Eosinophilia myalgia syndrome

Eosinophilia myalgia syndrome (EMS) is a fatal neurological condition caused by ingestion of improperly manufactured L-tryptophan.  Impurities and/or metabolites that block histamine degradation result in peripheral blood eosinophilia and myalgia.  

In the brain, cortical and basal ganglia atrophy with diffuse white matter abnormalities may be seen.
