The most common mediastinal cysts include bronchogenic cysts, enteric duplication cysts, pericardial cysts, and thymic cysts, though most of these cysts appear in the middle mediastinum with the exception of thymic cysts in the anterior mediastinum. Bronchogenic cysts can be ciliated and may stain positive cytokeratin (CK7) positive but rarely stain PAX8, WT-1, and ER positive [5].
