The aim of this study is to report the coexistence of retinal arterial macroaneurysms (RAMs) and cerebral aneurysms (CAs) in a 58-year-old woman with hypertension. She was noted as having a 1-week history of vision loss in her left eye, along with a 2-month history of a nonspecific headache. Visual acuity was 20/32 in her left eye and 20/20 in her right eye. A fundus examination revealed multiple areas of retinal hemorrhages that were surrounded by circinate exudation in her left eye, as well as the generalized attenuation of the retinal arteries in both of her eyes. Angiographically, hyperfluorescent round leakage points confirmed the presence of five saccular RAMs. Surprisingly, computed tomography angiography completed based on the recommendation of neurology department identified three saccular CAs. Aging, hypertension, and female preponderance are the common risk factors for both RAMs and CAs. Accordingly, RAMs and CAs may exist simultaneously in hypertensive patients.
