Abstract Objective: To analyze the MRI findings of solitary fibrous tumor in pelvis. Methods: The MRI features of 5 cases of solitary fibrous tumor in pelvis proved by surgery and pathology were investigated retrospectively. Image characteristics were analyzed. Results: There were 6 lesions in the 5 cases with two lesions in one case. The shape of tumors showed round-like(n=4) and irregular(n=2). ALL lesions were found as well-defined masses. They were mostly hypointense and isotense to the muscle on T1 weighted images and heterogeneous and hyperintense on T2 weighted images. Intra-tumoral flow voids was seen(n=1). After gadolinium administration, the tumors were strongly heterogeneous enhancement(n=3) and mildly heterogeneous enhancement(n=1), one of which was free of contrast enhancement. Conclusion: MRI findings of solitary fibrous tumor in pelvis have some features, preferring to single solitary lesion. MR signals within the tumors were mixed with multiple tubercles, and strongly heterogeneous enhancement after contrast injection. All the findings could suggest the diagnosis of this disease.
