Abstract Objective: To investigate MRI features of prostate sarcoma. Methods: Nine patients with prostate sarcoma proved by histology were retrospectively reviewed． The clinical, pathological and radiological data were analyzed． Results: Among 9 patients with prostate sarcoma, adnexal mass existed in 7 patients, nodules existed in 2 patients. Tumors showed isointensity or slight hypointensity on T1WI, slight hyperintensity on T2WI, restricted diffusion on DWI and ADC value was (0.90±0.17)×10-3 mm2/s, which can be seen liquefy and necrosis. After injection of contrast agent, 7 cases showed inhomogeneous enhancement and 2 cases showed homogeneous enhancement; and time-intensity curve showed flow-in pattern in 5 patients, flatbed pattern in 3 patients. Conclusion: MR imaging of prostate sarcoma has certain characteristics, which is helpful for diagnosis, differential diagnosis and guiding treatment plan．
