aneurysm, meningioma of the base of the ACF an AVM, and glioblastoma and AVM.
