Primary angiosarcoma of the chest wall: CT and MR findings.
A surgically confirmed primary angiosarcoma of the chest wall is described. CT showed a right chest wall mass projecting into the thoracic cavity from the right axilla. The tumor was a high density, inhomogeneous-density mass. Invasion to the rib was noted, and calcified foci were demonstrated. A homogenous high-density mass ventral to the chest wall mass was shown. Contrast-enhanced CT did not demonstrate any enhancement. MRI demonstrated a large heterogeneous mass on both T1-weighted images (T1WI) and T2-weighted images (T2WI). Contrast-enhanced axial T1-weighted MR images did not show any enhancement of the mass, but the homogenous mass ventral to the chest wall mass was shown. MRI demonstrated certain characteristic findings of angiosarcoma of the chest wall. Intratumoral hemorrhage with juxtaposed hematoma and aggressive invasion to the surrounding tissue suggest angiosarcoma.
