Metastatic thyroid Ca, on therapy, eval for dz, compare to previous with measurements. Thoracic: Stable appearance of the enhancing lesion in the T5 vertebral body, measuring 15 x 9 mm in the sagittal plane, unchanged. Enhancing and slightly expansile lesions in the left transverse process and pars interarticularis of T5 and T6 appear similar to prior. Again seen are postsurgical changes at T10-T12 related to left lateral fusion and partial corpectomy of T11. There is persistent diffuse abnormal marrow signal in the T11 vertebral body. Kyphotic angulation of the thoracic spine is seen centered at T11. Abnormal fatty marrow replacement in the lower thoracic spine appears similar to prior, likely secondary to post radiation changes. No definite new lesions are identified and there is no epidural disease.Lumbar: Stable appearance of the enhancing lesions at L2, L3, and L5. The reference L5 lesion measures 18 x 16 mm in the axial plane, unchanged. Similar to the thoracic spine, there is abnormal fatty replacement of the vertebral bodies, compatible with previous radiation. No new lesions are identified and there is no epidural disease. Stable mild degenerative changes are again seen without significant spinal canal or foraminal stenosis.
1.No significant change in the appearance of multiple osseous metastatic lesions involving the thoracolumbar spine.2.No new lesions are identified.3.No evidence of epidural disease or significant spinal canal or neural foraminal narrowing.
