We describe a 17-year-old girl with Kleine-Levin syndrome (KLS)

The combination of SNCA gene duplication and LRRK2 G2385R variant may explain the early onset of disease in this patient.

We report a 29-year-old man with subacute necrotizing lymphadenitis (SNL) associated with recurrent aseptic meningitis following an 11-year remission period. In both episodes, headache and fever were followed by lymphadenopathy, with increased serum IgE level. Although pleocytosis in cerebrospinal fluid was confirmed at admission in the first episode, it appeared at one week after admission in the second episode. Administration of glucocorticoid was effective for treating meningitis. The present case suggests a pathomechanism for SNL that involves both an immunological background and an acute viral infection as triggers of exacerbation of aseptic meningitis.
