Objective To explore the MRI imaging features of tumor torsion in female attachment area, and to improve the diagnostic coincidence rate of MRI. Methods Retrospectively analyzed the MRI and ultrasonographic data of 35 cases of tumor pedicle torsion confirmed by surgical pathology in our hospital from November 2012 to January 2017, and discussed the MRI features of the tumor. Results The group of 35 patients, ovarian cyst torsion in 15 cases, ovarian cystadenoma torsion in 5 cases, teratoma torsion in 7 cases, tubal cystic torsion in 4 cases, 3 cases of simple ovarian pedicle torsion, 1 case of torsion of subserosal fibroids, 1 case of teratoma torsion with gestation (28 weeks), 1 case of simple ovarian pedicle torsion with tubal hematoma (15 weeks of gestation), teratoma torsion with thyroid, luteal hematoma in 1 case. MRI characteristic manifestation: attachment area mixed signal mass, connected with the uterus side (100%, 35/35); Mass pedicle display (91.43%, 32/35), Whirlpool sign (65.71%, 23/35), Triangular sign (65.71%, 23/35), cyst wall near the pedicle crescent-shaped, curved thickening (68.57%, 24/35), combined pelvic fluid (82.86%, 29/35). The coincidence rate of nuclear magnetic diagnosis (85.71%, 30/35) was higher than that of ultrasound ultrasound (71.43%, 25/35). Conclusion The MRI features of tumor pedicle torsion in female attachment area have certain characteristics, and MRI has some diagnostic value.
