Reason: hx of osteoporosis and ALL. Assess for compression fractures and nerve compression. History: pain. The 12th ribs are hypoplastic. Sagittal alignment is within normal limits without sagittal spondylolisthesis.There is a wedge compression deformity involving the T12 vertebral body with approximately 40% loss of height anteriorly as well as mild retropulsion posteriorly which results in mild central canal stenosis at the T11-12 level without direct cord impingement. The fracture is new compared to the 12/10/2015 chest CT but appears similar to the outside 8/8/2016 lumbar radiograph. There is mild associated increased STIR signal within the T12 vertebra compatible with a subacute course. Vertebral bone marrow signal is otherwise within normal limits without suspicious space-occupying lesions. Thoracic vertebral body heights and disc spaces are otherwise preserved. No epidural collections are identified. The spinal cord displays normal signal and morphology. Minimal degenerative changes are identified within the thoracic spine without additional significant stenosis. A right perineural cyst is incidentally noted T10-11. The paravertebral soft tissues are unremarkable.
Subacute compression fracture of T12 with associated mild retropulsion and mild central canal stenosis.
