Primary Osteosarcoma of the Spine: a case report
摘要
Primary osteosarcoma of the spine is an uncommon disease. Here we report a 62-year-old female who suffered from progressive chest tightness, dizziness, urinary incontinence, and bilateral lower legs weakness for days. Chest and cervical spine radiographs revealed a large expansile mass with extensive ossifications and adjacent bone destructions in left superior mediastinum and lower neck. Chest CT and spinal MRI scans revealed a large mass with soft tissue components and extensive ossifications involving body, posterior element, paravertebral soft tissue, epidural space, and rib in C7, T1, and T2 levels. The intervertebral disc spaces were spared. Imaging studies are useful for detection, differential diagnosis, and staging of this disease. When a large mineralized tumor involves body and posterior element of the spine in a middle-age person, primary spinal osteosarcoma may be considered in the differential diagnosis.
