      Abstract

      Objective

      The objective of this study was to elucidate the imaging and pathological features of extraskeletal mesenchymal chondrosarcomas (EMCs).

      Methods

      Imaging findings of eight EMC cases were retrospectively analyzed.

      Results

      Soft tissue masses with different patterns of mineralization were found in five cases on computed tomographic scans. On magnetic resonance images, peripherally located EMCs demonstrated mixed signal intensity on T2-weighted images and heterogeneous enhancement with both calcified and noncalcified areas.

      Conclusion

      EMCs exhibited several characteristic imaging features, which when used in combination with the mineralization pattern, enhancement of the calcified area, and signal intensity feature might have diagnostic value for this rare tumor.
