FIG 3. A and B, T2-weighted axial (A, case 2) and coronal (B, case 4) MR images (2000/80/1) show circumferential, hyperintense mass (arrowheads, arrows) surrounding the globe. Increased T2 signal reflects increased water content and swelling of hydrolyzed buckle material

FIG 4. Case 2.
A and B, Noncontrast (A) and contrast-enhanced (B) T1-weighted axial images (500/15/1) show soft tissue mass isointense with muscle, with peripheral rim of enhancement (arrows) corresponding to thick, fibrous capsule and foreign body reaction seen at pathologic examination.FIG 5. Case 1. T2-weighted axial image (2000/80/1) shows normal profile of an uncomplicated encircling silicone band in the right orbit (straight arrows) as compared with hydrolyzed, fragmented hydrogel buckle in the left orbit (curved arrows). An uncomplicated hydrogel band would be expected to have a similar profile to that of the silicone band
