Specific cholecystitis: an unusual presentation of extra pul
The present case has been published in the International Journal of Infectious Diseases. A 26-year-old male presented with 12kg weight loss during the previous three months and recurrent abdominal pain in the right upper quadrant for nine months. Noteworthy, the patient had visited Vietnam repeatedly.

Physical examination and laboratory tests including serology were unremarkable, except for a minimal relative eosinophilia, vitamin D deficiency and a positive interferon-gamma release assay. Abdominal MRI and thoracic CT were performed demonstrating a thickened gallbladder as well as suspicious lymph nodes nearby.

Based on multiple nodules in the upper lung sputum and broncho-alveolar lavage were assessed by stain, PCR and culture, but all remained negative. Finally, an endosonographic biopsy of the enlarged abdominal lymph nodes was performed and PCR of samples detected rifampicin sensitive M. tuberculosis.

Conventional culture eventually also became positive. After four-fold therapy including isoniazid (INH), rifampicin (RMP), pyrazinamide and ethambutol for two months, INH and RMP were continued for 10 months and the patient recovered completely.
