为确定肠系膜淋巴结炎临床酷似阑尾炎的比率及其CT表现,作者对651例入院诊断为阑尾炎病人的资料进行回顾性分析,结果50例(7.7％)最后诊断为肠系膜淋巴结炎,占252例最后诊断为非阑尾炎病人的19.8％。作者还对100例临床疑诊为阑尾炎病人行前瞻性右下腹部螺旋CT扫描。扫描前半小时病人口服2.1％的硫酸钡混悬液,扫描前经直肠导管结肠内注入3％的泛影葡胺300～1000ml。
To determine the clinical resemblance of appendicitis to meningococcal lymphadenitis and its CT findings, the authors retrospectively analyzed data from 651 admitted patients diagnosed as appendicitis resulting in a final diagnosis of mesenteric lymphadenitis in 50 (7.7%) of the 252 patients 19.8% of non-appendicitis patients. The authors also performed a prospective, right lower quadrant spiral CT scan on 100 patients with clinically suspected appendicitis. Half an hour before scanning the patient was orally administrated with 2.1% barium sulphate suspension and 300 ~ 1000ml of 3% diatrizoate was injected into the colon of rectum catheter before scanning.
