Objective To investigate the CT imaging characteristics of primary malignant fibrous histiocytoma (MFH) of the liver.Methods The CT, clinical and histopathologic data of 6 patients with MFH were analyzed retrospectively.All the cases were confirmed by surgery and histopathological examinations.Results The tumors were located in the right liver in 4 patients and the left liver in 2 patients.The maximum diameter of the tumors ranged from 5 to 20 cm.All the tumors were unevenly hypodense on plain CT scan.Four tumors had relatively well-defined margins, while 2 tumors had ill-defined margins.After contrast enhancement, the peripheral and internal divisions of the three storiform-pleomorptic MFH showed progressive enhancement.The peripheral and internal divisions of the two inflammatory MFH were obviously enhanced in the arterial phase, and the enhancement decreased in the portal and delayed phases.The hypodense areas of the one myxiod MFH were not enhanced, but the internal floc and divisions were progressive enhanced.On gross pathology, the tumors were round or irregular in shape, most had a complete capsule with multiple surrounding vessels.These findings correlated well with the CT findings.Conclusions CT findings of primary Hepatic MFH have some characteristics.The enhancement pattern is manifested in a fast wash-in and slow wash-out pattern.However, the final diagnosis still relies on histopathological examination.
