Mesenchymal chondrosarcoma arising from primitive mesenchymal cells is a distinctive type of chondrosarcoma that exists in both skeletal and extraskeletal forms. The tumor is composed of undifferentiated cells with focal areas of cartilaginous or chondroid matrix. An extremely rare case of mesenchymal chondrosarcoma of the anterior and middle ethmoid sinuses in a 16-year-old girl is presented. Magnetic resonance imaging provided more anatomic information about the tumor than computerized tomography and aided in surgical planning.
源自原始间充质细胞的间叶性软骨肉瘤是一种独特类型的软骨肉瘤，有骨骼和骨骼外两种形式。肿瘤由未分化细胞及局灶性软骨或类软骨基质组成。本文报告了一名16岁女孩前筛窦和中筛窦发生间叶性软骨肉瘤的极其罕见病例。磁共振成像比计算机断层扫描提供了更多关于肿瘤的解剖学信息，并有助于手术规划。
