title: [A case of tuberculous peritonitis].
abstract: We report a case of a 73-year-old man with tuberculous peritonitis. He had sought treatment at a clinic near his house for his fever and abdominal distension. Massive ascites were found and he was referred to our hospital. The endoscopy and abdominal CT scan performed on admission revealed no abnormal findings except the massive ascites. Mycobacterium tuberculosis (MT) DNA was detected in the ascitic fluid by polymerase chain reaction (PCR) and ascitic adenosine deaminase (ADA) activity was 127.6 U/l. He was diagnosed as tuberculous peritonitis and transferred to the Department of Respiratory Medicine. A chest CT scan showed predominant right pleural effusion with no other abnormal findings in bilateral lung fields. His sputum were all positive by smear acid-fast staining, MT DNA and culture on MT. His final diagnosis was tuberculous peritonitis, pulmonary tuberculosis, and tuberculous pleuritis. Treatment was started by anti-tuberculosis drugs with combined use of isoniazid, rifampicin, ethambutol, and pyrazinamide. The therapy was continued for 6 months. The culture for MT (Mycobacteria Growth Indicator Tube) converted to negative after 2 weeks of treatment and the C-reactive protein level became normal after a month. The pleural effusion and ascites disappeared after 2 and 3 months, respectively. Tuberculous peritonitis is a relatively rare disease, however when we encounter unexplained ascites, MT PCR and the measurement of ADA should be done considering a rapid diagnosis of tuberculous peritonitis, before invasive diagnostic laparoscopy.
