Tuberculosis in the peritoneum: not too rare after all

Peritoneal tuberculosis is rare with increased incidence rates in recent years. The absence of characteristic clinical features of the disease often makes its diagnosis difficult and elusive. We present the case of 61-year-old female with peritoneal tuberculosis. The patient suffered from abdominal pain for a period of 5 months prior to admission. The diagnosis was established on the basis of findings from an abdominal computed tomography scan, a chest radiograph and histopathological analysis of the laparoscopic resection of the two masses. The patient was discharged from hospital receiving a fourfold antituberculous treatment with isoniazid, rifampicin, pyrazinamide and ethambutol. A high index of suspicion and a combination of radiologic, endoscopic, microbiologic and histopathological examination achieves diagnostic accuracy and prevents clinical mismanagement.
