ΣSUVmax variations between the beginning and end of treatment and during follow-up post-treatment, in patients considered cured [ Time Frame: 6 to 18 months ] [ Designated as safety issue: No ]
To measure FDG uptake and evolution, the ΣSUVmax will be used. SUV ("Standard Uptake Value") is defined as tissue concentration of FDG / administered FDG dose / patient weight. ΣSUVmax is the sum of the maximum SUV measured in every TB foci. ΣSUVmax variations between the beginning and the end of treatment, and 6 months later in cases of persistent uptake at the end of treatment will be studied in patients considered cured

Positron Emission Tomography in Extrapulmonary Tuberculosis
Evaluation of Positron Emission Tomography in Extrapulmonary Tuberculosis

Tuberculosis (TB) remains a major public health problem. In extra-pulmonary forms, evidence of bacteriological cure is difficult to be obtained raising the need for other therapeutic assessment tools. 18F-Fluoro-deoxy-glucose (FDG) is a glucose analogue widely used in Positron Emission Tomography (PET). Its uptake is high in cancer cells and in inflammatory cells, especially in active TB foci. The hypothesis is a decrease in the uptake of FDG in the foci of TB during treatment permitting a non-invasive monitoring of therapeutic response. The main objective is to describe the evolution under treatment of the FDG uptake in PET imaging in TB foci in patients cured from lymph node and bone TB. Secondary objectives are to compare the decrease of FDG uptake according to type of location, to define the frequency of localizations revealed by FDG-PET and their impact on therapeutic management at the beginning and the end of treatment, and to describe the evolution of PET in patients not cured.

Longitudinal observational multicenter pilot study. 55 patients to be included Total duration of the study: 36 months. Inclusion period: 12 months Follow up period: 18 to 24 months Number of participating centers: 8 Average number of inclusion per month per center: 1-2
