The junction zone (JZ), or a small distinct hormone-dependent region at the endometrial-myometrial interface, may be assessed by three-dimensional transvaginal ultrasound (3D TVUS) and MRI. Features of adenomyosis are disruption, thickening, enlargement or invasion of the junctional zone. [ 21 ]
Symptoms depend on whether the cervical canal is partially or completely obstructed and on the patient's menopausal status. Pre-menopausal patients may have a build up of blood inside the uterus which may cause infection, sporadic bleeding, or pelvic pain.
When the endometrial mucous membrane is found outside of the uterus in places such as the ovaries, it causes chronic pelvic pain with intercourse and menstrual cycles. Endometriomas can produce a toxic environment by producing estrogen, cytokines, interleukins, and other inflammatory substances, that could damage healthy endometriomal tissue.
The myometrium is located between the endometrium (the inner layer of the uterine wall) and the serosa or perimetrium (the outer uterine layer).. The inner one-third of the myometrium (termed the junctional or sub-endometrial layer) appears to be derived from the Müllerian duct, while the outer, more predominant layer of the myometrium appears to originate from non-Müllerian tissue and is ...
Bandl's ring (also known as pathological retraction ring) is the abnormal junction between the two segments of the uterus; it is a late sign associated with obstructed labor. [1] Prior to the onset of labor, the junction between the lower and upper uterine segments is a slightly thickened ring.
Asherman's syndrome (AS) is an acquired uterine condition that occurs when scar tissue forms inside the uterus and/or the cervix. [1] It is characterized by variable scarring inside the uterine cavity, where in many cases the front and back walls of the uterus stick to one another.
Uterine adenomyoma, the localized form of uterine adenomyosis, is a tumor composed of endometrial gland tissue and smooth muscle in the myometrium. [2] Adenomyomas containing endometrial glands are also found outside of the uterus, most commonly on the uterine adnexa but can also develop at distant sites outside of the pelvis . [ 3 ]
