Abstract

The CT findings are described in five patients with esophagomediastinal fistula due to tuberculous lymphadenitis. In all five patients periesophageal amorphous gas collections were found along with enlarged mediastinal lymph nodes. In four patients esophagograms demonstrated the fistulas. All fistulas closed with antituberculous therapy alone. The presence of periesophageal gas in patients with tuberculous mediastinal lymphadenitis suggests esophago-nodal fistula. The treatment of choice is antituberculous therapy.
