Skeletal metastases

C

linical scenario

Middle aged woman, operated breast carcinoma and multiple post operative chemotherapy cycles presenting with severe low back ache.

CT low back

Findings

Multiple lytic and sclerotic bony lesions are seen involving anterior and posterior elements of dorsal and lumbar vertebrae as well as scattered in the pelvic bones. No secondary spinal canal stenosis.

Discussion

Most common route of spread of infection / neoplasm to the spine is through the vertebral venous plexus. Breast metastasis in general tend to be lytic, once treated / partially treated have a more sclerotic appearance. The importance of pathological bony fractures and secondary spinal canal stenosis needs to be watched out for.
