Roentgenologic Diagnosis of Lead Poisoning in Infants and Children

My purpose in this paper is primarily to demonstrate certain roentgenologic signs of lead poisoning in infants and children and incidentally to call attention to the relative frequency of this condition as well as its possible serious consequence. Like any disease, the apparent incidence is greatly influenced by the importance it bears in the clinical consideration, but it is also true that many cases will go unrecognized if some convenient diagnostic procedure is not readily available.

Since August, 1929, when we first began to recognize the roentgenologic signs, till the present time thirty-two cases have been diagnosed in this clinic. Quite a number were detected on the roentgenograms before they were otherwise suspected, but the increased number recognized is due
