【摘要】：目的:探讨肝良恶性肿瘤引起包膜回缩征的CT和MRI表现及其病理基础。方法:回顾性分析经病理证实的50例肝良恶性肿瘤肝包膜回缩征的CT和MRI表现及病理特点。通过影像归档和通信系统观察、比较包膜下肝良恶性肿瘤形态、大小及肝包膜回缩宽度、深度、边缘情况、肝包膜下是否有积液的异同,显微镜下分析肿瘤内部及周围结构、分化程度及纤维组织增生量。结果:肝恶性肿瘤44例,良性肿瘤6例。良性肿瘤与高、中、低三个不同分化等级的恶性肿瘤肝包膜回缩边缘光整或毛糙差异有统计学意义(均P0.05)。纤维组织增生量不同的肿瘤肝包膜回缩宽度、深度差异有统计学意义(均P0.05)。肿瘤直径大小与肝包膜回缩宽度、深度呈正相关(分别r=0.557,0.309,均P0.05)。结论:肝良恶性肿瘤均可出现肝包膜回缩征,但两者形态有差异,与肿瘤大小、分化程度及瘤内纤维组织增生程度等密切相关。
[Abstract]:Objective: to investigate the CT and MRI features and pathological basis of capsule retraction caused by liver benign and malignant tumor. Methods: the CT and MRI findings and pathological features of 50 cases of liver benign and malignant tumor with hepatic capsule retraction were retrospectively analyzed. The morphology, size, width, depth, margin of hepatic capsule retraction, similarities and differences of subcapsular effusion were compared by image archiving and communication system. The internal and peripheral structures of the tumor were analyzed under microscope. Degree of differentiation and proliferation of fibrous tissue. Results: there were 44 cases of hepatic malignant tumor and 6 cases of benign tumor. There were statistically significant differences between benign tumor and high, middle and low differentiation grade malignant tumor liver capsule retraction margin or rough (P0.05). There were significant differences in the width and depth of hepatic capsule retraction with different fibrous tissue proliferation (P0.05). There was a positive correlation between the diameter of the tumor and the width and depth of the hepatic capsule (r = 0.557 or 0.309, respectively, P0.05). Conclusion: hepatic capsule retraction sign can be found in both benign and malignant tumors, but there is a difference between them, which is closely related to the tumor size, differentiation degree and the degree of fibrous tissue proliferation in the tumor.
