Granulomatous hepatitis in Yersinia enterocolitica infection

Liver involvement in infections with Yersinia enterocolitica or Yersinia pseudotuberculosis is apparently rare. In a 69-year-old male patient with acute Yersinia enterocolitica infection with positive faecal culture and a serum titre of 1/1280, the liver tests were slightly abnormal. A liver biopsy revealed granulomatous hepatitis. Follow-up after six months revealed normal liver function and histology.
