摘　　要：目的分析女性盆腔肿块CT误诊原因,从中吸取教训以减少误诊率。方法回顾性分析经手术病理证实的18例女性盆腔肿块CT误诊资料,所有患者均经层厚10mm,间距10mm平扫,6例行3～5mm薄层CT增强扫描,造影剂采用76%泛影葡胺和碘海醇(64.7g)100mL肘静脉团注。结果单纯囊性6例,单纯实性8例,囊实性2例,含脂肪及钙化2例,肿块大小约10mm×18mm×24mm～130mm×140mm×150mm,边缘光滑规则11例,不规则5例,部分边缘不清楚2例。结论不典型或巨大女性盆腔肿块容易导致CT定性或组织来源的误诊。Objective To analyze the misdiagnostic causes of female pelvic masses（FPMs） on CT images and to draw the lessons from this analysis,thus reducing the misdiagnostic rate.Methods Eighteen patients with clinically and pathologically proved FPMs underwent conventional CT plain scans with 10 mm slices and 10 mm intervals,of whom,6 patients underwent additional contrast-enhanced CT scans with 3-5 mm thin slices after intravenous bolus injection of 76% urografin or Iohexol（64.7 g） 100 ml.The CT data of all patients were analyzed retrospectively.Results Among 18 cases,simple cystic masses were found in 8,simple solid masses in 8,cystic-solid masses in 2,and intrafocal containing fat component and calcification in 2.The size of FPMs ranged from 10 mm ×18 mm×24 mm to 130 mm×140 mm×150 mm.The masses with smooth and regular margin were found in 11 cases,irregular margin in 5,and partially ill-defined margin in 2.Conclusion Atpical or huge FPMs easily led up to CT pitfalls in the qualitative diagnosis and the identify of histologic origin.
