Résumé
Objective To evaluate MRI features of tubal ovarian cysts,to improve the understanding of its imaging characters. Methods 1 5 patients with tubal ovarian cysts proved by pathology and surgery were analyzed retrospectively.Results Among the 1 5 cases with cysts,9 cases were solitary lesions,including the right side of the attachment area in 5 cases and the left side of the at-tachment area in 4 cases.6 cases were multiple lesions located on both sides.The diameters of these cysts were from 3.8 cm to 1 1.0 cm,and average diameter was 5.6 cm.All cases showed that the cysts were round,communicated with fallopian tube.All tubals showed different degrees of expansion.The signals of the cysts showed hypointense on T1 WI and hyperintense on T2 WI.The signals in two cases were complex.After contrast medium administration,the walls of the cysts could be enhanced with different de-grees.Conclusion MRI is useful in displaying the morphology,signal and the wall of the tubal ovarian cysts.
