A case of isolated torsion of the fallopian tube: Added value of magnetic resonance imaging

Abstract

Fallopian tube torsion is a rare occurrence, which generally presents in the reproductive age group. The clinical and imaging features are usually non-specific and misdiagnoses are often made. We report an imaging case of an 18-year-old girl with isolated fallopian tube torsion, which could be diagnosed preoperatively thanks to control MR imaging. The initial MRI demonstrated the enlarged and tortuous fallopian tube with normal ovaries and uterus, and an equivocal mass near the uterus. The control MRI, five days later, showed the appearance of blood in the fallopian tube and in the equivocal mass, corresponding to the twisted pedicle.
