52-year-old male patient with metastatic thyroid cancer. Please compare to prior examination. Thoracic spine: An enhancing lesion in the left anterior aspect of the T5 vertebral body is unchanged from the prior exam measuring approximately 13 x 9 mm on axial images. The lesion is associated with mild superior endplate concavity, also unchanged.Lesions within the left transverse process and pars interarticularis of T5 and T6 also show no significant interval change.Instrumented fusion of T10 through T12 is again seen. The T11 vertebral body has been at least partly resected and replaced by an orthopedic spacer device. The residual vertebral body remains compressed demonstrating diffusely abnormal signal characteristics compatible with metastatic involvement. Findings are stable.No new lesions are seen. No epidural disease extension is identified. The spinal canal is not significantly narrowed. Mild kyphotic angulation and scoliosis centered at T11 are stable.T1 shortening in the thoracic and lumbar spine is likely related to prior radiation. Increased signal within the T9 and L1 vertebral bodies on fat-suppressed T1 post contrast images is at least in part artifactual and due to metal related failure of fat suppression.Lumbar:Lesions within the right aspect of the L2 vertebral body, the left aspect of the L3 vertebral body, and the left aspect of the L5 vertebral body are unchanged. For reference, the L5 lesion measures 18 x 16 mm. A small nonspecific lesion along the inferior endplate of L4 is also unchanged.No new lesions are detected. No epidural disease extension is identified. The spinal canal and neural foramina remain patent. The conus and cauda equina are normal.
Stable exam with no evidence of new or progressive metastatic disease in the thoracic or lumbar spine.
