A 74-year-old man with 2-year cognitive decline and memory loss. The patient had Lyme-positive serum EIA and Western blot (IgG and IgM) and CSF pleocytosis with CSF positive Lyme IgM and IgG antibodies. The patient improved with intravenous ceftriaxone therapy. The “dot-dash” callososeptal interface (A) and periventricular distribution of involvement (B) would be routinely ascribed to a demyelinating process.
