A 17-year-old girl with congenital rubella syndrome underwent glaucoma filtration surgery with Ahmed glaucoma valves (AGV). The T2 hyperintense fluid-filled blebs on either side of the T2 hypointense central silicone plate of the AGV on coronal magnetic resonance imaging (MRI) of the orbit showed up mimicking a burger (arrows) [Figure 1].[1] Hence, we termed this the "burger sign" so that radiologists and ophthalmologists are aware of this distinctive feature and can differentiate it from other cystic orbital lesions such as dermoids.[2]
