Abstract：Objective: To improve the level of imaging diagnosis of intracranial malignant fibrous histiocytoma. Methods: Ten cases of malignant fibrous histiocytoma proved by pathology underwent CT examination before operation. Cerebral angiography and MRI were also performed in 3 and 2 cases respectively. Results: The tumor located in the frontoparietotemporal part in 2 cases, in the frontal part in 2 cases, in the middle cranial fossa in 2 cases, in the parietal part of the brain in 2 cases, in the frontoparietal part in 1 case, and in the frontotemporal part in 1 case. Inhomogeneous density and inhomogeneous enhancement were seen on CT with skull bone invasion in 2 cases. On MR, one tumor showed isointense on T1WI and mixed density on T2WI, while the other showed low density on T1WI and high on T2WI. All the tumors were lobulated. Tumor vessels and compression of the anterior and midddle cerebral arteries were seen in cerebral angiography of the 3 cases. Conclusion: The diagnosis of malignant fibrous histocytoma should be considered when its imaging features are similar with those of malignant meningioma, glioma or metastatic encephaloma with a short history and rapid deteriorated course in the middle aged and the old patients.
