 Partially imaged on the sagittal scout sequence is unchanged mildly low-lying cerebellar tonsils extending 3 mm below the foramen magnum with a slightly pointed morphology. There is also mild retroflexion of the dens. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord displays normal signal and morphology with the conus terminating at T12-L1. There is no evidence of spinal mass or abnormal enhancement. The paravertebral soft tissues are unremarkable.
1.No evidence of thoracic or lumbar spine abnormality. 2.Partially imaged, unchanged, foramen magnum crowding secondary to dens retroflexion, and mildly low lying cerebellar tonsils that have a slightly pointed morphology.
