Coma caused by Shigella toxin-producing Escherichia coli in the absence of haemorrhagic uraemic syndrome (HUS)

Shigella toxin-producing Escherichia coli (STEC) is well known for its complications such as haemolytic uraemic syndrome (HUS), but neurological symptoms have also been reported. While most cases of infection with STEC occur with concurrent HUS, we describe a patient with severe neurological symptoms in the absence of HUS. LEARNING POINTS: Shigella toxin producing Escherichia coli (STEC) are bacteria that cause haemorrhagic colitis. Generally, infections with STEC occur with a concurrent haemolytic uraemic syndrome (HUS). However, infections with STEC can occur with neurological symptoms without HUS.
