Pinching/kinking of the cervical spinal cord and 1q42.1-44 interstitial deletion. There is persistent considerable narrowing of the upper cervical spinal canal associated with a narrow C1 arch in the anteroposterior dimension. The posterior arch of C1 indents the cervical spinal cord, but there is no evidence of associated signal abnormality within the spinal cord. The atlantoaxial articulation otherwise appears to be intact and the remainder of the cervical spine and imaged upper thoracic spine appears to be unremarkable. The paraspinal soft tissues are unremarkable.
Persistent narrowing of the upper cervical spinal canal associated with a narrow C1 arch in the anteroposterior dimension with indentation of the cervical spinal cord likely represents a developmental anomaly. Please refer to the recent brain MRI report regarding intracranial findings.
