On the scout view, there is a superior mediastinal mass compressing the trachea.The projection above the cravicles implies a posteriorly located mass.
There is a 32 x 27 x 35mm (AP x TV x CC) posterior mediastinal cystic mass, with HU=22, which is displacing and compressing the trachea anteriorly. This is located just above the aortic arch level. The esophagus is also severely compressed and displaced to the right side of this cystic mass.
Right lower lobe (posterior segment) consolidation is also evident.
Oesophageal duplication cysts are rare congenital malformation, difficult to differentiate from bronchogenic cysts on imaging (oesophageal duplication cyst vs bronchogenic cysts) As such histology is required to make the differentiation. This was a typical presentation in this case.
