Enteric cyst in the left posterior mediastinum mimicking a hydatid cyst on chest computed tomography scan

Mediastinal enteric cysts are a rare occurrence among adults and are usually asymptomatic. in most cases they are an incidental finding in the right hemi-mediastinum and are associated with vertebral anomalies. we report the unusual case of a 23 year old male who had a mediastinal mass on chest x-ray as an incidental finding. chest computed tomography (ct) scan revealed no vertebral anomalies and a cystic mass in the left posterior mediastinum with features similar to those of a hydatid cyst. posterolateral thoracotomy was done and the cyst was excised. histopathology report revealed it to be an enteric cyst. © 2016,university of economics - prague. all reserved.
