OBJECTIVE: The purpose of this study was to describe the radiologic and
pathologic features of pulmonary carcinosarcoma in three patients.
CONCLUSION: The tumors measured 9-14 cm in diameter, had inhomogeneous
contrast enhancement, and in two cases had invaded the mediastinum or chest
wall extensively. Carcinosarcomas are rare tumors that tend to be large,
necrotic, enhancing, and locally invasive.
