Neurenteric Cyst

Etiology: split notochord syndrome, bronchopulmonary foregut malformation
Imaging: cyst can be prevertebral / intravertebral / ventral to the cord / intramedullary / dorsal to the cord, often associated with butterfly hemivertebra, bronchopulmonary foregut malformation

Cases of Neurenteric Cyst

CXR and CT of neurenteric cyst — CXR shows congenital scoliosis due to vertebral segmentation anomalies in the upper thoracic spine. Axial CT with contrast of the chest shows a cystic lesion to the right of the spine in the posterior mediastinum.

CXR of congenital scoliosis due to hemivertebra — 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.
