Imaging manifestations of endometrial stromal sarcoma

Objective:To summarize and analyze the imaging manifestations of endometrial stromal sarcoma(ESS).Methods:The clinical and imaging data of 20 ESS patients confirmed surgically and pathologically were retrospectively analyzed and then compared with pathological data.Results:There were 11 cases of low-grade ESS,1 case of low-grade ESS accompanied with sex cord stromal differentiation,6 cases of high-grade ESS,1 case of low-grade mixed ESS and smooth muscle tumor,and 1 case of undifferentiated ESS.The 20 patients were all with single lesion,including 6 cases of intracavitary growth,7 cases of muscular masses,3 cases of muscular infiltration,3 cases of subserosal tumors,and 1 case of the ectopic tumor.The focal maximum-diameter was(6.18±1.34)cm.There were 14 cases of round-like focus,6 cases with irregular morphology,and 8 cases with clear boundary and 12 cases with unclear boundary.Twelve cases were found with a cobble-stone sign,and eight cases with mucoid degeneration.One case was found with island-like sign alteration,7 cases with peripheral and internal multiple earthworm-like or spiral reinforced vascular shadows in masses,6 cases with peri-tumor T 2WI linear hypointensity outlines,and 6 cases with peri-tumor T 2WI nodular or slight vermicular hyperintensity.The solid components in the all 20 lesions were progressively and persistently enhanced.The enhanced degrees in 15 cases were equal to or higher than the muscular layer,while the enhanced degrees of the other five patients were lower than the muscular layer.Conclusion:The imaging manifestations of ESS display specific characteristics that can help to diagnosis.
