目的探讨CT与MRI对伴有黏液变性巨大子宫肌瘤的诊断价值。方法选取2013年7月-2016年8月医院妇科收治的78例经手术病理证实的巨大子宫肌瘤患者,均行CT及MRI检查,并对影像学特征进行对照分析。结果 78例患者中有51例单发,27例多发,肿瘤最长径(21.39±4.20)cm,15例位于浆膜下,32例位于肌壁间,12例位于宫颈肌部,19例位于骶前间隙,CT显示等密度肿瘤46例,混杂密度肿瘤32例,手术病理结果分别对应子宫肌瘤伴区域黏液变性、子宫肌瘤伴广泛黏液变性,MRI示T1WI/T2WI以等信号为主者45例,T1WI等信号、T2WI混杂信号者12例,其余呈T1WI低信号、T2WI混杂信号。CT显示等密度肿瘤46例、混杂密度肿瘤32例。结论 CT在巨大子宫肌瘤黏液变性诊断方面具有突出优势,而MRI则有助于鉴别巨大子宫肌瘤来源,联合使用两种检查方法可提高诊断准确率。
Objective To investigate the diagnostic value of CT and MRI in the diagnosis of giant uterine fibroids with mucoid degeneration. Methods From July 2013 to August 2016, 78 patients with giant uterine fibroids confirmed by surgery and pathology underwent gynecological examinations in our hospital. All patients underwent CT and MRI examinations. The imaging features were analyzed comparatively. Results Of the 78 patients, 51 were single and 27 were multiple. The longest tumor diameter was (21.39 ± 4.20) cm. Fifteen were located in the subserosus, 32 in the muscular wall, 12 in the cervical muscular and 19 in the cervical Presacral space, CT showed that 46 cases of isodense density tumors, mixed density tumors in 32 cases, surgical pathology results corresponding to myoma with regional mucinous degeneration, uterine fibroids with extensive mucinous degeneration, MRI showed T1WI / T2WI with equal signal 45 cases, T1WI and other signals, T2WI mixed signal in 12 cases, the rest were T1WI low signal, T2WI mixed signal. CT showed 46 cases of equal density tumors, mixed density tumors in 32 cases. Conclusion CT in the diagnosis of mucinous degeneration of great uterine fibroids have outstanding advantages, while MRI is helpful to identify the source of huge uterine fibroids, the combined use of two examination methods can improve the diagnostic accuracy.
