| ［摘要］ 目的 分析急性阑尾炎的临床表现特点及CT影像学特征。方法 回顾性分析该院2015-11～2017-10经外科手术切除和病理证实的62例急性阑尾炎患者的临床及影像学资料。结果 62例急性阑尾炎中，阑尾位置：常见位置56例，低位5例，高位1例。CT征象：4例阑尾CT无法辨出，58例阑尾的直径为（1.04±0.31）cm，其中>6 mm的53例，<6 mm的5例。阑尾积液41例，阑尾壁增厚（>2 mm）48例，阑尾结石17例，阑尾周围渗出54例，蜂窝织炎10例，阑尾周围脓肿5例，阑尾周围积气6例，腹膜炎29例，腹水9例，回盲部肠壁增厚39例，淋巴结增大10例。1例急性阑尾炎增强CT表现阑尾壁肿胀增厚、强化明显。手术及病理结果：单纯性阑尾炎8例，化脓性阑尾炎37例，坏疽性阑尾炎17例。并发症中，穿孔9例，脓肿形成5例，弥漫性腹膜炎11例，局限性腹膜炎18例。结论 急性阑尾炎的CT征象中，阑尾增粗、阑尾积液、阑尾壁增厚、阑尾周围渗出有较高的特异性。CT对急性阑尾炎诊断率高，在临床上有较高的应用价值。 |

| ［Abstract］ Objective To analyze the clinical features and CT imaging data of acute appendicitis. Methods The clinical and CT imaging data of 62 cases with acute appendicitis proved by surgical resection and pathology in our hospital from November 2015 to October 2017 were retrospectively analyzed. Results In the 62 cases with acute appendicitis, the appendix positions: 56 cases of common positions, 5 cases of low positions, 1 case of high position. CT findings: 4 cases were illegible by appendicular CT. The diameter of the appendixes was (1.04±0.31)cm in 58 cases among whom the diameters were larger than 6 mm in 53 cases and smaller than 6 mm in 5 cases. Appendiceal effusion occurred in 41 cases, appendix wall thickening(>2 mm) in 48 cases, appendicium calculi in 17 cases, appendicium exudation in 54 cases, cellulites in 10 cases, abscess around appendicium in 5 cases, cumulation around appendicitis in 6 cases, peritonitis in 29 cases, ascites in 9 cases, thickening of ileum in 39 cases and enlarged lymph nodes in 10 cases. In 1 case with acute appendicitis, the swelling of appendix was thickened and strengthened obviously. The surgical and pathological results: simple appendicitis was found in 8 cases, pyogenic appendicitis in 37 cases, and gangrenous appendicitis in 17 cases.The complications: perforation occurred in 9 cases, abscess formation in 5 cases, diffuse peritonitis in 11 cases and localized peritonitis in 18 cases. Conclusion Some specific CT signs are found in acute appendicitis: enlargement of the appendix, effusion of the appendix, thickening of the wall of the appendix and the exudation around the appendix. CT has a high diagnostic value for acute appendicitis. |
