Objective: Dysphagia is a common symptom encountered in clinical practice. Etiology varies from benign disorders such as gastroesophageal reflux disease to more life-threatening conditions such as neoplasms. Esophageal duplication cysts occurring in the lower esophagus may result in external compression contributing to dysphagia. We describe the case of a mediastinal lymphatic malformation, mimicking an esophageal duplication cyst and causing external compression of the esophagus presenting as dysphagia Methods: Here we describe a case report of 55 year old male who presented with dysphagia, odynophagia and weight loss and underwent multiple studies to reveal a 6 x 2 x 2 cm sized mass posterior to the esophagus, extending from the mediastinum to the esophageal hiatus. Excision of the mass was planned and performed with a minimally invasive approach. Results: We describe the successful minimally invasive removal of a mass expected to be an esophageal duplication cyst, with pathology confirmation of a mesenteric chylous cyst. Conclusions: Mediastinal lymphatic malformation causing dysphagia is a condition that has rarely been described in the literature. Its clinical presentation may mimic an esophageal duplication cyst or other extrinsic esophageal masses. Surgical resection should be considered for confirmation of diagnosis and resolution of dysphagia.
