【摘要】 目的　探讨宫颈癌根治术后复发的CT检查和表现。材料与方法　搜集 37例宫颈癌根治术后复发病例 ,其中术后 7个月～ 1年 16例 ,1～ 2年 13例 ,2年以上 8例。所有病例均经CT平扫加增强以及B超检查。结果　 (1)CT表现 :中央型 2 2例 ,最小直径 1.5cm ,最大 8cm× 5cm ,平扫 2例阴性 ,2 0例阳性 ,增强后均为阳性。盆壁型 15例 ,其中 5cm× 4cm 8例 ,4cm× 3cm 5例 ,3cm以下 2例 ;左侧 10例 ,右侧 5例 ;平扫和增强均为阳性。 (2 )B超表现 :阴性 2例 ,阳性 35例。结论　CT平扫阳性率和B超相同 ,表现均无特征性 ,无法确诊。而增强CT不仅检出率最高 ,而且病灶表现具有边缘性强化 ,向内浸润 ,内缘凹凸不平且模糊的特征 ,故应视为常规检查更多还原

【Abstract】 Objective To study CT manifestations of postoperative recurrence of cervical carcinoma.Materials and Methods Of 37 recurrent cases of cervical carcinoma after radical operation, 16,13 and 8 patients relapsed 7～12 months, 1～2 years and over 2 years after operation, respectively. All the patients underwent CT scanning and sonography.Results (1) CT findings: In 22 cases of centric type, the size of recurrent lesions varied from 1.5cm in diameter to 5cm×8cm. On plain scan, 20 cases were positive with 2 cases negative, while on enhanced scan all cases were positive. All 15 cases of pelvic type were positive on both plain and enhanced scan. The recurrent lesions were 5cm×4cm (n=8), 4cm×3cm (n=5) or under 3cm (n=2) in size, locating on the left side (n=10) or right side (n=5). (2) Ultrasound findings: Positive findings were seen in 35 cases, negative in 2.Conclusion Plain CT scan and sonography provide the same diagnostic accuracy. Enhanced CT scan is the most sensitive method, thus, should be regarded as a routine exam. The characteristic findings of recurrent lesion on CT scans are peripheral enhancement with irregular or fuzzy inner margin.更多还原
