急性阑尾炎的CT诊断

目的探讨急性阑尾炎的CT表现及其诊断价值。方法回顾性分析经手术、病理证实的30例急性阑尾炎的CT资料并与病理对照。结果30例急性阑尾炎中，单纯性阑尾炎20例，急性化脓性阑尾炎6例，阑尾脓肿4例。主要CT表现：20例单纯性阑尾炎CT表现为阑尾增粗、壁增厚；6例急性化脓性阑尾炎CT表现为阑尾增粗、壁增厚，阑尾周围炎性改变；4例阑尾脓肿CT表现为回盲区软组织包块，其内密度不均，右髂窝及盆腔积液，其中2例并发小肠梗阻；30例中7例可见阑尾粪石。结论CT是显示急性阑尾炎较好的检查方法，能够为临床诊断提供帮助。能够为临床诊断和治疗提供重要的依据。

CT diagnosis of acute appendicitis

Objective To investigate the value of CT in diagnosis of acuteppendicitis. Methods Acute appendicitis was confirmed by pathology in 30 cases after the operation. CT features of 30 acute appendicitis were analyzed and compared with the surgery and pathological results retrospectively. Results Among of 30 acute appendicitis,20 cases were simple appendicitis,6 cases were acute suppurative appendicitis and 4 cases were appendiceal abscess. 20 cases simple appendicitis showed the appendix enlarged in diameter,with wall thickening in CT imaging. 6 cases acute suppurative appendicitis showed the appendix enlarged in diameter,with wall thickening and periappendiceal inflammation in CT imaging. 4 cases appendiceal abscess showed inflammatory tumors with asymmetrical attenuation in ileocecal region and complicating fluid collection in right iliac fossa and cavity of pelvis in CT imaging. In 4 cases appendiceal abscess,2 cases complicated small intestine obstruction. 7 cases appendiceal fecalith were found in 30 acute appendicitis. Conclusion CT scanning can illustrate feature of acute appendicitis and make correct diagnosis,and can provide important information for clinician.
