Magnetic resonance imaging findings of extraskeletal mesenchymal chondrosarcoma of wrist: a case report

Ekstraskeletal mezenkimal kondrosarkomlar (EMK) el bileğini nadiren tutan yüksek gradeli malign tümörlerdir. Literatürde bildirilen yayınlarda çoğunlukla direk grafi, bilgisayarlı tomografi ve konvansiyonel manyetik rezonans görüntüleme (MRG) bulguları esas alınmıştır. Şimdiye kadar literatürde dinamik kontrastlı MRG bulgularını bildiren yayın bulunmamaktadır. Bu olgu sunumunda EMK' un dinamik kontrastlı ve difüzyon ağırlıklı MRG bulgularını sunduk. Sonuç olarak EMK MRG'de erken arteriyel fazda periferal kontrastlanma ve difüzyon kısıtlaması gösterebilir. EMK'nın görüntüleme bulgularının bilinmesi tanının akla gelmesinde önemlidir.

El bileğinde ekstraskeletal mezenkimal kondrosarkomun manyetik rezonans görüntüleme bulguları: olgu sunumu

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.
