Male, 53 years old, with metastatic thyroid cancer, follow-up exam. Thoracic: An enhancing lesion within the left aspect of the T5 vertebral body measures approximately 15 x 9 mm and not significantly changed. Lesions within the left transverse process and pars interarticularis of T5 and T6 are also unchanged.Left lateral fusion of T10-T12 is again seen with partial corpectomy at T11 and placement of a strut graft. The residual T11 vertebral body continues to show diffuse abnormal marrow signal without significant change. Kyphotic angulation of the thoracic spine is seen centered at T11.No new lesions are seen. No significant epidural disease is seen. No significant spinal canal stenosis is seen.Fatty marrow replacement in the lower thoracic spine likely represents postradiation change. Failure of fat suppression is also seen in the lower thoracic spine on postcontrast fat-suppressed images.Lumbar: Enhancing lesions on the right at L2, on the left at L3, and on the left at L5 show no significant interval change. For reference, the L5 lesion continues to measure 18 x 16 mm.The background marrow remains fatty replaced compatible with prior radiation. No new lesions are seen. No significant epidural disease extension is detected. The spinal canal remains patent.Mild degenerative changes are again seen without significant spinal canal or foraminal stenosis.
1. No significant change in multiple osseous metastatic lesions involving the thoracic and lumbar spine. No new lesions. 2. No evidence of epidural disease or spinal canal or neural foraminal narrowing.
