Clinical presentation of forgetfulness and recent memory impairment of approximately 10 years of evolution. Additionally, it is associated with nonspecific dizziness without object rotation and gait instability that has caused several falls. This clinical picture is intermittent, but 2 years ago, progressive visual loss began, leading to a cerebral MRI that revealed a left occipital cyst.

Left occipital cystic lesion. After gadolinium administration, no abnormal contrast enhancement is observed. The ventricles appear deformed due to the mass effect of the lesion, but there is no modification in the signal intensity of the parenchyma. The midline is not displaced.
