目的 观察肝内胆管乳头状肿瘤(IPNB)常规超声及超声造影(CEUS)表现。方法 回顾性分析16例接受腹部常规超声及CEUS检查并经手术病理证实的单发IPNB患者,其中9例伴癌变(癌变组),7例伴中重度异型增生或上皮内瘤变(增生或瘤变组);对比观察2组病灶常规超声及CEUS表现。结果 16个病灶中,11个形态不规则并与肝内胆管相通,10个内部探及点线状血流信号;病灶内部回声可表现为囊性(单房/多房无回声)、囊实性及实性。组间病灶直径、形态、是否与胆管相通及病灶内是否探及血流信号差异均无统计学意义(P均>0.05),内部回声特征差异有统计学意义(P<0.05)。2组病灶CEUS多表现为"快进快出",动脉期均以不均匀增强伴乳头状强化为主,增强模式及动脉期增强形态差异均无统计学意义(P均>0.05)。结论 IPNB常规超声及CEUS表现具有一定特征性。 |

Objective To observe the conventional ultrasound and contrast-enhanced ultrasound (CEUS) manifestations of intraductal papillary neoplasms of bile duct (IPNB). Methods A total of 16 patients with surgical pathology confirmed single IPNB lesion who underwent conventional ultrasound and CEUS were enrolled, including 9 patients with carcinogenesis (carcinogenesis group) and 7 with moderate or severe dysplasia or intraepithelial neoplasia (dysplasia or neoplasia group). Conventional ultrasound and CEUS manifestations of the lesions were observed. Results Among 16 lesions, 11 were irregular and connected with intrahepatic bile duct, 10 were found with dotted and linear blood flow, and the internal echo of the lesions could be cystic (unilocular/multilocular anechoic), cystic-solid or solid. There was no significant difference of the diameter, shape, connection with bile duct nor detection of blood flow signal (all P>0.05), but the internal echo characteristics were significant different between groups (P<0.05). During CEUS, "fast in and fast out" was observed in most lesions, which mainly demonstrated inhomogeneous enhancement with papillary enhancement during arterial phase. No significant difference of enhancement patterns nor arterial-phase enhancement morphology was found between groups (both P>0.05). Conclusion Conventional ultrasound and CEUS manifestations of IPNB had certain characteristics. |
