Abstract: | A patient with a peculiarly refractoy uveitis and vitritis was later found to have an infiltrative mass lesion of the posterior portion of the corpus callosum. The histopathological diagnosis of reticulum-cell sarcoma (large-cell lymphoma) was made after study of vitreous tissue obtained by pars plana vitrectomy of the right eye. Intraocular involvement with cerebral reticulum-cell sarcoma has been reported previously. |
