Silicone oil tamponade is a frequent treatment for retinal detachment. Intraventricular migration of this agent is rare, but was described previously in patients with chronic glaucoma and atrophy of the optic disc. We describe a patient with prior silicone oil tamponade in the left eye with a noncontrast computed tomography demonstrating hyperattenuating material along the course of the left optic nerve and in the frontal horns of the lateral ventricles, and emphasize the use of prone noncontrast computed tomography as an important diagnostic tool in order to confirm the low specific gravity of the oil agent.
硅油填充是视网膜脱离的常见治疗方法。该药物的脑室内迁移很少见，但此前在慢性青光眼和视神经萎缩患者中有所描述。我们报告一名曾行左眼硅油填充的患者，其非增强计算机断层扫描显示沿左侧视神经走行及侧脑室额角有高密度物质，并强调使用俯卧位非增强计算机断层扫描作为重要的诊断工具，以确认油剂的低比重。
