Popis: Purpose and patients: The incidence of skeletal tuberculosis (TB), which once accounted for a majority of cases of extrapulmonary tuberculosis, has fallen significantly in recent years with the advent of effective drug therapy. Disseminated bone involvement in TB is very uncommon but it may still occur in countries where TB is endemic. We present the imaging findings of four children ranging in age from 2 to13 years, each of whom had multiple osseous stigmata of tuberculous infection. They presented to us over a period of 9 months. Results and conclusion: Three of four children had calvarial lesions, with involvement of the bony orbit in one, and large abscesses were present in the chest wall and the mediastinum of another. Lesions along the dorsal spine were demonstrated in three cases, two of which showed epidural extensions. Bone lesions in the thoracic cage accompanying those in the spine were also seen in two children, one of whom had a solitary destructive focus in a rib distant from the site of vertebral involvement. Bone lesions involving the first metacarpal in one case and the scapular wing in two others are also described. The diagnosis in each of the cases was confirmed by the identification of epitheloid giant cells and caseous necrosis or tubercle bacilli in fine needle aspirates or on tissue culture studies.
