摘要
目的总结肝硬化并发原发性肝癌合并肝囊肿(HHC)患者的影像学特征。方法分析106例HHC患者的上腹部增强CT,观察其临床特征、囊肿的直径、所在肝段、CT值等,并以109例无合并原发性肝癌的肝硬化肝囊肿患者作为对照。结果与无合并肝癌的对照组比较,HHC组的年龄偏大(P=0.039)、肝炎合并比例高(P=0.036)且肝硬化病程长(P=0.043);HHC组的囊肿为2～9个,而对照组为1～5个,两组的囊肿总数差异具有统计学意义(P<0.05);HHC组患者囊肿直径3～11 cm,而对照组为2～6 cm,两组的囊肿直径差异具有统计学意义(P<0.05);对照组的CT值多在15 Hu以内,而HHC组约半数超过15 Hu,两组差异具有统计学意义(P<0.05);HHC组的囊肿病灶总体以右半肝为主,尤其是S6段及S8段偏多,左半肝则以S3段偏多;对照组患者囊肿病灶以左半肝为主,尤其S3及S4偏多,两组的囊肿肝段分布差异具有统计学意义(χ~2=2.572,P=0.011)。结论年龄、肝炎、肝硬化可能是原发性肝癌患者合并肝囊肿的危险因素;多发、右叶多见、直径大、易发生坏死,是HHC患者的囊肿形态学特征。
Objective To summarize the imaging features of hereditary hepatic carcinoma（HHC） combined with cirrhosis in patients with hepatic cysts. Methods 106 HHC cases were included as the HCC group and undertook upper abdominal enhanced CT examination, while 109 cirrhosis patients with hepatic cysts were included as the control group. CT findings,including HHC＇s clinical features, diameter of the cyst, hepatic segment where cysts locate, CT value, were observed and compared with that of the control group. Results Compared with the control group, patients in HHC group were significantly older（P=0.039） and had a higher proportion of hepatitis（P=0.036）and longer course of cirrhosis（P=0.043）; he total number of cyst differed significantly between HHC group and the control group（2-9 in HHC group, 1-5 in control group）（P=0.036）;the cyst diameter differed significantly between two groups, with it being 3-11 cm in HHC group and 2-6 cm in the control group（P=0.041）; the difference of CT value between two groups was significant, with it being within 15 hu in the control group and over 15 hu in about half of the HHC group（P=0.023）; the segment of cyst distribution differed significantly between the two groups, as the majority of cysts in HCC group located in the right liver, especially in the S6 and S8 section, while that of the control group located in the left half liver, especially in the S3 segment（χ-2=2.572, P=2.572）. Conclusion Age, hepatitis, cirrhosis of the liver may be risk factors for hepatic cysts in HCC patients. The morphological features of hepatic cysts in HCC patients include multiple lesions, frequent occurrence in the right lobe see, large diameter, and high susceptibility to necrosis.
