FINDINGS T2W MR shows bilateral frontal lobe involvement from a *butterfly* lesion in the genu of the corpus callosum Enucleated eye - after vitrectomy w/silicone oil replacement - shows thickening of the posterior retina w/small round blue cells

DIFFERENTIAL DIAGNOSISWhat is your Differential Diagnosis? *Butterfly Lesions* - Astrocytoma, primary CNS lymphoma- - Retinal *blue cell tumor*- - Retinal lymphoma- - Retinoblastoma- - Chronic (benign) choroidal inflammation- - Status-post vitrectomy- - Intraocular silicone oil- - Cataract- - Angle closure glaucoma-

Diagnosis: Retinal lymphoma, large B-cell typeDx Confirmed by: Diagnostic vitrectomy and histopathology
