类癌是小肠Treitz韧带远端常见的原发恶性肿瘤且常侵犯肠系膜。作者对12年中29例诊断明确的肠系膜类癌进行了回顾性研究(其中CT资料29例、组织学资料21例,可供分析)。男19例,女10例,年龄35～92岁。肿瘤位于空肠3例,回肠17例,空回肠2例,回盲部2例,3例未确定小肠的具体部位,2例原发部位不明。27例单发肿瘤中12例单发,15例多发。肉眼肿瘤大小为0.2～0.6cm,平均2cm。CT评价肠系膜肿块的大小、边缘、密度、放射状条索、钙化和小肠壁厚度。放射状条索分轻度(细条<10个)、中度(细条
Carcinoid is a common primary malignancy in the distal part of the intestinal Treitz ligament and often invades the mesentery. The authors retrospectively studied 29 cases of mesenteric carcinoid tumors diagnosed in 12 years (29 cases of CT data and 21 cases of histological data were available for analysis). Male 19 cases, female 10 cases, aged 35 to 92 years old. The tumors were located in the jejunum in 3 cases, in the ileum in 17 cases, in the jejunum in 2 cases, in the ileocecal area in 2 cases, and in 3 cases no specific site of the small intestine was identified, and in 2 cases the primary site was unknown. Of the 27 single tumors, 12 were single and 15 were multiple. The size of the naked eye tumor was 0.2-0.6 cm with an average of 2 cm. CT evaluation of mesenteric mass size, margins, density, radial cords, calcification, and intestinal wall thickness. Radial strips are light (thickness <10), moderate (thin
