摘要
目的:分析胆管细胞癌(PICC)影像表现及误诊原因,提高对周围型胆管细胞癌的CT诊断水平及鉴别诊断方法。方法:回顾性分析经病理证实的周围型肝内胆管细胞癌8例,术前均经64排螺旋CT扫描并误诊,分析影像特征及误诊原因。结果:8例中,误诊为肝囊肿2例,血管瘤1例,肝脓肿3例,原发性肝细胞癌1例,转移瘤1例。8例病例平扫均呈低密度灶,边界模糊;增强扫描动脉期边缘不均匀环状强化5例,无明显强化3例;多病灶3例;延迟呈渐进性强化7例;边缘分叶征7例;胆管包绕征7例;肿块内条索状、结节状高密度影4例;近端胆管扩张4例;包膜凹陷征1例。AFP均为阴性;CA199阳性7例,R-GT升高4例。结论:肝周围型胆管细胞癌CT表现具有特征性;增强扫描加延迟扫描有助与提高病变诊断准确率。
objective： To analyse the bile duct cell cancer （usm） video presentation, and misdiagnosis reasons, increase of peripheral bile duct carcinoma of CT diagnosis and differential diagnosis methods. Methods： Confirmed by pathology were retrospectively analyzed of peripheral intrahepatic bile duct cell cancer 8 cases, preoperative 64 row spiral CT scan and misdiagnosis, analysis of image characteristics and misdiag- nosis reasons. Results：In 8 cases, 2 cases were misdiagnosed as liver cyst, cavernous hemangioma 1 case, hepatic abscess （3 cases）, primary llver cell carcinoma 1 case, and metastases in 1 case. 8 cases flat sweep is low density foci, fuzzy boundaries; Uneven edges of annular arteri- al enhancement scan in 5 cases, no obvious reinforcement （3 cases）; Multifocal in 3 cases; Delay a gradual strengthening in 7 cases; Edge points Ye Zheng 7 cases; Bile duct surrounding the drafts in 7 cases; Within a funicular, 4 cases of nodular high density shadow, 4 cases of proximal bile duct expansion; Coated sag in 1 case. AFP negative; - CT positive CA199 positive in 7 cases, 4 caseS. Conclusion： Peripheral hepatic bile duct carcinoma CT shows its characteristics; Enhanced scanning and delay scan helps to improve disease diagnosis accuracy.
