An Overview on the Role of MRI in Diagnosis and Management of Berry Aneurysm

Berry aneurysms are also known as saccular aneurysms are pathological dilatations of intracerebral arteries, that are typically located within the anterior circulation of the brain. the exact etiology of their formation is still enigmatic, but it’s postulated to be multifactual, through an interplay between familiar disposition, environmental factors, and degenerative processes. They are approximately found in around 3% of the general population. But the majority of cases are asymptomatic and are only detected accidentally. We aimed to review the literature looking into the role of MRI in the diagnosis of berry aneurysms. PubMed database was used for articles selection, papers were obtained and reviewed. Rigors number of studies have looked into the efficacy of MRI in the diagnosis of berry aneurysm, which has shown that MRI is as highly sensitive and specific as other diagnostic modalities chiefly CTA and DSA. Moreover, the utilization of different techniques such as HRMRI can lead to its use as a risk assessment and prediction tool of future ruptures. Additionally, it is considered to be the safest method due to its lack of ionizing radiation, contrast administration, or catheterization, making it the ideal choice for screening in an asymptomatic patient.
