Anatomical variations of the intracranial arteries and their association with intracranial aneurysms: Insights from digital subtraction angiographies.

The purpose of this study was to identify the anatomical variants (AVs) in the intracranial arterial circulation of patients who underwent neuro-interventional procedures (NIPs) and to describe their relationship with intracranial aneurysms (IA). We performed a cross-sectional analysis of angiographic images from patients who underwent NIP at the Interventional Neuroradiology Department of the National Institute of Neurology and Neurosurgery in México between July 1, 2020, and January 1, 2022. After reviewing images from 150 NIPs, we found 144 AVs.

Brain metastases in a patient with antecedent of cardiac myxoma: a case report and review of literature.
