目的:分析CT及MRI对巨大子宫肌瘤黏液变性的表现特征,探究其在巨大子宫肌瘤黏液变性中的诊断价值。方法:选取2013年6月至2015年9月期间我院收治的经过病理证实的40例巨大子宫肌瘤患者作为研究对象,对比分析巨大子宫肌瘤黏液变性的CT表现和MRI表现,并将CT、MRI结果和病理结果进行对照。结果:所有患者的肿瘤均位于盆腔内,肿瘤的直径大小在10-30cm,平均大小在(23.1±2.4)cm;肌瘤CT平扫密度可以将巨大子宫肌瘤分为等密度肿瘤和混杂密度肿瘤,应用MRI检查可以有效显示肿瘤和子宫的关系,将其分为三种:一:肌瘤在T1W1和T2W1上主要为等信号,内部可以看见散在的小斑片,表现为T1低信号,T2高信号的病灶;二:肌瘤在T1W1的等信号,T2W1等高混杂信号;三:肌瘤在T1W1为等(或者稍低)信号,T2W1为高低混杂信号,主要分布在肿瘤内。结论:CT对巨大子宫肌瘤黏液变性具有诊断意义,MRI对巨大子宫肌瘤黏液变性具有鉴别意义,联合应用可以提高诊断的准确率。
Objective: To analyze the characteristics of mucocutaneous degeneration of giant uterine fibroids by CT and MRI, and to explore its diagnostic value in mucinous degeneration of huge uterine fibroids. Methods: Forty cases of giant uterine fibroids confirmed by pathology in our hospital from June 2013 to September 2015 were selected as the study object, CT features and MRI findings of giant uterine fibroids were compared and analyzed. CT MRI results and pathological results were compared. Results: The tumors of all patients were located in the pelvic cavity. The diameter of the tumors was between 10 and 30 cm and the average size was (23.1 ± 2.4) cm. The CT scan density of fibroids could divide the large uterine fibroids into isodense tumors and mixed densities Tumor, the application of MRI examination can effectively show the relationship between the tumor and the uterus, which is divided into three types: one: T1W1 and T2W1 fibroids mainly for the same signal, the internal scattered small patches can be seen in the performance of T1 low signal, T2 high signal lesions; second: fibroids T1W1 equal signal, T2W1 contour mixed signal; third: fibroids T1W1 equal (or slightly lower) signal T2W1 high and low mixed signals, mainly located in the tumor. Conclusion: CT is of great significance in diagnosing mucocutaneous degeneration of huge uterine fibroids. MRI is of great significance for mucinous degeneration of huge uterine fibroids. Combined application can improve the diagnostic accuracy.
