title: Mediastinal pseudotumor due to passage of ascites through the esophageal hiatus.
abstract: Ascites can extend from the peritoneal cavity into the posterior mediastinum through the esophageal hiatus. This mediastinal fluid can simulate the appearance of a mediastinal tumor. Demonstration of hiatal hernia and continuity between the thoracic and abdominal fluid assist in establishing the correct diagnosis.
