A 40's-year-old woman who had abdominal pain with fever was referred to our hospital for further examinations. Abdominal computed tomography showed no focal lesion, and no causative lesion was found after a gynecological examination, upper gastrointestinal endoscopy and colonoscopy. Tuberculin test and QuantiFERON-TB were positive, and thus tuberculous peritonitis was suspected. The level of adenosine deaminase (ADA) in ascites was high, and (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) showed that FDG accumulated diffusely along the peritoneum. These findings supported the findings of tuberculous peritonitis. Final diagnosis of tuberculous peritonitis was done from laparoscopic biopsy. Combination of QuantiFERON-TB, ADA and FDG-PET was useful in diagnosing tuberculous peritonitis.

A 55-year-old woman treated with infliximab for rheumatoid arthritis was admitted due to progressive ascites. A CT scan showed massive ascites, bilateral pleural effusion, disseminated granular shadows in the lung, and multiple swollen mediastinal lymph nodes. A FDG-PET/CT scan showed increases of FDG uptake in the mesentery and peritoneum, mimicking peritoneal carcinomatosis. Subsequent pleural and peritoneal fluid analysis showed elevated adenosine deaminase activity levels with no malignant cells. A right pleural biopsy specimen revealed Langhans giant cells and granulomas. Finally, a diagnosis of miliary tuberculosis was established because cultures of the sputum and gastric fluid were positive for Mycobacterium tuberculosis. Several weeks after a standard anti-tuberculosis regimen with 4 drugs was initiated, her clinical condition and radiological findings ameliorated. Since the initial manifestations of tuberculosis tend to be more severe during treatment of rheumatoid arthritis with tumor necrosis factor-alpha inhibitors such as infliximab due to immune suppression, we should pay closer attention to the possibility of tuberculosis infection in these patients.

An 85-year-old man was admitted for non-productive cough and bilateral pleural effusion on a chest X-ray film. Although his pleural effusion was exudative and showed an increased number of lymphocytes and a high level of adenosine deaminase, Mycobacterium tuberculosis infection, even with a microbiological culture, PCR and interferon-gamma release assay, was unverifiable. Cytology of his pleural effusion demonstrated plasmacytoid-like large atypical cells. Immunological tests showed high levels of IgG and IgG4 in both his serum and pleural effusion. A fluorodeoxyglucose-positron emission tomography (FDG-PET) scan showed uptake of FDG in orbital lesions, salivary glands, gastric wall, biliary system and lymph nodes (cervical, supraclavicular, axillary, hilar, mediastinal, along the lesser gastric curvature). Histological examination of an orbital pseudotumor and gastric mucosal biopsy revealed that numerous numbers of mostly IgG4 positive plasma cells, had accumulated. Based on these findings, systemic IgG4-related disease was diagnosed. Corticosteroid therapy was started and the volume of pleural effusion markedly declined. We report a rare case of IgG4-related disease accompanied by pleural effusion with a high level of ADA.
