A woman in her 30s presented with a 3-month history of bilateral blurry vision with transient visual obscurations and a 1-month history of tinnitus. Funduscopic examination findings were concerning for bilateral optic disc edema, which was worse in the right eye compared with the left (Figure 1). Magnetic resonance imaging of the brain demonstrated multiple cysts in the posterior fossa, including a large cyst inducing obstructive hydrocephalus at the level of the fourth ventricle measuring 1.2 cm × 1.6 cm in anteroposterior and transverse dimensions (Figure 2).
