Magnetic resonance imaging of neck chondrosarcoma: A case report

Chondrosarcoma is a malignancy rarely encountered in the head and neck. The reported prevalence of chondrosarcoma involving the head and neck region has a range of 1-12%. In our case report, we demonstrate a chondrosarcoma of the left lower neck region by means of magnetic resonance imaging. We were not able to show its exact origin and considered the possibility of a rare extraosseous origin. It presented as a slowly growing, painless mass and showed characteristic calcification and high signal intensity on long TR, long TE sequences. It caused left jugular vein compression and left subclavian artery kinking due to mass effect. Histopathologic examination revealed a low-grade mesenchymal myxoid chondrosarcoma. In this study, we review the clinical presentation, imaging features, management, and treatment procedures of these rare tumors.
