MUSLIN-INDUCED OPTIC ARACHNOIDITIS (GAUZOMA) - FINDINGS ON CT AND MR

We report a case with a paraophthalmic aneurysm that was wrapped with muslin because it was unclippable. Six months after wrapping, the pati ent developed gradual vision loss involving the ipsilateral eye. Both CT and MR studies demonstrated a loculated fluid collection with marke d surrounding enhancement in the region of the previous surgery. Crani otomy revealed an abscess centered in the region of the aneurysmal wra pping. Pathological diagnosis was consistent with a foreign-body react ion with acute and chronic inflammation. Postoperatively the patient s howed improvement in vision. We describe the MR findings in this case of muslin-induced optic arachnoiditis (''gauzoma'').
