School ager with back pain

Plain film and CT and bone scan of osteoid osteoma of the spine
AP radiograph of the thoracic spine (left upper) shows a mild curvature of the spine convex right and the left pedicle of the T12 vertebral body is difficult to visualize. Axial CT without contrast of the T12 vertebral body (right upper) shows a lesion with a lucent nidus surrounded by a sclerotic rim in the left pedicle of the T12 vertebral body. Pinhole (left lower) and whole body (right lower) images from a nuclear medicine bone scan show focally increased radiotracer localization in the left pedicle of the T12 vertebral body and a curvature of the spine convex right.

The diagnosis was painful scoliosis secondary to an osteoid osteoma in the left pedicle of the T12 vertebral body.

Teenager status post radiation therapy to the spine now with a curvature to the spine

CXR of post radiation scoliosis
CXR AP (left) taken as an infant shows a round left-sided soft tissue mass that was in the posterior mediastinum and found to be neuroblastoma that was subsequently treated in part with radiation therapy. CXR AP (right) taken 17 years later shows a curvature of the upper thoracic spine convex to the right.

The diagnosis was post radiation scoliosis in a patient with neuroblastoma.

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 in a patient with a neurenteric cyst.
