【摘要】：目的:分析肝脏多房环形强化的影像学特征,探讨肝脓肿、肝内胆管细胞癌、肝转移瘤的鉴别诊断要点。方法:回顾性分析31例肝脏病变表现为多房环形强化的影像学特征,其中肝脓肿15例,肝内胆管细胞癌7例,肝转移瘤9例。13例行上腹部CT平扫和三期增强检查,7例行MRI平扫及LAVA多期增强检查,11例同时行CT和MRI检查。结果:3种病变在环壁及分隔的强化征象有差异。肝脓肿环壁及分隔均匀、完整(P0.05),可见病灶缩小征(P0.05)。胆管细胞癌环形强化呈向心性充填(P0.05),或出现肝包膜回缩(P0.05)和扩张胆管壁的局限性增厚。环壁不规则中断或见强化的壁结节,是诊断转移瘤较有价值的征象。结论:肝脓肿、肝内胆管细胞癌、肝转移瘤3种病变各有其影像特点,CT及MR检查对三者的诊断与鉴别诊断有重要价值。
[Abstract]:Objective: to analyze the imaging features of multilocular circular enhancement of liver, and to discuss the differential diagnosis of liver abscess, intrahepatic cholangiocarcinoma and metastatic tumor. Methods: 31 cases of liver lesions with multilocular circular enhancement were retrospectively analyzed. There were 15 cases of liver abscess and 7 cases of intrahepatic cholangiocarcinoma. 9 cases (.13 cases) of hepatic metastases were examined by plain CT scan in upper abdomen and 7 cases by MRI and LAVA multiphase enhancement in 7 cases. Results CT and MRI were performed simultaneously in 11 cases of liver metastases. Results there were differences in the enhanced signs of hepatic septum and circumferential wall among the three kinds of lesions. The wall of the ring is swollen and evenly spaced, The focal narrowing sign P0.05 was seen in intact bile duct cell carcinoma. The circumferential enhancement of cholangiocarcinoma presented concentric filling (P0.05), or the local thickening of hepatic capsule retraction (P0.05) and dilated bile duct wall. The circumferential wall was irregularly interrupted or enhanced mural nodules were observed. Conclusion: liver abscess, intrahepatic cholangiocarcinoma and hepatic metastases have their imaging features respectively. Ct and Mr have important value in the diagnosis and differential diagnosis of the three diseases.
