Coronal and axial images show a well-defined water density lesion lying within the mediastinum. There is no systemic arterial supply to the lesion, and it is not connected to the tracheobronchial tree. Appearances are compatible with a mediastinal bronchogenic cyst. Scanning parameters: 80 kV, 57 eff mAs, 60 ref mAs, 0.85 CTDIvol, 13 DLP
