Plain-English summary
A 12-year-old male miniature Schnauzer was taken for a CT scan to check a mass under his tongue. He had previously undergone eye surgery for retinal detachment, which involved using silicone oil to help with healing. The CT images showed a large amount of silicone oil in his eyes, which could be mistaken for a mass. Understanding how silicone oil appears on scans is important for vets to avoid confusion when diagnosing other issues.

Abstract
A 12-year-old male neutered miniature Schnauzer underwent computed tomography of the head for evaluation of a sublingual mass. The dog had prior bilateral pars plana vitrectomies with silicone oil tamponade and endolaser retinopexy for treatment of retinal detachment. On evaluation of the computed tomographic images, the vitreous chambers contained a large volume of smoothly marginated hyperattenuating material with a mass-like appearance, consistent with silicone oil. The imaging characteristics of silicone oil on computed tomography can be a source of diagnostic confusion, underscoring the importance of recognizing these features in dogs that may undergo computed tomography for other indications.
