Clinical-Radiological Correlation of Retained Silicone Sponge Presenting as Orbital Inflammation

(a) Axial CT image identifying a hypoattenuated lesion with slight localized mass effect on the globe with surrounding soft tissue attenuation. Note the irregular, jagged borders of the lesion. (b) Coronal cut shows more definitive surrounding soft tissue attenuation. The hypoattenuation mass, which was confirmed by surgical explantation to be a retained silicone sponge element, was noted to have an attenuation of −284 Hounsfield units.
