Until recent years the occurrence of cavity in the course of pulmonary tuberculosis was accepted as heralding the doom of the patient.
The study of serial radiographs, however, disclosing annular shadows that contracted and even disappeared awakened the observers to the possibility of cavities becoming not only healed but even obliterated with little or no evidence of their past occurrence.
This was not accepted at first, such annular shadows being classified as pleural shadows; but the evidence produced by many observers has established the conviction that cavities can heal with or without leaving evidence of their past occurrence.
