Abstract:
Objective To explore the MRI features of pelvic endometriosis outside the ovary.Methods 13 patients with pelvic endometriosis outside the ovary were imaged.Their clinical and imaging data were reviewed retrospectively.All cases were con-firmed by pathology.An enhanced MR using T1 WI sequence both in sagittal and transverse position was performed after T2 WI fat-suppression sequence and T1 WI sequence.Our MRI study was focused on the distribution of lesions locating in the deep pelvic cavity and abdominal wall,and the features of MRI signals .Results 13 lesions were found,in which 4 lesions located in the rectouterine pouch of Douglas,2 cases the bladder wall,2 cases the unilateral cystic inlet of ureter,1 case the anal canal wall,and 4 cases the ab-dominal wall.10(10/13)lesions were shown as solid nodules while 3(3/13)lesions as cyst-solid ones.All lesions showed moderate-ly heterogeneous enhancement.Conclusion Pelvic endometriosis outside the ovary mainly shows solid or cyst-solid lesions that lo-cates in the urinary,uterus,rectal wall and spaces around them.MR images show a higher value for the detection of the lesions out-side the ovary.
