Abstract：Objective: To study the CT and MRI imaging features and pathology of ovarian endometrioid carcinoma (OEC). Method: CT and MRI imaging features of 8 patients confirmed by surgery and pathology were analyzed retrospectively, and compare with the results of surgery and pathology. Results: Five tumors situated in the left and the 3 tumors others in the right ovary, the tumor diameter ranged from 4.5 to 17.5 cm, the average was 9.2 cm. All cases were cystic-solid lesions, irregular and lobulated contour were found in 6 cases, 2 cases were round or oval contour. Seven cases boundary was partial fuzzy, another one was clear. All the cases showed solid component抯 CT value were 37～46 HU in CT plain scan, the average was 41 HU, cystic component抯 CT value were 14～40 HU, the average was 25 HU. On enhanced CT, solid component was moderately enhancement with the CT value about 61～77 HU, the average was 66 HU in the arterial phase. Parenchyma stage value of CT was 65～78 HU, with an average of 71 HU.Underwent MRI, solid components were equisignal and cystic components showed low signal on T1WI. On T2WI imging, solid components showed slightly high signal and cystic component revealed high signal. Enhanced scanning showed moderately enhancement. In 8 cases of OEC complicated with uterine body membrane carcinoma in 2 cases, of which 1 case underwent MRI examination, manifested as irregular thickening of the uterine body membrane, showed T1WI signal, T2WI is slightly high signal intensity, enhancement after enhanced moderately, one case complicated chocolate cyst of ovary in the same side. Conclusion: CT and MRI can show the OEC pathology feature better. Also they can show the boundary of the tumor and block construction and the encroachment of circa-construction clearly, they possess the important qualitation value and provide reasonable treatment plan for clinic.
