【摘要】：目的探討腹膜間皮瘤(PM)的CT表現(xiàn)及鑒別要點(diǎn)。方法回顧性分析經(jīng)病理和(或)免疫組織化學(xué)證實(shí)的18例PM的CT和臨床資料。結(jié)果 18例PM的CT表現(xiàn)為:(1)惡性PM 13例,其中彌漫型10例,局限型3例;10例彌漫型表現(xiàn)為腹膜、腸系膜及網(wǎng)膜不規(guī)則增厚,9例伴腹腔積液;4例腹膜、腸系膜呈腫塊狀、斑片狀增厚,3例腸系膜、網(wǎng)膜呈"餅狀"、"污垢狀"增厚,3例腹膜呈多發(fā)小結(jié)節(jié)狀增厚;6例增強(qiáng)掃描后增厚的腹膜、腸系膜及網(wǎng)膜明顯強(qiáng)化;3例局限型表現(xiàn)為腹腔巨大孤立性囊實(shí)性腫塊,以囊性為主伴壁結(jié)節(jié),2例增強(qiáng)后實(shí)性成分輕中度強(qiáng)化;(2)良性囊性PM 3例,表現(xiàn)為單囊性或多囊性液性密度腫塊,囊壁薄而均勻,2例增強(qiáng)掃描后無(wú)強(qiáng)化;(3)高分化乳頭狀PM 2例,表現(xiàn)為附件區(qū)不規(guī)則囊實(shí)性腫塊,1例伴鈣化灶及少量盆腔積液,1例增強(qiáng)掃描后實(shí)性部分輕中度強(qiáng)化。結(jié)論 PM的CT表現(xiàn)多樣,惡性者有一定的相對(duì)特征性,結(jié)合臨床資料和鑒別診斷,綜合分析,可以提高本病的診斷水平。
[Abstract]:Objective to investigate the CT findings and differential features of peritoneal mesothelioma (PMN).Methods CT and clinical data of 18 cases of PM confirmed by pathology and / or immunohistochemistry were analyzed retrospectively.Results the CT findings of 18 cases of PM were as follows: (1) malignant PM (n = 13), including diffuse type (n = 10), localized type (n = 10), diffuse type (n = 10), irregular thickening of mesentery and omentum (n = 9) with peritoneal effusion (n = 4).The mesenteric membrane was thickened in 3 cases with macular thickening, the omentum was "cake shaped", and the peritoneum was thickened in 3 cases with "fouling" in 3 cases with multiple small nodule thickening in 6 cases with peritoneal thickening after enhanced scanning.In 3 cases of mesenteric and omentum enhancement, 3 cases were characterized by giant solitary cystic solid mass in abdominal cavity, 2 cases with cystic mass with wall nodule, 2 cases with mild and moderate enhancement of solid component after enhancement) 3 cases with benign cystic PM.The findings were single cystic or polycystic fluid density mass, thin and homogeneous cystic wall in 2 cases, without enhancement in 2 cases, and highly differentiated papillary PM in 2 cases.The findings included irregular cystic solid mass in adnexal region with calcification in 1 case and a small amount of pelvic effusion in 1 case.Conclusion the CT findings of PM are diverse and malignant patients have some relative characteristics. Combining with clinical data and differential diagnosis and comprehensive analysis, the diagnostic level of PM can be improved.
