[Magnetic resonance in the evaluation of Mullerian duct anomalies].
Müllerian duct alterations in development or fusion in the embryo cause congenital uterine anomalies which may be responsible for decreased fertility or problems in carrying out a normal pregnancy. In this study, the MR findings in uterine agenesis (1 case), unicornuate (2 cases), didelphys (3 cases), bicornuate (3 cases), arcuate (6 cases) and septate uterus (8 cases) are described, together with the optimal section planes for their demonstration. The examinations were performed with an 0.5-T superconductive magnet, the spin-echo technique and mostly T2-weighted sequences. The anomalies were grouped according to Buttram and Gibbons classification, which is the most used in clinics. In particular, the bicornuate uterus was distinguished from the septate uterus, the latter associated with the highest spontaneous abortion rates, on the basis of external fundal outline appearance. In such anomalies, the muscular or fibrotic nature of any intracavitary septum was assessed based on septal thickness more than on signal intensity at this level. MR diagnostic accuracy in 23 patients with Müllerian anomalies, compared with surgical, hysteroscopic, laparotomic and laparoscopic findings, was 100%. Nevertheless, if Müllerian duct anomalies responsible for gynecologic-obstetric problems are known or suspected, MRI should always be used, on the basis of a close gynecologist-radiologist collaboration, for classification agreement and the evaluation of any intracavitary septum morpho-biometric appearance and possibly nature, to discuss treatment options.
