F. Varoli et al., False radiographic appearance of a right bronchial stump following extended right pneumonectomy, J THOR IMAG, 14(4), 1999, pp. 312-315
The authors describe three cases in which postoperative frontal chest radio
graphs following extended right pneumonectomy showed a right hilar lucency
producing the false appearance of a residual main bronchus that is shown by
additional studies to represent a dilated esophagus.
