Mid-Esophageal Diverticulum Mimicking an Aortic Aneurysm on Chest Radiography.

BACKGROUND: Mid-esophageal region is an uncommon location of esophageal diverticula, a condition usually diagnosed in elderly individuals.

CASE REPORT: We report a case of an elderly male with incidental finding of mediastinal lesion, which was initially thought to be an aortic aneurysm. Further evaluation demonstrated a mid-esophageal diverticulum at the level of the carina. We present patient's medical history and imaging, followed by a discussion on symptoms and management.

CONCLUSIONS: Knowledge of benign conditions that might mimic a mediastinal vascular pathology is important for therapeutic and prognostic reasons, as they are often managed conservatively.
