Objective: Saccular (berry-shaped) aneurysms that develop at arterial bifurcations—branch points where an artery splits into two branches—are the most common type of intracranial aneurysms, which are aberrant focal dilatations (localized bulges) of cerebral arteries. When they burst, cerebral artery aneurysms (CAA) pose a serious risk of morbidity and death. This case series aims to analyze computed tomography cerebral angiography (CTCA), a medical imaging method for the screening, diagnosis, and follow-up of patients with cerebral artery aneurysms that uses CT scans to show cerebral arteries.
Conclusion: Recent years have seen a significant change in the diagnosis and treatment of cerebral aneurysms. With CTCA, radiologists can accurately describe pertinent results, such as the risk of aneurysm rupture, and reliably and noninvasively identify the majority of intracranial aneurysms. Additionally, it helps identify high-risk groups and recommend screening. Treatment is becoming safer and more efficient thanks to nonoperative endovascular treatments, which are minimally invasive operations carried out inside blood vessels.
