Female, 22 years old, with numbness and paralysis. Evaluate for cord compression. Marrow replacing lesions are present in multiple vertebral bodies compatible with metastases. In addition, there is a large tumor within the posterior spinal canal centered at the T8 level which does compress the adjacent spinal cord. Mild epidural tumor extension is suspected at L5 on the right, potentially affecting the exiting L5 nerve root. Scattered paraspinal tumor deposits are also partially visualized.No other large intraspinal lesions are detected without the benefits of IV contrast. Spinal alignment is grossly anatomic. Endplate concavity and slight loss of vertebral body height are seen at T7. Postoperative findings are evident compatible with posterior fossa surgery. A fluid collection in the suboccipital soft tissues may represent a pseudomeningocele.
Multiple osseous lesions are seen compatible with metastases. In addition, there is a large intraspinal tumor centered at the T8 level which does compress the adjacent spinal cord. The patient has already undergone decompressive surgery at the time of this interpretation.
