A 13-year-old young man with anxiety presented for echocardiogram after multiple emergency room visitations for atypical chest pain. An echocardiogram (A to E) displayed a fluid filled, tube-like structure posterior to the left atrium (LA) and parallel to the descending aorta (DAo). Chest x-ray was remarkable for a widened mediastinum, with a shadow parallel to the spine. Upper gastrointestinal study and computed tomography scan demonstrated an esophageal duplication cyst (F, *; Online Video 1). The patient underwent elective exploratory thoracoscopy, right thoracotomy, resection of the esophageal cyst, and esophageal repair.
Esophageal duplication cyst is a rare congenital anomaly, often found incidentally with computed tomography imaging. Rarely, echocardiography has discovered these lesions; however, echogenic structures posterior to the left atrium are uniquely difficult to diagnose given the complex territorial anatomy (1). AAo = ascending aorta; Eo = esophagus; LV = left ventricle; RA = right atrium; RV = right ventricle.
