Primary fallopian tube carcinoma (PFTC) is seldom diagnosed preoperatively and is often mistaken for epithelial ovarian carcinoma (EOC). This report details a case of primary high-grade serous carcinoma (HGSC) of the fallopian tube, highlighting radiological and clinical indicators to aid in accurate diagnosis and avoid misdiagnosis. A 46-year-old premenopausal woman presented with symptoms and a transvaginal ultrasound (TVUS) indicating a malignant ovarian tumor. Further imaging with CT and MRI revealed a solid-cystic mass suggestive of a fallopian tube tumor rather than an ovarian origin. Oncological surgery confirmed the presence of a high-grade serous carcinoma in the fallopian tube. This case underscores the diagnostic challenges of PFTC and the superior sensitivity and specificity of MRI over CT and US in distinguishing adnexal lesions. Key MRI features such as the sausage-shaped mass and associated hematosalpinx were crucial in differentiating PFTC from EOC. The report emphasizes the importance of considering PFTC in differential diagnoses of adnexal masses to ensure accurate preoperative identification.
原发性输卵管癌（PFTC）术前很少被诊断出来，常被误诊为上皮性卵巢癌（EOC）。本报告详细介绍了一例输卵管原发性高级别浆液性癌（HGSC）病例，强调了有助于准确诊断并避免误诊的影像学和临床指标。一名46岁的绝经前女性出现症状，经阴道超声（TVUS）显示为恶性卵巢肿瘤。进一步的CT和MRI成像显示为实性囊性肿块，提示为输卵管肿瘤而非卵巢来源。肿瘤外科手术证实输卵管存在高级别浆液性癌。该病例强调了PFTC的诊断挑战，以及MRI在鉴别附件病变方面优于CT和超声的敏感性和特异性。关键的MRI特征，如腊肠样肿块和相关的输卵管积血，对于区分PFTC和EOC至关重要。该报告强调了在附件肿块的鉴别诊断中考虑PFTC的重要性，以确保术前准确识别。
