阑尾炎的临床诊断不可靠,误诊率可达50％。近年来,由于CT和US的进展,对疑为阑尾炎病人的影像评价有了提高。阑尾炎常是阑尾口阻塞的结果。偶尔,阑尾腔在远离开口处阻塞而发生所谓远侧阑尾炎。这在US和钡灌肠检查中常呈假阴性而被误诊,从而增加了阑尾穿孔的可能。作者回顾了180例病理证实为阑尾炎病人的CT扫描和病历资料,发现了14例远侧阑尾炎。所有病人均做了螺旋CT扫描,扫描前口服2.1％硫酸钡混悬液0～ Clinical diagnosis of appendicitis is not reliable, misdiagnosis rate of up to 50%. In recent years, the imaging evaluation of patients suspected of appendicitis has been improved due to the progress of CT and US. Appendicitis is often the result of obstruction of the appendix. Occasionally, the appendix lumen obstructs away from the opening and so-called distal appendicitis occurs. This is often false negative in US and barium enemas and is misdiagnosed, increasing the possibility of perforation of the appendix. The authors reviewed 180 cases of pathologically confirmed appendicitis in patients with CT scan and medical records, found in 14 cases of distal appendicitis. All patients were done a spiral CT scan before oral scanning 2.1% barium sulfate suspension 0 ~
