Description

In order to know the mechanism of perforation of tuberculous empyema, 52 cases of perforated empyema and 15 of non-perforated encapusulated pleurisy were observed pathohistologically and clinically.<BR>In most of the c a ses, exudative pleurisy or artificial pneumothorax was found in the previous history, and the period from the previous illness to the presumed time of perforation ranged from 9 to 38 years, on the average 17 years, except one case. The size of pleural sack on X-ray film before perforation was somewhat larger than non-perforated cases, and enlargement of pleural sac was detected 12 months, on the average, before perforation in one third of the perforated cases.<BR>From the macroscopic examination of the resected specimens, 4 types of perforation was recognized; Fig.2. Type A, with bronchial or pulmonary fistula, was found in 27 cases, and was thought to be perforation from the empyema to the lung. Three cases of type B. having triangular ulceration of the lung parenchym, was also suspected to be originated from type A change.
