Abstract
BACKGROUND: Intraocular injection of silicone oil is commonly performed during vitrectomy to tamponade the retina in place for treatment of retinal detachment. Although rare, this intravitreal silicone can migrate through the optic nerve and chiasm and enter the cerebral ventricles.
CASE DESCRIPTION: Here we present a case report of a patient presenting with headache and intraventricular hyperdensities on computed tomography imaging raising concern for intraventricular hemorrhage. The intraventricular hyperdensities, however, were in a non-dependent location and moved to a new non-dependent location when a repeat imaging was performed with the patient in a prone position. We provide a literature review of this phenomenon and discuss the relevant CT and MRI findings.
CONCLUSION: Intraocular silicone can rarely migrate into the cerebral ventricular system. Careful review of the clinical history and imaging findings can help distinguish this from other, more dangerous intracranial pathologies.
