Magnetic resonance imaging findings of extraskeletal mesenchymal chondrosarcoma of wrist: a case report
MetadataShow full item record
Extraskeletal mesenchymal chondrosarcomas (EMC) are high grade malignant tumors that rarely involves wrist. Published reports about them are mostly based on conventional radiography, tomography and conventional magnetic resonance imaging (MRI) findings. We did not recognize any report of dynamic-contrast enhanced MRI so far. Herein, we present dynamic contrast enhanced and Diffusion Weighted MRI findings of a case with extraskeletal mesenchymal chondrosarcoma of the wrist. In conclusion, EMC might show peripheral enhancement at early arterial phase and restricted diffusion on MRI. The knowledge of the imaging spectrum of the EMC might help us suggesting the diagnosis.
