Disseminated tuberculosis (TB) is a life-threatening disease resulting from the hematogenous spread of Mycobacterium tuberculosis. Miliary pattern on chest radiography is a common finding that has an important role in the early detection of the disease. Chest radiography and tuberculin test are not contributing in the diagnosis. Imaging studies are helpful adjunct tools for disseminated TB as they can help determine the involved sites and guide technicians to obtain appropriate specimens for diagnosis. Clinical confirmation of the diagnosis of disseminated TB is usually based on bacteriological or histological evidence.we report four cases of disseminated of Tuberculosis involving two and more sites.
