A case of fallopian tube carcinoma: successful preoperative diagnosis with MR imaging.

We report a case of fallopian tube carcinoma, successfully diagnosed preoperatively. The patient was a 64-year-old woman. Transvaginal sonography and computed tomography showed a cystic and solid tumor on the left side of the uterus, suggesting ovarian cancer. The tumor was, however, suspected to be a fallopian tube carcinoma on MR imaging. MR images showed a solid mass surrounded by a tube-shaped cystic part. At surgery, a solid and cystic tumor was found in the left fallopian tube. MR imaging may be useful to assist in the diagnosis of fallopian tube carcinoma.
