BACKGROUND Campylobacter-jejuni infection can lead to different extraintestinal manifestations. Myo-/pericarditis and toxic hepatitis have been reported. A combined appearance has not been described yet. METHODS A 22-year-old woman presented with sudden left thoracic pain. An increase in troponin T, creatine kinase and myoglobin was noted. In the absence of signs of myocardial ischemia, the diagnosis of myocarditis was made. The patient reported diarrhea persisting for 5 days. Campylobacter-jejuni could be identified in the feces. On account of rising transaminases, a biopsy of the liver was performed. The histological examination revealed lesions caused by Campylobacter-jejuni. CONCLUSIONS Given the increasing incidence of Campylobacter-jejuni infections, the case presented here should draw the attention to extraintestinal manifestations.
