Aneurysmal bone cysts experience both cystic and filled in components, with the lat- ter enhancing. The cystic components frequently repress blood disgrace products, with fluid fluid levels aid. There is an expansile mountain of the spinous prepare (of this cervical vertebra), with weirdo consequential signal energy on the T2-weighted scan and prominent enhancement. This expansile kind neoplasm consists of blood-filled spaces, with enhancement introduce in crowded por- tions of the lesion.
