摘要

目的：

探讨女性生殖系统淋巴瘤的计算机体层成像（computed tomography，CT）及磁共振成像（magnetic resonance imaging，MRI）特征，以期提高治疗前的诊断准确度。

方法：

回顾并分析13例女性生殖系统淋巴瘤患者的CT及MRI资料，其中7例行MRI平扫+增强扫描，6例行CT平扫+增强扫描。

结果：

13例患者中，弥漫性大B细胞淋巴瘤12例（92.3%），滤泡性淋巴瘤1例（7.7%），其中以卵巢受累最多见（6/13，46.2%），其次是宫颈（5/13，38.5%）和子宫体（2/13，15.4%）。共检查发现14个病灶（MRI和CT各7个），其中1例卵巢淋巴瘤为双侧受累。所有病灶均为实性肿块，64.3%（9/14）的病灶信号或密度相对均质；35.7%（5/14）的病灶边缘可见小囊变区，均见于卵巢淋巴瘤。行CT扫描的7个肿块中，平扫均表现为等密度肿块，内部未见出血及钙化；行MRI扫描的7个肿块中，表现为T1加权成像（T1-weighted imaging，T1WI）等或稍低信号，T2加权成像（T2-weighted imaging，T2WI）以中等信号为主（6/7，85.7%），弥散加权成像（diffusion-weighted imaging，DWI）均呈明显高信号，平均表观弥散系数（apparent diffusion coefficient，ADC）值（0.5250.110）10

/s。增强扫描后，所有肿块均表现为轻-中度强化。

结论：

女性生殖系统淋巴瘤的CT及MRI表现具有一定的特征性，综合其临床和影像学表现术前可精准诊断。

Abstract

Objective:

To investigate the computed tomography (CT) and magnetic resonance imaging (MRI) features of lymphoma of the female reproductive system for improving the diagnostic accuracy.

Methods:

The imaging data of thirteen lymphoma of the female reproductive system patients was retrospective study reviewed

cluding 7 cases underwent MRI plain scan and enhancement scan

6 cases underwent CT plain scan and enhancement scan.

Results:

Among the 13 patients

12 cases (92.3%) were diffuse large B cell lymphoma

and 1 case (7.7%) was follicular lymphoma

with a total of 14 lesions (7 lesions of MRI and 7 lesions of CT). Ovarian involvement was the most common (6/13

46.2%)

of which 1 case was bilaterally affected

followed by the cervix (5/13

38.5%) and the uterine body (2/13

15.4%). All the lesions were solid masses

and 64.3% (9/14) of the lesions had relatively homogeneous signal or density

another 35.7% (5/14) of the lesions had small cystic areas on the edges

all of which were ovarian lymphoma. The 7 lesions on the CT plain scan images all showed iso-density

and there was no bleeding or calcification inside. The 7 lesions showed iso- or hypo-intense signal on T1-weighted imaging (T1WI); T2-weighted imaging (T2WI) mainly showed iso-signal (6/7

85.7%); DWI showed significantly hyperintense signal. And average apparent diffusion coefficient (ADC) value was (0.5250.110)10

-3

/s. Enhanced scanning showed that lesions were mild to moderate enhancement.

Conclusion:

The CT and MRI features of lymphoma of the female reproductive system have characteristics

which can improve the accuracy of preoperative diagnosis.
