Purpose
The aim of this study is to describe the most frequent forms of extrapulmonary tuberculosis (TB) when the lung is not involved or pulmonary imaging is nonspecific.
Although the improvements in diagnosis and treatment,
TB still remains a world health problem,
especially in developing countries.
Etiology,
ways of dissemination
TB is due to Mycobacterium tuberculosis,
an aerobic non-spore-forming bacillus.
The mechanism of destruction is given by cell-mediated hypersensitivity that induces caseous granuloma formation.
The primary site of infection is represented by lung and concerns approximately 70% of cases.
Extrapulmonary infection generally occurs as a result of hematogenous dissemination from a clinically occult pulmonary focus.
Extrapulmonary TB may be confused with a neoplasm or other diseases.
As a consequence,
an accurate identification becomes important to establish an appropriate therapy.
