title: Acute symptoms due to a huge duplication cyst ruptured into the esophagus.
abstract: A 36-year-old housewife complained of a tight feeling in the pharynx with increasing dysphagia, dyspnea, and mild fever. Chest roentgenogram was interpreted as a cystic mass in the middle mediastinum. Computed tomography showed a cystic mass compressing the carina and the esophagus. Ten days after onset, symptoms were suddenly relieved followed by a tarry stool. The chest mass shadow decreased. Esophagofiberscopy showed two fistulas communicating with a cyst that had two chambers. Thoracotomy performed 40 days after onset showed a true duplication of the esophagus with rupture into the esophagus. This is a rare case in which it was possible to observe the sequence of events of a ruptured intramural duplication cyst by means of chest roentgenography, computed tomography, esophagofiberscopy, and cystogram.
