Esophagobronchial fistula and mediastinal tuberculosis.

A 59-year-old man was seen with what preoperatively was thought to be an acquired esophagobronchial fistula secondary to an old burned-out infection with tuberculosis. At operation the gross and microscopic findings were most compatible with a congenital H-shaped esophagobronchial fistula. However, cultures of calcified lymph nodes grew Mycobacterium tuberculosis. The need for culturing calcified tissue to assure proper treatment is emphasized.
