Q

What are focal decreases in vertebral opacity indicative of?

A

Most likely neoplasia, less likely infection
One vertebrae = primary neoplasia

Primary neoplasia

Primary neoplasia

Focal increase in vertebral opacity

What are differentials for focal increase in vertebral opacity?

Chronic compression fx Osteomyelitis Neoplasia Possible degenerative change

Neoplasia

What are the differentials for multifocal decrease in vertebral opacity?

Metastasis (osteosarcoma, carcinoma) Multiple myelome

Multifocal decrease in vertebral opacity

Normal spine

Mets to caudal lumbar spine (periosteal rxn on ventral aspect vertebral body) *When seen, look for primary tumor elsewhere*
