The rupture of smaller counterpart aneurysms in patients with multiple intracranial aneurysms.

ABSTRACT: In case of multiple (unruptured) intracranial aneurysms (M[U]IA), deciding which intracranial aneurysms (IA) should be treated and which at first can be challenging. The most accepted risk factor in making these decisions is IA size. However, a smaller intracranial counterpart aneurysm (SICA) and not the largest IA in patients with MIA might cause subarachnoid hemorrhage (aSAH). By falsely assessing a SICA as benign and withholding treatment, these patients are put at risk for SICA rupture before treatment. Therefore, there is a paramount need to improve the identification of more rupture-prone SICA, especially regarding the improved accessibility to intracranial imaging leading to increasing incidences of patients with (M)IA. From our institutional observational cohort, containing data of
