Case report: A 37-year-old patient with cephalgia and fever after his return from Mexico is reported. Due to persistently elevated transaminases, a liver biopsy was performed. Histological examination revealed hepatic involvement of a granulomatous disease. Serologic analyses detected anti-Brucella IgM. The suspected diagnosis was thus brucellosis taking the typical anamnesis into account. Treatment with rifampicin and doxycycline led to a complete convalescence of the patient.
Conclusion: Brucellosis is an anthropozoonosis that exists worldwide. Potential sources of infection are uncooked or unpasteurized milk and milk products of infected animals. Complete cure of most brucellosis-infected patients can be achieved by an early and adequate antibiotic treatment.
