Be aware of abdominal tuberculosis

Abdominal tuberculosis is often diagnosed in a late stage because symptoms are aspecific. Two patients with intestinal tuberculosis and tuberculous peritonitis respectively, both from endemic countries presented with long-standing fever, abdominal pain and weight loss. Acid fast bacilli were present in aspirate and biopsy specimens obtained by colonoscopy and laparoscopy respectively; PCR was positive for M. tuberculosis complex and later M. tuberculosis was cultured. Both patients responded to antituberculous therapy. In one patient AIDS was diagnosed.
