Intravitreal silicone oil migration into the subarachnoid space and ventricles: A case report and review of literature

Abstract

We report a case of intravitreal silicone oil migration into the subarachnoid space and cerebral ventricles, as seen on CT and MRI. During several admissions over the course of 23 months, the silicone oil was seen tracking along the optic apparatus and subsequently appeared in the ventricles as free-floating droplets. The patient experienced repeated headaches, but was worked up extensively for possible intracranial hemorrhage before the correct diagnosis was recognized.
