Each minute, three people die of tuberculosis worldwide. Abdominal tuberculosis is an infrequent but serious form of disease and can affect any abdominal organ. Being a health-care worker is one of the most important risk factors for developing tuberculosis (TB). TB transmission between patients and health care-workers has been reported in virtually every country in the world and constitutes a big public-health problem. We describe a TB case in a young female physician whose clinical presentation started with chest pain, the initial workup did not show evidence of disease, after and six months, she developed abdominal symptomatology. Clinical, radiological (computed tomography (CT) and positron emission-tomographyecomputed tomography (PET-CT)) and microbiological workup allowed diagnosing tuberculous peritonitis, she completed anti-TB treatment and recovered completely. Clinical, radiological, and diagnostic approach for abdominal of TB, with special attention to our patient features, is discussed in this paper; also, a brief revision about the PET-CT utility in TB diagnosis is presented.
