Abstract
A thickened posterior tracheal stripe (wider than 4.5 mm) was identified on the lateral chest radiographs of 20 patients with squamous cell carcinoma of the esophagus. Autopsy studies confirmed that periesophageal lymphatic involvement was responsible for the thickening of the stripe in the nonobstructed esophagus. This sign appeared on the lateral chest radiograph as early as 6 mo. prior to the development of symptoms in 50% of the cases studied.
