Abstract:
Objective To investigate CT appearances of abdominal primary malignant fibrous histiocytoma(MFH).Methods The CT characteristics,clinical features and pathological data of 1 7 patients with MFH proved pathologically were analyzed retrospectively. Results The lesions located in retroperitoneum were 6,in liver were 5,in kidney were 2,in superior mesentery was 1,in greater omentum was 1,in stomach was 1,in ileum was 1.The lesions are oval shape,lobulated,nodule shape,and the size of these lesions were large. 2 cases of MFH located in gastrointestinal tract were slightly low density,and the remaining were uneven high density due to necro-sis.In CT contrast enhanced scan,the solid portion and internal divisions showed progressive or continuous enhancement,and the nec-rosis were not enhanced in MFH located in the retroperitoneum,the greater omentum,the superior mesentery and the liver.MFH in kidney was poorly circumscribed and showed mild progressive enhancement lower than normal renal parenchyma.The stomach and ileum lesions showed uniform and continuous enhancement with normal gastrointestinal mucosa in corresponding parts.Conclusion Imaging features of retroperitoneal MFH were the same as those of interstitial tumors,and most tumors showed features of progres-sive and persistent enhancement,but have different imaging appearances with the malignant lesions in corresponding parts.
