Peritoneal tuberculosis in children: report of two cases]

Peritoneal tuberculosis is an uncommon presentation of extra-pulmonary tuberculosis in children. It usually presents as ascites, abdominal pain, anorexia and weight loss. CASES REPORT: We report two adolescent patients who presented with ascites, fever, weight loss and abdominal distension. In one case, the diagnosis was late, and confirmed by ascites culture. In the second case, a laparoscopy was performed and showed whitish nodules involving the entire abdominal cavity, compatible with peritoneal tuberculosis, later confirmed bacteriologically. CONCLUSION: Peritoneal tuberculosis presents with nonspecific symptoms. Because laboratory investigations may not be helpful, diagnosis may be difficult. Peritoneal-fluid adenosine deaminase (ADA) determination and coelioscopy seem to be the best way to make a rapid diagnosis.
