Well-defined non-enhancing cystic mass in the left posterior mediastinum between the T4 and T10 vertebral levels encasing the descending aorta and displacing the adjacent left lower lobe. The inferior portion and lateral wall of the cyst wall both exhibit localized regions of calcification. The left eighth rib's posterior arch has been destroyed in an expansile, lytic fashion.
Additionally, there is lytic destruction of the left pedicle of the eighth thoracic vertebra, as well as both transverse processes on either side and the posterior vertebral bodies of T7 and T8. Intervertebral extension with left neural foraminal enlargement and perineural fat effacement between T6-T7 and T8-T9.
Multiloculated non-enhancing cystic lesion extending from the chest wall superiorly into the soft tissues of the neck.
No pulmonary cyst is visible.
