【摘要】：目的:探討肝良惡性腫瘤引起包膜回縮征的CT和MRI表現(xiàn)及其病理基礎(chǔ)。方法:回顧性分析經(jīng)病理證實(shí)的50例肝良惡性腫瘤肝包膜回縮征的CT和MRI表現(xiàn)及病理特點(diǎn)。通過影像歸檔和通信系統(tǒng)觀察、比較包膜下肝良惡性腫瘤形態(tài)、大小及肝包膜回縮寬度、深度、邊緣情況、肝包膜下是否有積液的異同,顯微鏡下分析腫瘤內(nèi)部及周圍結(jié)構(gòu)、分化程度及纖維組織增生量。結(jié)果:肝惡性腫瘤44例,良性腫瘤6例。良性腫瘤與高、中、低三個(gè)不同分化等級的惡性腫瘤肝包膜回縮邊緣光整或毛糙差異有統(tǒng)計(jì)學(xué)意義(均P0.05)。纖維組織增生量不同的腫瘤肝包膜回縮寬度、深度差異有統(tǒng)計(jì)學(xué)意義(均P0.05)。腫瘤直徑大小與肝包膜回縮寬度、深度呈正相關(guān)(分別r=0.557,0.309,均P0.05)。結(jié)論:肝良惡性腫瘤均可出現(xiàn)肝包膜回縮征,但兩者形態(tài)有差異,與腫瘤大小、分化程度及瘤內(nèi)纖維組織增生程度等密切相關(guān)。
[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.
