Introduction: Bing-Neel syndrome is a rare complication of Waldenström macroglobulinemia, defined by monoclonal lymphoplasmocytic cells in the cerebrospinal fluid or in central nervous system biopsy.
Case report: We report a 47-year-old man, with no prior history, who presented a recurrent aseptic lymphocytic meningitis with central nervous manifestations. The presence of a monoclonal lymphoplasmacytic proliferation in cerebrospinal fluid, blood and bone marrow biopsy results was compatible with a diagnosis of Bing-Neel syndrome. Despite the absence of any specific treatment, there was no recurrence of symptoms at 4-month follow-up, and the MRI lesions remained stable.
Conclusion: We report a case of Bing-Neel syndrome revealed by a recurrent meningitis. Outcome without treatment was favorable at 4-month follow-up.
