The existence of a longitudinal vaginal septum with double cervix communicating bilaterally with a nonseptate uterine body and normal adnexa is an unusual müllerian anomaly.
A 43-year-old woman presented with menorrhagia and duplication of the cervix and vagina. Afibromatous uterus was suggested by clinical examination and confirmed by ultrasonography. The patient underwent total abdominal hysterectomy with bilateral salpingooophorectomy. The surgical specimen revealed a fibromatous uterus with double cervix communicating bilaterally with a nonseptate uterine body; both adnexa were normal.
This rare müllerian anomaly is inconsistent with the classical embryologic theory of caudal to cranial müllerian development but supports the alternative embryologic hypothesis suggested by Müller et al, according to which fusion and absorption begin at the isthmus and proceed simultaneously in both the cranial and caudal directions.
存在纵向阴道纵隔且双宫颈双侧与非纵隔子宫体及正常附件相通是一种不寻常的苗勒管异常。
一名43岁女性因月经过多及宫颈和阴道重复畸形就诊。临床检查提示为纤维瘤性子宫,超声检查予以证实。患者接受了全腹子宫切除术及双侧输卵管卵巢切除术。手术标本显示为纤维瘤性子宫,双宫颈双侧与非纵隔子宫体相通;双侧附件均正常。
这种罕见的苗勒管异常与经典的从尾端向头端的苗勒管发育胚胎学理论不一致,但支持Müller等人提出的另一种胚胎学假说,即融合和吸收从峡部开始,并在头端和尾端同时进行。
