目的：探讨成人肝脏胆管错构瘤的影像学表现，以提高对本病的认识。方法回顾性分析5例经手术、病理证实的肝内胆管错构瘤的影像学表现。对所有患者均行磁共振成像（MRI）平扫、磁共振胰胆管造影（MRCP）、增强扫描，并穿刺活检病理证实。结果 T1WI病变呈低于肝实质的信号，呈多发，沿血管胆管树分布， T2WI病灶显示清楚，呈明显的高信号，在MRCP序列上，多数病变显示为高信号，与T2WI比较，显示的病变数量有所减少。MRCP显示肝内多发类囊状高信号病变，与可见的胆管树不相通。增强扫描示各期病灶无强化，在增强扫描60 s，3 min肝实质明显强化，小囊状信号未见明显强化，形成明显的对比。结论成人肝内胆管错构瘤在影像学上无特征性表现，类似于肝转移瘤、肝脓肿、肝海绵状血管瘤等常见的肝囊性占位病变。
目的：探討成人肝髒膽管錯構瘤的影像學錶現，以提高對本病的認識。方法迴顧性分析5例經手術、病理證實的肝內膽管錯構瘤的影像學錶現。對所有患者均行磁共振成像（MRI）平掃、磁共振胰膽管造影（MRCP）、增彊掃描，併穿刺活檢病理證實。結果 T1WI病變呈低于肝實質的信號，呈多髮，沿血管膽管樹分佈， T2WI病竈顯示清楚，呈明顯的高信號，在MRCP序列上，多數病變顯示為高信號，與T2WI比較，顯示的病變數量有所減少。MRCP顯示肝內多髮類囊狀高信號病變，與可見的膽管樹不相通。增彊掃描示各期病竈無彊化，在增彊掃描60 s，3 min肝實質明顯彊化，小囊狀信號未見明顯彊化，形成明顯的對比。結論成人肝內膽管錯構瘤在影像學上無特徵性錶現，類似于肝轉移瘤、肝膿腫、肝海綿狀血管瘤等常見的肝囊性佔位病變。

Objective To investigate the imaging performance of the adult intrahepatic bile duct hamartoma, in order to improve the understanding of this disease. Methods Retrospective analysis of 5 cases confirmed by surgery and pathology of intrahepatic bile duct hamartoma imaging findings. All patients underwent magnetic resonance imag-ing(MRI) scanning, magnetic resonance cholangiopancreatography (MRCP), enhanced scanning, 5 cases of this group were confirmed by the biopsy. Results The signal of T1WI lesion was lower than the liver parenchyma and the le-sions were multiple along the vascular biliary tree. T2WI lesion signal was clear and high. In the MRCP sequence, the majority of lesions showed high signal compared with T2WI, and the number of lesions decreased. The MRCP showed the multiple intrahepatic cystic high signal which was not connected with visible biliary tree. In the enhanced scan-ning of lesion, there were no enhancement of the lesion in every stage. However, the liver pavenchyma significantly enhanced in 60 s and 3 min after enhanced scanning, and the small cystic signals was not significantly enhanced. Conclusion Adult intrahepatic bile duct hamartoma has no characteristic radiographic manifestations, which is simi-lar to the common liver cystic lesions of the liver metastases, liver abscess, hepatic cavernous hemangioma and so on.
