There is mild left maxillary sinus mucosal thickening.Cervical Spine: The spinal cord displays normal signal and morphology. There is no evidence of pseudomeningocele. 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.
