Abstract
Tuberculosis is an infectious disease that most often affects the lungs, caused by human-to-human transmission of Mycobacterium tuberculosis. Peritoneal tuberculosis is an extra-pulmonary form of the disease that usually manifests as an ascitic syndrome, with or without fever, in a context of altered general condition, often in endemic areas. The diagnosis of peritoneal tuberculosis is not always easy, as the clinical signs are often insidious and unspecific. We report a case of peritoneal tuberculosis in an 18-year-old female, who had presented for 10 days with a progressive increase in abdominal volume associated with vomiting and diarrhoea.
