[Laparoscopy can be used to diagnose peritoneal tuberculosis].

A 17-year-old man with weight loss, abdominal pain and fever for three months was admitted to the Digestive Disease Centre. Laboratory tests revealed leucocytosis and a low haemoglobin level, and a CT-scan of the abdomen indicated non-specific abscess cavities. Diagnostic laparoscopy was conducted and widespread pale nodules were found throughout the peritoneum. Consequently, the patient was diagnosed with peritoneal tuberculosis. This case demonstrates that atypical manifestations of tuberculosis exist in Denmark and that laparoscopy with biopsy can be performed to obtain the diagnosis when suspecting peritoneal tuberculosis.
