8. When there is extensive caseation and the granulomas involve a larger bronchus, it is possible for much of the soft, necrotic center to drain out and leave behind a cavity.

当存在广泛的干酪性坏死并且肉芽肿累及较大的支气管时，大量的坏死物排出，留下空洞。

9. Small lesions may exhibit no caseation.

微小病灶可不出现干酪性坏死。

10. Small lesions may exhibit no caseation, and no organism may be demonstrated.
