Computerized Tomography Findings of a Sternal Osteosarcoma

Malignant bone tumors of the chest wall and sternum are more rare because most bone tumors occur in the long bones or joints.Osteosarcoma (OS) is a malignant bone tumor that occurs in the second or third decade of life. The men/women ratio is about 3:2 and half of the tumors occur near the knee. The most commonly occurring malignant tumor in sternum is chondrosarcoma and occurrence of osteosarcoma in sternum is extremely rare (1,2). For the radiological examination x-ray, computerized tomography (CT) scanning and magnetic resonance imaging (MRI) can be used. Among these the CT scanning is a valuable diagnostic method as it shows the peripheral soft tissue component and the intrathoracic spread of the tumor. In this report, we present the CT findings of a case with sternal OS.
