Scattered and extra pulmonary tuberculosis patients coinfected with HIV represent in Bujumbura (Burundi) more than 56% of tuberculosis cases. The high prevalence of these forms could be explained partly by the hospital recruitment, therefore by patients already strongly immunocompromised. Performing further examinations as abdominal echography, ganglionic biopsy (or firstly a puncture sucking procedure) permit to reveal multifocal affections. These examinations provide valuable diagnostic arguments specially among the negative bacteriological forms.
