Preoperative diagnosis of primary fallopian tube carcinoma by magnetic resonance imaging: a case report.

Because of the rarity and insidious onset of primary adenocarcinoma of the fallopian tube, early diagnosis is very difficult. Primary fallopian tube carcinoma is also rarely diagnosed preoperatively. This report reviews the value of magnetic resonance imaging (MRI) in aiding the detection of early-stage primary fallopian tube carcinoma in a 48-year-old female. The diagnosis was based on clinical suspicion, elevated CA-125 and MRI. MRI demonstrated the tumor as an area of solid masses with marked enhancement after gadolinium-diethylenetetraaminepentaacetic acid (Gd-DTPA) administration. Primary fallopian tube carcinoma was confirmed by pathologic examination. We hope that, with improvements in imaging, early diagnosis of such a malignant disease could become routinely possible in the future.
