[Extrapulmonary tuberculosis: radiological imaging of an almost forgotten transformation artist]

Tuberculosis (TB) continues to be one of the infectious diseases with the world's highest rates of avoidable morbidity and mortality. A continuing downward trend has only been observed in highly industrialized countries, including Germany with 4,400 cases in the year 2009 representing an incidence of 5.5 per 100,000 persons. At the same time, the exposure to this patient group and the clinical experience are decreasing. Tuberculosis may affect any organ. The lung was the manifestation site in 80% of cases, and extrapulmonary manifestations were recorded in 20% of cases in Germany in the year 2008. Lymph node involvement is most common with a rate of approximately 50% of all extrapulmonary cases followed by the pleura in 18% of cases, genitourinary tract in 13% of cases, bones and joints in 6% of cases, gastrointestinal tract in 6% of cases, the central nervous system in 3% of cases and the spine in 3% of cases. Symptoms like fever, night sweats and weight loss are non-specific and may be absent. The aim of the review is to raise awareness of this disease, which is increasingly falling into oblivion, with its various radiological manifestations and to point out clinical-epidemiological and demographic factors that raise suspicion of tuberculosis.
