- Tracheoesophageal stripe
The tracheoesophageal stripe is formed by the posterior wall of the
trachea and the anterior wall of theesophagus . This line is best identified on the lateral chest x-ray. When this line is greater than 5 mm it is considered abnormal.The most common cause of a thickened tracheoesophageal stripe is
esophageal carcinoma , however,lymphadenopathy likely cannot be excluded and further evaluation with additional imaging is recommended.References
