Lung Dust Lesions Versus Tuberculosis

This work is a contribution to the frequently perplexing subject of the differentiation between the lesions of the pneumonoconioses, such as silicosis, and those that result from other causes, particularly tuberculosis. The author's approach as discussed in the preface is essentially that of exhaustive study of pathologic and roentgenologic material correlated with personal occupational and clinical histories when possible, or those of others when personal examinations could not be arranged. His main aims are (1) to correlate pathologic and radiologic data, (2) to describe and illustrate radiologic findings and interpret them into radiologic diagnoses, (3) to identify pulmonary lesions of dust origin as distinguished from those of tuberculosis and (4) to facilitate thereby the equitable settlement of medicolegal questions of concern to both management and labor. He makes no claim that any of his investigations are original, but points out that some of the observations may not be familiar to
