School ager with a posterior mediastinal mass

CXR of congenital scoliosis and neurenteric cyst
CXR AP shows a round soft tissue density in the superior and medial aspect of the right hemithorax which was found on cross sectional imaging to be in the posterior mediastinum, along with multiple hemivertebra segmentation anomalies of the lower cervical and upper thoracic spine causing a curvature of the upper thoracic spine convex to the right.

The diagnosis was congenital scoliosis secondary to hemivertebra vertebral body anomaly in a patient with a neurenteric cyst.
