Objective: The aim of the present study is to investigate the potential morphological and
hemodynamic risk factors related to intracranial aneurysms (IAs) rupture and establish a …

A diagnosis of an intracranial aneurysm depends on the angiographic configuration and
should be cautiously differentiated from aneurysm mimics. In cases of duplicate anterior …

Background As infundibular dilation (ID) is less likely to cause hemorrhage or other clinical
sequelae than an intracranial aneurysm (IA) and treating infundibulum itself may put the …

The feasibility of multicentric international data such as integrated in the PHASES score for
patient counseling in unruptured intracranial aneurysms has recently been challenged. To …

Thought to be benign anatomical variants, cerebral infundibular dilatations (ID) are most
commonly encountered at the junction of the internal carotid artery (ICA) and the posterior …

Purpose Replaced posterior cerebral artery (PCA), defined as a hyperplastic anterior
choroidal artery (AChA) supplying all branches of the PCA, is an extremely rare anatomical …

Background While anatomic features associated with the risk of posterior communicating
artery (PcoA) occlusion after embolization of aneurysms of the PcoA segment of the internal …

Oculomotor nerve palsies are typically associated with posterior communicating artery
(PcommA) aneurysms. We report a rare case of an oculomotor nerve palsy caused by a …

Background Infundibular dilations (IDs) are funnel-shaped enlargements located at the
origin of cerebral arteries. Neuroradiologists and neurosurgeons are familiar with IDs of the …

Abstract Purpose Unruptured intracranial aneurysms (UIAs) at the distal internal carotid
artery (ICA)(segments C5–C7) are difficult to accurately display on computed tomography …
