中文摘要:

      目的 分析老年女性原发性输卵管癌的MRI表现,提高其诊断准确率.方法 回顾性分析2013 年1 月—2023年6 月在复旦大学附属华东医院经病理证实的15 例原发性输卵管癌MRI表现.测量病灶最大径,观察其信号强度、形态及增强后表现.测量其强化率、表观弥散系数(ADC)值,并与子宫肌层作统计学分析比较.结果 15 例输卵管癌病例共16 个病灶.条管影伴结节5 个,腊肠样病灶2 个,肿块样 9 个.6 个病灶见包膜强化.增强晚期病灶与子宫肌层强化率分别为(1.71±0.78)、(2.34±0.58),差异有统计学意义.病灶与子宫肌层ADC值分别为(0.788±0.133)×10-3mm2/s、(1.285±0.216)×10-3mm2/s,差异有统计学意义.输卵管积液5 例,宫腔积液1 例,未见正常卵巢.结论 老年女性原发性输卵管癌MRI具特征性表现.正常卵巢在老年女性输卵管癌患者中不易显示,可能会增加诊断难度.

英文摘要:

      Objective To analyze MRI manifestation of primary fallopian tube carcinoma(PFTC)in elderly women and improve its diagnostic accuracy.Methods MRI manifestation of 15 patients withPFTC confirmed by pathology in Hua-dong Hospital Affiliated to Fudan University from January 2013 to June 2023 was retrospectively analyzed.The maximum di-ameter of the lesion was measured,and the signal intensity,morphology and enhanced performance were observed.The en-hancement rate and apparent diffusion coefficient(ADC)value were measured and compared with those of myometrium.Results There were 16 lesions in 15 patientswithPFTC,including5 tubularia with nodules,2 salami lesions and 9 lumps.Cap-sular enhancement was observed in 6 lesions.The enhancement rates of late lesions and myometrium were(1.71±0.78)and(2.34±0.58),respectively,and the difference was statistically significant.The ADC values of the lesion and myometrium were(0.788±0.133)×10-3 mm2/s and(1.285±0.216)×10-3 mm2/s,respectively,with statistically significant differ-ences.Hydrosalpinx was found in 5 cases,hydrocele in 1 case,and no normal ovaries were found.Conclusion MRI of PFTC in elderly women has characteristic manifestation.Normal ovaries are not easily displayed in elderly female patients with PFTC,which may increase the difficulty of diagnosis.
