title: Computed tomography in malignant fibrous histiocytoma.
abstract: The computed tomographic findings in 11 cases of malignant fibrous histiocytoma are discussed. The typical appearance of the eight primary tumors imaged was of a poorly marginated mass with an attenuation coefficient slightly lower than that of normal muscle. Central tumor necrosis was detected in three cases. Three of five abdominal tumors showed involvement of adjacent soft tissue structures, and one demonstrated destruction of adjacent bone. The nonspecific appearance of these tumors prevented their reliable differentiation from other soft tissue sarcomata.
