%X Chondrosarcomas of thorax are unusual tumors categorized as axial malignancies that also invade and destroy the adjacent bone. These tumors are known to displace soft tissue structures coming in their way without invasion. They destroy adjacent organs violently. In this report, we present a 44-year-old man with a large, expansive mass in the posterior mediastinum invading the spinal canal and epidural space through an intervertebral foramen and displacing the thecal sac. To our knowledge, this is the second case in the literature describing a chondrosarcoma of a rib with dumb-bell-shaped extension to the adjacent intervertebral foramen.
