Magnetic resonance imaging characteristics of posterior scleritis mimicking choroidal mass

We present imaging findings in a case of posterior scleritis, which may mim ic tumoral mass lesion resulting in unnecessary enucleation. Magnetic reson ance imaging was remarkable for a subretinal mass hypointense on T2 and hyp erintense on T1 weighted images. A peripheral rim of hypointensity was note worthy, suggestive of sclerouveal thickening, There was an ill-defined area of increased T2 signal intensity adjacent to globe at the site of nodular lesion implying an inflammatory process. A linear contrast enhancement was seen within the bulbus oculi which may represent detached retina by exudati on or displaced retina due to thickened sclera and choroidal layers. The CS F space around the optic nerve was enlarged. (C) 2001 Elsevier Science Irel and Ltd. All rights reserved.
