【摘要】：目的探讨成人肠系膜淋巴管瘤的CT表现与病理之间相关性,以提高CT诊断本病的准确率。方法回顾性分析16例肠系膜淋巴管瘤CT与病理表现。结果 16例中起源于小肠系膜10例,大网膜5例,小网膜1例。病变位于腹腔7例,跨腹腔、盆腔6例,盆腔3例。4例单房型淋巴管瘤呈圆形、类圆形;12例多房型淋巴管瘤中类圆形2例,哑铃形2例,爬行式或塑形式生长或呈口袋征8例。囊壁及分隔呈线状或网格状。囊腔内容物呈囊性密度10例,囊实性密度6例;另见含脂肪4例,钙化2例。12例囊壁及间隔呈轻度渐进性强化,囊性或囊实性囊腔不强化。6例病变内见血管穿行,穿行血管不为肿瘤提供血供。16例成人肠系膜淋巴管瘤中囊性淋巴管瘤12例,海绵状淋巴管瘤4例。16例病变中4例没有血管成分,12例含5%~30%不等血管,病变内血管成分与囊腔内囊性或囊实性容物是否强化没有关系。结论爬行式生长,口袋征,血管穿行征,条形脂肪征,增强扫描囊壁及间隔呈渐进性强化而囊腔内囊性或囊实性成分不强化特点相结合,CT检查可以对成人肠系膜淋巴管瘤做出正确诊断。
[Abstract]:Objective to investigate the correlation between CT findings and pathology of mesenteric lymphangioma in adults. Methods CT and pathological findings of 16 cases of mesenteric lymphangioma were analyzed retrospectively. Results among the 16 cases, 10 cases originated from mesentery, 5 cases from omentum and 1 case from small omentum. There were 6 cases of pelvic lymphangioma, 3 cases of single locular lymphangioma, 2 cases of round lymphangioma, 2 cases of dumbbell type lymphangioma, 2 cases of round lymphangioma, 3 cases of pelvic lymphangioma, 3 cases of pelvic lymphangioma, 3 cases of pelvic lymphangioma. There were 8 cases of crawling or plastic growth or pocket sign, 8 cases of cystic wall and septum, 10 cases of cystic density and 6 cases of cystic solid density, 4 cases of fat. Calcification was seen in 2 cases. 12 cases showed slight progressive enhancement of cystic wall and septum. In 6 cases of cystic or solid cystic cavity, vascular perforation was found in 6 cases. Among 16 cases of adult mesenteric lymphangioma, 12 cases were cystic lymphangioma. In 4 cases of cavernous lymphangioma (n = 16), 4 cases had no vascular component, 12 cases had 5% or 30% different blood vessels, and there was no relationship between the vascular composition of the lesion and the enhancement of cystic or solid contents in the capsule. Conclusion the crawling growth, pocket sign, vascular penetration sign, and so on are not related to the enhancement of the cystic or solid contents in the cystic cavity. The characteristics of stripe fat sign, enhancement of cystic wall and septum and no enhancement of cystic or solid components in the capsule can be combined with CT examination to diagnose mesenteric lymphangioma in adults.
