1) Pulmonary tuberculosis may develop in an area of lung which is the site of pre-existing emphysematous bullae.
2) The combined process may present a bizarre picture suggesting extensive caseation and cavitation.
3) Fluid levels may develop in such bullae, apparently due to tuberculous changes in their walls. It is believed this is a hitherto undescribed disease complex.
4) The presence of bullae apparently has no effect upon the prognosis of the tuberculous process. However, the development of fluid levels in such bullae may be an indication of a spread or reactivation of the tuberculous process in a juxta-bullous location.
5) If the bullae are diagnosed as tuberculous cavities, one may be led to give a falsely poor prognosis or to recommend unnecessary extensive thoracic surgery.
