Kim, Ahn, Lee, Paik, Kim, and Hahn: Naso-Sinus Chondrosarcoma: A Case Report

Abstract

Chondrosarcomas are malignant tumors of the cartilage that rarely involve the sinonasal region. Here, we describe a case of histologically verified naso-sinus chondrosarcoma in a 40-year-old female presenting with nasal stuffiness and anosmia. The tumor presented on computed tomography (CT) as an expanding soft tissue mass with bone destruction and pressure erosion. The magnetic resonance images (MRI) of the tumor demonstrated high signals on T2-weighted images with nodular and papillary enhancement along the periphery on T1-weighted images with contrast enhancement. The presence of these typical imaging features should be very helpful in diagnosing chondrosarcoma involving the sinonasal region.
