[Benign recurring aseptic meningitis. What requires our attention?].

Benign recurrent aseptic meningitis (BRAM) or Mollaret's meningitis is a rare disease characterized by recurrent episodes of aseptic meningitis followed by spontaneous recovery. Disease courses over several years have been reported. In most cases, BRAM is caused by HSV-2, less frequently by other viruses or autoimmune diseases. In up to 10 %, the aetiology remains unclear. We present a case of idiopathic BRAM and discuss clinical findings, diagnosis and therapeutic options of this rare illness.
