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).

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).
Computed tomography scans show soft tissue mass on the spinal posterior arch and osteolytic change of the adjacent bony structures.

Computed tomography scans showed soft tissue mass on the spinal posterior arch and osteolytic change of the adjacent bony structures (Fig. 2).
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).
