    COMMENTS BY DR. DALMAU

    Although the identification of a mixed popula-tion of T- and B-cells with possible expression ofCD43 in the vitreous biopsy may have suggested anocular lymphoma with CNS involvement, none ofthe subsequent studies, including CSF analysis andflow cytometry, supported this diagnosis. Moreover,expression of CD43 has been reported in non-neoplastic inflammatory disorders. Detection ofthyroglobulin and TPO antibodies is often iden-tified in patients with Hashimoto thyroiditis(a frequent cause of hypothyroidism), other thyroidand autoimmune disorders, as well as in a smallnumber of normal individuals. Our patient did nothave thyroid dysfunction, and the ophthalmologicand MRI findings did not suggest Hashimotoencephalitis, an ill-defined steroid-responsive en-cephalitis that occurs in association with thyroglob-ulin and thyroperoxidase antibodies. In contrast,the asymmetric T2 hyperintensity involving themedial temporal lobes in association with lympho-cytic pleocytosis in the CSF and rapidly progressivebehavioral change and memory deficits are highly

    Case Report (Continued)

    The patient was referred to a retinal specialist,who confirmed the fundus findings. Fluoresceinangiogram did not reveal vasculitis or retinitis. Diskstaining was consistent with edema. A vitreousbiopsy OD showed mixed T and B lymphocytes withpossible aberrant expression of CD 43, consistentwith a B-cell proliferative disorder.During the week following his initial evaluation

    the patient clinically declined with worseningvision, more confusion, and severe nausea andvomiting. He started complaining of episodicstrange odors. He was admitted to the hospital forfurther work-up.Laboratory data included normal complete blood

    count, metabolic profile, liver function tests, eryth-rocyte sedimentation rate, c-reactive protein, andB12. Thyroid stimulating hormone and free T4 werenormal, anti thyroglobulin antibodies were elevatedat 641 units/mL, and antithyroperoxidase antibodies(anti-TPO) were elevated atO3000 units/mL. Anti-nuclear antibodies were positive at 1:1280 ina pattern resembling perinuclear anti-neutrophilcytoplasmic antibody although lacked specificity
