Preoperative sonographic diagnosis of primary fallopian tube carcinoma

Primary tumors of the fallopian tube are rare entities, constituting about 0.18% to 1.6%1 of all gynecologic malignancies. Although the classic triad of abnormal vaginal bleeding, leukorrhea, and abdominal pain is said to be pathognomonic, the correct preoperative diagnosis is made in only 0.3% of case.2 Bilateral disease is uncommon and represents less than one fourth of cases.3 This report describes a case of fallopian tube carcinoma in a relatively young woman, diagnosed preoperatively on the basis of characteristic sonographic features.
