【摘要】：目的探討卵巢纖維瘤的CT及MRI特征。方法回顧性分析經手術病理證實的42例卵巢纖維瘤的CT及MRI資料,21例患者接受CT檢查,26例接受MR檢查,5例同時接受CT和MR檢查,分析其CT和MR特征。結果42例卵巢纖維瘤中單純型29例,變性型11例,特殊型2例。腫瘤均單發(fā),呈圓形、類圓形或分葉狀,邊界清晰40例,部分邊界模糊2例,伴鈣化3例,出血1例。腫瘤最大徑1.4~26.7cm,中位值5.5cm。單純型CT平掃呈等密度,MRI上T1WI及T2WI均呈低信號;變性型CT呈斑片狀、裂隙狀低密度區(qū),T2WI呈高信號,增強掃描腫瘤實質幾乎無強化或僅輕微強化;特殊型1例內見大量出血,1例明顯強化,均誤診為惡性腫瘤。結論卵巢纖維瘤的CT及MRI表現具有一定的特征,但確診仍需依靠病理。
[Abstract]:Objective to investigate the CT and MRI features of ovarian fibroma. Methods the CT and MRI data of 42 cases of ovarian fibroma proved by operation and pathology were retrospectively analyzed. Results in 42 cases of ovarian fibroma, 29 cases were simple type, 11 cases were degenerative type, and 2 cases were special type. The tumors were all single, round, round or lobular, with clear boundary in 40 cases, partial blurring in 2 cases, calcification in 3 cases. Hemorrhage occurred in 1 case. The maximum diameter of the tumor was 1.4 ~ 26.7 cm, with a median value of 5.5 cm. Simple CT plain scan showed low signal intensity on T1WI and T2WI, and degenerative CT showed patchy pattern and high signal intensity in fissure-like low-density area on T1WI and T2WI. Contrast enhanced scan showed little or little enhancement in the tumor parenchyma, and a large amount of hemorrhage was found in 1 case of special type, all of which were misdiagnosed as malignant tumor. Conclusion CT and MRI findings of ovarian fibroma have some characteristics. But the diagnosis still depends on pathology.
