This study aimed to investigate the imaging features of primary fallopian tube carcinoma (PFTC).
Imaging findings of 12 PFTC patients were retrospectively studied. Multi-slice computed tomography (CT, MSCT) was performed to investigate tumor location, size, density, appearance (cystic/solid), enhancement pattern, and metastasis.
Twelve women aged 34-67 (mean=54.3) years were presented with pelvic pain (n=6), vaginal discharge (n=5), and incidental pelvic masses (n=3). The tumor diameters of PFTC varied from 3.3 to 6.8 cm (mean=4.7 cm). Ten cases were unilateral, and two were bilateral. The lesions were adnexal tubular-shaped cystic masses with mucosal papillary nodes in six cases, irregular cystic and solid masses in four cases, and sausage-shaped solid masses in two cases. The plain CT values ranged from 15 to 35 HU (mean, 28 HU). On enhanced CT, the enhancement of the solid composition was lower than that of the myometrium in all phases. CT values in arterial and venous phases were 55-62 and 60-63 HU, respectively, with average values of 58.6 and 61 HU. The metastasis sites included the ovary (n=2), omentum (n=3), retroperitoneal lymph nodes (n=5), pelvic lymph nodes (n=5), and inguinal lymph nodes (n=2). Seven cases exhibited pelvic fluid, and seven exhibited round ligament thickening on the lesioned side.
In patients presenting with vaginal discharge or genital bleeding and sausage-shaped or tubal-shaped cystic, solid, or solid-cystic complexes in the adnexal portion associated with hydrosalpinx and peritumoral ascites, PFTC should be considered in the diagnosis, especially in tumors associated with round ligament thickening.
本研究旨在探讨原发性输卵管癌（PFTC）的影像学特征。
回顾性分析12例PFTC患者的影像学表现。采用多层螺旋计算机断层扫描（CT，MSCT）观察肿瘤的位置、大小、密度、形态（囊性/实性）、强化方式及转移情况。
12例患者年龄34 - 67岁（平均54.3岁），表现为盆腔疼痛（6例）、阴道分泌物增多（5例）及偶然发现盆腔肿块（3例）。PFTC肿瘤直径3.3 - 6.8 cm（平均4.7 cm）。10例为单侧，2例为双侧。病变表现为附件区管状囊性肿块伴黏膜乳头状结节6例，不规则囊实性肿块4例，腊肠样实性肿块2例。CT平扫值15 - 35 HU（平均28 HU）。增强CT扫描，各期实性成分强化均低于子宫肌层。动脉期和静脉期CT值分别为55 - 62 HU和60 - 63 HU，平均值分别为58.6 HU和61 HU。转移部位包括卵巢（2例）、大网膜（3例）、腹膜后淋巴结（5例）、盆腔淋巴结（5例）及腹股沟淋巴结（2例）。7例有盆腔积液，7例患侧圆韧带增厚。
对于出现阴道分泌物增多或生殖器出血，附件区腊肠样或管状囊性、实性或囊实性肿物伴输卵管积水及肿瘤周围腹水的患者，诊断时应考虑PFTC，尤其是伴有患侧圆韧带增厚的肿瘤。
