In the majority of cases the infiltrate was predominantly lymphocytic, usually composed of T cells (CD3+/CD5+/CD4\>CD8) with relatively few CD20+ B cells and few neutrophils. Overt tissue destruction was rare.Conclusions: CTLA4 mutations are associated with a distinct pattern of neuroinflammation. Supported by available pathology, the clinical-radiological discordance suggests that even large, enhancing lesions need not be destructive, even when behaving as space-occupying masses. Further characterization and modeling of this genetic disorder may provide insight into the mechanisms underlying other neuroimmunological disorders.Study Supported by: Fellowship funding from the National Multiple Sclerosis Society-American Brain Foundation.
