From: Intracranial silicone oil migration with encephalopathy: a rare case report
A Axial NCCT image of bilateral orbits shows silicone oil globules in the right vitreous chamber (arrows) and silicone oil tracking along the right optic nerve sheath. Also, note the partially treated retinal detachment on the right side and an untreated total retinal detachment on the left side (asterisks). B Axial T2W MR image of the right globe shows chemical shift artefact at the interface of the silicone oil with the vitreous chamber, seen as thin curvilinear hyperintense band anteriorly (white arrows) and thin hypointense band posteriorly (yellow arrows). Intraventricular silicone oil globule located within the right temporal horn (which is not seen in the prior CT image, owing to its mobile nature) showing chemical shift artefact
