Abstract

PRIMARY type pulmonary tuberculosis is considered to be principally a disease of the lungs. The great importance of the bronchi has received little attention. Their role is probably most clearly demonstrated by cases in which lobar or segmental shadows are presented. A review of present knowledge concerning these shadows follows.

In 1920 Eliasberg and Neuland1 described a large shadow in the lungs of a few children who were not very ill and had positive tuberculin reactions. This shadow was of an even density, wedge-shaped, with its apex toward the hilus, and covered the area of an entire lobe.

Starting from the periphery, the process of clearing-up may take from a few months to more than a year. These shadows were most frequently found in the middle or upper lobes. A similar shadow may also be caused by caseous pneumonia. Which of these two diseases actually existed became evident by
