case_images: MR imagings show a lobulated soft tissue mass from T3 to T5 which extended to the epidural space. There are destructive changes around adjacent bony structures by this mass (A : T2 weighted image, B : T1 weighted image, C and D : Gd-enhanced image).

case_images: Magnetic resonance imaging (MRI) checked at the emergency room showed a lobulated soft tissue mass from T3 to T5, which extended to the epidural space (Fig. 1).
case_images: Computed tomography scans show soft tissue mass on the spinal posterior arch and osteolytic change of the adjacent bony structures.

case_images: Computed tomography scans showed soft tissue mass on the spinal posterior arch and osteolytic change of the adjacent bony structures (Fig. 2).
case_images: A : Gross finding. The resected specimen shows lobulated grayish-white cartilaginous mass with myxoid and cystic change. B : Microscopic finding. The tumor shows bimorphic pattern consisting of low grade chondrosarcoma (on the right) juxataposed of high-grade spindle cell sarcoma (on the left) (hematoxylin eosin stain, x200).
