探讨原发性输卵管癌（PFTC）的超声特征，分析误诊原因，以提高对该病的超声诊断水平。

对2008年8月至2016年11月解放军总医院收治并经手术病理证实的41例原发性输卵管癌患者的临床、病理资料及超声声像图分型表现进行分析。

41例原发性输卵管癌声像图表现：（1）Ⅰ型6例，显示附件区迂曲管状囊性结构，囊壁见单发或多发乳头样突起，彩色多普勒示乳头上见较丰富的血流信号。（2）Ⅱ型2例，显示附件区囊实性肿块，呈腊肠形改变，边界清楚，在实性部分周边或一侧沿输卵管走行方向见囊性区，彩色多普勒示实性部分见较丰富或丰富的血流信号。（3）Ⅲ型13例，显示附件区低回声肿块，呈腊肠形改变，边界清楚，彩色多普勒示其内见较丰富或丰富的血流信号。（4）Ⅳ型14例，附件区单发或多发实性为主低回声肿块，形态欠规则，彩色多普勒示实性部分见较丰富或丰富的血流信号，一侧或双侧未显示正常卵巢结构，伴膀胱子宫陷窝腹膜增厚、子宫直肠陷窝腹膜增厚、大网膜增厚、远处其他脏器转移等1项或多项恶性征象。（5）Ⅴ型6例，仅表现输卵管积液或超声显示附件区无异常改变。术前超声提示原发性输卵管癌19例（46.3%，19/41）、误诊及漏诊22例（53.7%，22/41）。

原发性输卵管癌超声声像图有一定特征性，但病变较小时超声易漏误诊。超声检查可显示输卵管病变位置、大小、内部回声、血流及其他脏器转移情况，可作为原发性输卵管癌术前诊断及术后随访的首选影像学方法。

To analyze ultrasonographic imaging feature of primary fallopian tube carcinoma (PFTC) and the reasons for misdiagnosis.

Clinical data and ultrasonographic imaging feature of 41 patients with pathologically confirmed PFTC were retrospectively analyzed from August 2008 to November 2016 in General Hospital of Chinese People′s Liberation Army.

Ultrasonographic characteristics of 41 PFTC cases: (1) TypeⅠ(6 cases), the cystic adnexal mass with single or multiple papillary projections and circuity tubular structures, color Doppler flow imaging showed abundant blood flow signal inside the nipples. (2) TypeⅡ(2 cases), the sausage shaped complex adnexal mass showed clear boundary, the cystic area that lined along the fallopian tube was around or at the side of the solid part, color Doppler flow imaging showed rich or abundant blood flow signal inside the solid part. (3) Type Ⅲ (13 cases), the sausage shaped hypoechoic adnexal mass showed clear boundary, color Doppler flow imaging showed rich or abundant blood flow signal inside the mass. (4) TypeⅣ (14 cases), the single or multiple adnexal masses showed irregular surface, with predominant solid components, color Doppler showed rich or abundant blood flow signal inside the tumor; the normal ovarian structure was not detected in unilateral or bilateral adnexa area; and one or more signs of metastasis were found, such as the peritoneal thickening of vesicouterine pouch, uterine rectum pouch and omental, metastasis to other distant organs, and so on. (5) Type Ⅳ(6 cases), only hydrosalpinx or no abnormal ultrasonographic changes in the adnexal area. Nineteen (46.3%, 19/41) cases were correctly diagnosed by preoperative ultrasonography, while 22 (53.7%, 22/41) cases were missed or misdiagnosed.

Ultrasonography imaging of PFTC has certain characteristics, but it tends to be missed or misdiagnosis when the lesion is small. Ultrasound can show the location, size, internal echo, blood flow and distant metastasis of lesion, which can be taken as the first choice of imaging methods for preoperative diagnosis and postoperative follow-up of PFTC.
