Figure

• 

  Fig. 1 Chest X-ray image. The image shows tumor shadows at the right middle lung field.

• 

  Fig. 2 Thoracic CT images. Initial axial (A, B) and coronal (C, D) CT images obtained at presentation showed a large mass obstructing the right middle lobar bronchus combined with atelectasis and multiple enlarged mediastinal lymph nodes. Although these lesions were close to the esophagus, there was no direct invasion of the esophagus by the lung mass.

• 

  Fig. 3 Endoscopy images. Endoscopy images (A, B) show a strongly contracted esophagogastric junction.

• 

  Fig. 4 Barium esophagography image. The images (A, B) show minimal esophageal dilatation with pooling and stasis of contrast and narrowing of the distal esophageal segment.

• 

  Fig. 5 High-resolution manometry image. The image shows high integrated relaxation pressure (43 mmHg) with failed peristalsis and pan-esophageal pressurization.
