Figures

Figure 1.
Figure 1.
Upper gastrointestinal series fluoroscopy of a 13-year-old patient with persistent cough and multiple previous episodes of pneumonia. The anteroposterior view demonstrates a smooth indentation of the left wall of the esophagus. The lateral view confirms the indentation, which now appears to be compressing the anterior wall of the esophagus. The upper third of the esophagus is dilated, which is most apparent on the lateral view. The smooth indentation is marked by a blue double-sided arrow.
Figure 2.
Figure 2.
Follow-up computed tomography with intravenous contrast of the same patient with persistent cough and multiple previous episodes of pneumonia. Two consecutive coronal reformatted images of the chest at the level of the carina showing the origin of the retrotracheal aberrant right subclavian artery (red arrows).
Figure 3.
Figure 3.
Follow-up computed tomography with intravenous contrast of the same patient with persistent cough and multiple previous episodes of pneumonia. The axial and sagittal reformatted images (A and B, respectively) from the same imaging study as Figure 2 again demonstrates the rare retrotracheal course of the aberrant right subclavian artery (green and blue arrows in A and B, respectively). The aberrant right subclavian artery is seen interposed between the trachea (T) and the esophagus (E). Compression on the more malleable esophagus (E) is more readily apparent on the sagittal reformatted image (B).
