年轻女性盆腔肿块的CT表现分析

CT Manifestations of Pelvic Mass in Young Female

目的:分析和总结40周岁以下女性盆腔肿块的CT表现,以提高诊断水平。方法:回顾性分析经手术、病理和临床随访证实的40周岁以下女性盆腔肿块135例共176个病灶,年龄16～40岁,平均32.5岁,87例增强扫描。结果:112例单病灶,15例双病灶,8例含多病灶,共176个肿瘤或占位病变,可归纳为3种类型:(1)大部分病例来源明确,表现典型,属于良性,占65.9%(89/135);(2)部分病例表现不典型,定位定性困难,良恶性兼有,仍以良性比例大,占25.2%(34/135);(3)个别病例表现无特殊,结合病史良恶性难定,最终依赖病理诊断,占8.9%(12/135)。结论:年轻女性盆腔肿块大部分CT表现典型,属于良性,易诊断;少数病例CT表现缺乏特征性,似恶性,临床病史也不明确,即使是良性也难诊断而最终完全依赖病理。

Objective：To promote the level of diagnosis of pelvic mass, analysis and summarize its CT manifestations in female under forty years old. Methods：The CT appearances of 135 cases with pelvic mass proved by operations,pathology or clinic were retrospectively analyzed.Results：There were totally 176 lesions in 135 cases, while 112 cases with single lesion, 15 cases with double lesions, other 8 cases with triple in each eases at least.They were categorized into three types according to their origin：（1）Most cases （65.9%, 89/135） with definite origin and typical CT appearances were benign. （2）Some cases （25.2%,34/135） without typical CT appearances were either benign or malignant, but benign lesions were predominant. （3）Other cases （8.9% ,12/135） without special CT appearances were difficult to diagnosis, ultimately proved by pathology.Conclusion：Most pelvic masses with typical CT appearances in young female were benign and easy to diagnosis; while few cases without special CT appearances or determined history were formidable to diagnosis, completely depending on pathology.
