A primary lesion of the left main bronchus, a secondary lesion of the esophagus and a metastatic lymph node in the mediastinum. (A) The metastatic lymph node in the mediastinum and esophageal lesion are displayed in the maximum intensity projection image (red arrowhead and arrow). (B) PET image displayed the primary lesion (red arrow) at the beginning of the left bronchus. (C) No positive findings were found on axial CT. (D) PET/CT image demonstrated the primary lesion (red arrow) at the beginning of the left bronchus increased 18F-FDG uptake. PET, positron emission tomography; CT, computed tomography; 18F-FDG; 18F-fluorodeoxyglucose.

Thickening of the esophageal duct wall. Abnormal 18F-FDG uptake in the esophageal lesion and the metastatic lymph node in the mediastinum. (A,B) The maximum density projection and axial PET image. (C,D) The axial CT and PET/CT image. PET and PET/CT images showed increased 18F-FDG uptake in esophageal lesion (arrows in A, B and D). The mediastinal metastatic lymph node increased 18F-FDG uptake (A, red arrowhead). In addition, axial CT of the mediastinal window showed uneven thickening of the esophageal wall (C, arrow). PET, positron emission tomography; CT, computed tomography; 18F-FDG; 18F-fluorodeoxyglucose.

Plain and enhanced CT of the chest. (A) Pre-radiotherapy non-enhanced chest CT shows uneven circumferential thickening of the wall of the lower esophagus (stars) with isodensity (39 HU) and mass formation (white arrow). (B) Mild enhancement (45 HU) of the esophageal wall in the arterial phase (white arrow). (C) The esophageal wall still has increased enhancement (55 HU) in the venous phase (white arrow). (D) Significant strengthening (87 HU) of the esophageal wall during the delayed period (white arrow). (E) Localized hypointense area within the tumor after enhancement suggests possible tumor necrosis (white arrow). (F) Axial enhanced CT show enlarged lymph nodes with enhancement (white arrowhead). CT, computed tomography; HU, Hounsfield units.

CT and upper gastrointestinal imaging after radiotherapy. (A) Right anterior oblique X-ray shows esophageal sinus tract formation (short black arrow). (B) Mediastinal paranasal sinus cavity is noted in the left anterior oblique image (long black arrow). (C) Radiograph of left anterior oblique indicates a flow of contrast medium into the bronchi of the lower lobe of the right lung (black arrowhead). (D) Axial CT demonstrates the entrance to the esophageal sinus tract (short white arrow). (E) Sinus tract exit is pointed out (long white arrow). (F) The flow of contrast medium into the bronchi of the lower lobe of the right lung is clear on the CT image (white arrowhead). CT, computed tomography.
