     3.2 原发性弥漫性结节型肝癌的病理特点及CT表现

    对于原发性弥漫性结节型干肝癌患者,其临床病理特点主要为小结节广泛分布于肝内,且结节大小及分布规律较为均匀,一般不存在巨快结节,直径常位于10 mm内[9];因而在行CT平扫时其主要表现为肝脏密度分布不均,且分布均匀的小结节边缘不清晰、模糊,主要呈现为等密度或低密度,另外还可以发现严重程度不一的肝硬化[10],另外还可以清晰观察到门静脉癌栓形成,本文26例患者中,其中21例患者均为肝内门静脉癌栓,占80.77%,其中4例合并肝外门静脉癌栓,由此可知,原发性肝癌晚期患者,其发生门静脉癌栓的可能性非常高,而这一研究结果也基本与郭明智[11]报道保持一致。

    3.3 多发结节型转移性肝癌的病理特点及CT表现

    多发结节型转移转移肝癌有着较为独特的病理特点,而这一特点也使得其CT扫描表现具备较为明显的特异性。人体任何一部位在遭遇病变后,其所生长的恶性肿瘤都可以通过门静脉、肝动脉及淋巴途径向肝脏等器官进行转移,因此其CT表现较为特殊[12]。如消化系统癌变后,生长的恶性肿瘤会通过门静脉途径转移到肝脏,而转移性肝癌的数目、肿瘤大小、形态等存在多变性,如单个病灶、多个结节病灶等[13]。本文中选取18例患者均为多发结节型转移性肝癌,经CT扫描后,其表现特点主要为:平扫时,可以发现肝内多个低大小不等类圆形结节样,为多发性、大小不一水样密度、等样密度、混杂密度样结节,且结节周边界限较为模糊,其密度改变可观察到病灶最外层明显呈现略低密度,而中间薄层呈现为等密度,内层为等样密度、混杂密度样结节影;在增强扫描后,可以发现肝实质密度明显高于最外层低密度,且最外层并未得到明显强化,但边缘薄层却呈环状强化,也就是临床所说的“牛眼征”,18例患者中,14例患者为“牛眼征”,占77.78%,这说明该征发生率较高,这可能与肝脏转移肿瘤对周边肝脏组织的压迫、侵润以及形成的水肿有关,也可能因为肿瘤坏死产生。

    3.4 肝癌的其他诊断方式

    肝癌的临床鉴别及诊断,并非仅仅CT扫描一种,如超声、MRI等检查方式都能对肝癌的临床鉴别和诊断提供高价值的参考资料。独建库等[14]研究显示,采取多普勒彩色超声诊断仪对肝癌患者进行检查,其扫描结果同样具备一定的特异性。

    综上所述,原发性弥漫结节型肝癌患者和多发结节型转移性肝癌患者CT表现均具备较为明显的临床特征和特异性,通过联系患者的临床资料及其他检测结果,有利于病症的鉴别和确诊。

    【Abstract】 Objective:Discussion and analysis of primary diffuse nodule with multiple nodules of liver cancer patients with metastatic liver cancer CT manifestations and diagnostic value, and summarizes the experience.Method:Selection from January 2011 to December 2013 in our hospital diagnosis and treatment of 26 patients with primary diffuse nodular liver cancer and 18 cases of multiple nodules in patients with metastatic liver cancer as the research object,the clinical data of the study object and CT scans for collection and analysis,summarized the experience in diagnosis.Result:Finishing found that primary diffuse nodules in patients with cancer of the liver CT performance main characteristics as follows:scan or enhanced scanning,liver lobe volume ratio were significantly abnormal,disproportionate.Scan,each lobe liver isodensity or diffuse low density nodules,and the fuzzy boundaries.Enhanced scan,each part of the liver lesion does not appear obviously improved or show cricoid improved.For multiple nodules in patients with metastatic liver cancer,the CT performance mainly has the following characteristics:scan,all of right hepatic lobe, multiple mixed density nodules,and the boundary was not clear.Edge enhancement scan,lesions were apparent annular enhancement,but the outermost displayed as low density, and no obvious reinforcement, "bull’s-eye" and "hua" portal vein tumor patients in 14 cases and 2 cases in turn.Conclusion:Primary diffuse nodules in patients with liver cancer and multiple nodules in patients with metastatic liver cancer CT has more obvious clinical features and specificity,by contacting the patient’s clinical data and test results,to identify and diagnose disease.
