Abstract

Verifying the prevalence of incidental cerebral aneurysm diagnosed by magnetic resonance imaging (MRI) between men and women. This research is a descriptive retrospective, database-based cohort study. The sample is composed of 1,545 patients. We use cross-tabulations to perform the absolute and relative frequencies. The Mann-Whitney U-Test was used to compare results between sexes. Incidental aneurysms have a higher relative frequency in women. The age of the highest incidence is 51 to 60 years for both genders. The risk factors present in both sexes are hypertension, dyslipidemia, smoking, diabetes, and polycystic kidneys. The women present a higher incidence of aneurysms in the posterior communicating arteries and internal carotid artery. For the men, there is a higher incidence of aneurysms in the anterior communicating arteries and the basilar artery. Modifiable risk factors are mostly responsible for the growth and development of aneurysms. In sum, the prevalence of incidental cerebral aneurysms in women occurs in a 3: 1 ratio to men, but this prevalence ranged from 2:1 to 9:1 among the years surveyed.
