The diagnosis of miliary tuberculosis in the very young is difficult. In the lungs, for instance, without consolidation and without cavity, miliary tuberculosis may be strongly suspected, but not easily proved.
I submit herewith two helps to the diagnosis — one, of the lungs — the x-ray; the other of the skin — the eruption. The first case selected for illustration shows both diagnostic signs and will be submitted complete. The best recent x-ray apparatus has made it possible to produce the accompanying pictures, which speak for themselves. In six cases of infants and young children suspected of disseminated miliary tuberculosis of the lungs, the x-ray has cooperated with other tests to decide the diagnosis. For illustration of what can be done, the best x-ray plate has been selected, the best print made from it and the best result obtainable here presented (Fig. 1).
