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。
Objective To investigate the correlation between CT appearance and pathology in adult mesenteric lymphangioma in order to improve the accuracy of CT diagnosis of this disease. Methods A retrospective analysis of 16 cases of mesenteric lymphangioma CT and pathological findings. Results Of the 16 cases, 10 cases originated from the small mesentery, 5 from the omentum and 1 from the omentum. 7 cases of lesions located in the abdominal cavity, transabdominal, pelvic 6 cases, pelvic 3 cases. 4 cases of single-chamber lymphangioma were round and round; 12 cases of multilocular lymphangioma were round in 2 cases, dumbbell in 2 cases, creeping or plastic growth or pocket sign in 8 cases. Wall and the separation is linear or grid-like. Cystic contents were cystic density in 10 cases, cystic densities in 6 cases; see also containing 4 cases of fat, calcification in 2 cases. 12 cases of cyst wall and the interval was mild progressive enhancement, cystic or cystic solid cyst is not enhanced. 6 cases of vascular lesions seen in the line, through the blood vessels do not provide blood supply for the tumor. 16 cases of adult mesenteric lymphangioma in cystic lymphangioma in 12 cases, 4 cases of cavernous lymphangioma. Of the 16 lesions, 4 had no vascular components and 12 had 5% to 30% of the vessels. The vascular contents in the lesions were not related to the cystic or cystic solid contents in the cysts. Conclusion Creep growth, pocket sign, vascular perforating syndrome, steatosis, enhanced cyst wall and progressive enhancement of cyst and cystic cyst or cystic solid composition is not combined with enhanced features, CT examination of adult mesentery Lymphoma to make the correct diagnosis.
