Cross-sectional imaging of primary thoracic sarcomas with histopathologic correlation: a review for the radiologist.

ABSTRACT

Numerous forms of primary sarcoma can arise from the heart, pericardium, great vessels, lungs, chest wall, and breasts. Magnetic resonance imaging and computed tomography currently play important roles in determining the extent of primary thoracic sarcoma involvement, potential for resectability, and response to therapy. The purpose of this article is to review the various forms of primary sarcoma that may affect the thorax as well as illustrate pertinent cross-sectional radiologic findings with histopathologic correlation.
