64层螺旋CT对回盲部肿块的诊断价值

目的：探讨螺旋CT对回盲部肿块的诊断价值。方法收集54例经手术病理确诊有完整CT资料的回盲部肿块病例，进行良恶性对比分析。结果良性病变32例，以阑尾周围脓肿为多见；恶性病变22例，以盲肠、升结肠癌为多见。2组良恶性CT征象比较，囊性肿块、实性肿块、肠腔狭窄、不规则肠壁增厚、分层样肠壁增厚、肠旁脂肪浑浊、肠梗阻、远处转移、末端回肠受累差异均有统计学意义（P〈0.05）；而周围淋巴结肿大、肠套叠、腹水、邻近肌肉累及2组比较差异无统计学意义（P〉0.05）。结论螺旋CT对鉴别回盲部肿块的良恶性和确定病变范围有较高的应用价值。

The diagnosis value of ileocecal mass in 64-slice helical CT

Objective To evaluate the clinical value of helical CT in diagnosis of ileocecal mass. Methods 54 cases of ileocecal masses confirmed by surgical and pathological were comparatively analyed. Results most of 32 patients with benign masses were appendices surroundings abscess. most of 22 patients with malignant masses were cecal and colonic carcinoma. These CT signs,which included cystic masses, solid mass, narrow lumen, irregular thickening-bowel wall, stratified thickening bowel wall and fat turbidity around intestinal,intestinal obstruction,distant metastasis, terminal ileum involvement,were had statistically significant difference between benign and malignant lesions（P〈0.05）, while the surrounding lymph node enlargement,intussusception,ascites,adjacent muscle involvement,were had no statistical significance between the two groups （P〉0.05）.Conclusion Helical CT is a very useful diagnosis value in identify benign and malignant mass and determine the scope of the lesions.
