Severe acute liver injury associated with .

is a Gram-negative bacterium that causes foodborne illnesses, typically characterised by acute febrile gastroenteritis and is associated with a variety of manifestations. Isolated febrile illness without gastrointestinal symptoms is rare. We report a case of   infection with severe anicteric hepatitis. A 33-year-old Chinese man with no significant medical history presented on multiple occasions to the emergency department with recurrent high-grade fever and chills, but without gastrointestinal symptoms. Hepatic panel showed rising transaminases that peaked at Aspartate Aminotransferase (AST) of 991 U/L and Alanine Aminotransferase (ALT) of 1664 U/L. CT of the abdomen revealed terminal ileitis and mesenteric adenitis. As part of workup, we found positive serology for Ultimately, he improved with supportive care. This case highlights the importance of thorough workup of terminal ileitis and 'Crohn's mimics' which ultimately revealed a unifying diagnosis; and an important addition to the workup for undifferentiated severe isolated hepatocellular liver injury.
