Recurrent bilateral Mycobacterium bovis necrotizing epididymitis: A case report

Abstract

Background: Mycobacterium bovis causing tuberculosis in animals is responsible for zoonotic tuberculosis in patients. Veterinary control measures and milk pasteurization has led to a significant decrease in human cases of M. bovis infections in developed countries. Case presentation: We diagnosed recurrent M. bovis epididymitis in a 63-year old Caucasian man without any signs of pulmonary or disseminated disease. Relevant epidemiological expositions included camel milk drinking during prolonged travels in Niger, prior to initial clinical manifestations. The diagnosis was firmly established by mass spectrometry and DNA sequencing on epididymis surgical biopsy specimens. We detail therapeutic management which included surgical epididymectomy and hydrocele repair. Conclusion: As for other M. tuberculosis complex species, the genitourinary tract represents a frequent site of secondary dissemination and latency for M. bovis. Isolated epididymis infection is a newly documented manifestation of M. bovis disease.
