- Abstract
Purpose: To investigate diffuse large B-cell lymphoma lesions with central nervous system (CNS) involvement in patients with vitreoretinal lymphoma (VRL) during long-term clinical courses. Study design: Multicenter, retrospective, and observational research. Methods: Seventy-one patients participated in this study, 45 were newly diagnosed VRL patients with CNS involvement initially or during follow-up of at least 12 months. We identified the CNS lesions in the patients that had VRL and investigated whether the onset sites of the CNS lesions were associated with the VRL lesions or optic pathways. Results: There were 42 patients with bilateral ocular lesions; 29 had unilateral lesions; 26 had incidental CNS lymphomas. Twenty patients developed recurrent CNS lymphoma 1–73 months after VRL diagnosis; 25 patients had no CNS lesions during the follow-up period. Most CNS lesions were in forebrain-originating tissues (95 lesions/total 124 CNS lesions total), followed by hindbrain-originating tissues, especially the cerebellum. Sixty-seven lesions were found in the non-optic pathway or non-visual cortex. Conclusion: Over 60% of the VRL patients had CNS lesions. CNS involvement was not associated with the optic pathway or visual cortex, suggesting that clinicians should carefully examine CNS lesions occurring in both forebrain- and hindbrain-originating tissues during a patient's clinical course. Moreover, the CNS lymphomas that manifest as VRL show multifocal tumor development.
