Abstract:
The case of a patient submitted to sonographic abdominal examination because of recent onset of fever, abdominal pain and weight loss, with the finding of multiple enlarged lymph nodes along great vessels, is reported. Because of the negativity of noninvasive procedures, the patient underwent laparatomy and biopsy. The histologic and bacteriologic diagnosis of tuberculous lymphnodes was unexpected, as the patient was unreactive to the tuberculin skin test and had no signs of active pulmonary tuberculosis. Although uncommon, tuberculosis must be included in the differential diagnosis of subdiaphragmatic lymphadenopathies even if symptoms of mycobacterial infection or other signs of the infections are not presented.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
