Abstract:
Objective To investigate the imaging findings of oblique vaginal septum syndrome and its diagnostic value.Methods Clinical and radiographic data of 13 patients with oblique vaginal septum syndrome were analyzed retrospectively and relevant literatures were reviewed.All 13 patients underwent ultrasonography examination preoperatively,and 8 of them underwent MRI examination,and 3 patients underwent CT examination as well.The position of the oblique septum,the size of the cavity in the rear of oblique septum, the positional relationship between the cavity in the rear of oblique septum and the cervix,and the concomitant changes of the uterine appendages and urinary system were analyzed.Results The ultrasonography and MRI examinations all manifested as uterus didelphys,cervix duplex,double vagina and obstructed hemivagina,and oblique septum originated from the middle of cervix duplex and attached to one side of the vaginal wall,shielding the ipsilateral cervix;oblique vaginal septum was on the right side in 4 cases and on the left side in 9 cases;the average volume of the cavity in the rear of oblique septum in 6 cases of type Ⅰ was 255 mL,and the average volume in 6 cases of type Ⅱ was 74 mL,and the volume in 1 case of type Ⅲ was 56 mL;2 cases were combined with ipsilateral hematosalpinx and 1 case was combined with a chocolate cyst of ipsilateral ovary;12 cases were accompanied with ipsilateral renal agenesis and 1 case was accompanied with ipsilateral renal hypoplasia.CT examinations of 3 cases all presented as uterus didelphys,a cystic hypodensity lesion under unilateral cervix and ipsilateral renal agenesis.Conclusion Imaging findings of oblique vaginal septum syndrome are quite characteristic. Ultrasonography,CT and MRI examinations have certain value for accurate diagnosis of the disease.
