Adenomyosis of the uterus

The uterus has two parts, functionally speaking, the endometrium (or the inner lining of the uterus) and the myometrium (the thick muscular wall of the uterus). During menses, a part of the endometrial lining is shed along with the menstrual blood. In women with adenomyosis there is ectopic (abnormally located) endometrial tissue located deep inside the wall of the uterus (myometrium). This ectopic (adenomyotic tissue) also undergoes menstrual bleeding resulting in severe pain within the wall of the uterus (dysmenorrhea). Many experts believe that adenomyosis is one of the leading causes of pain during menses in women. These ultrasound and color Doppler videos show marked congestion (increased vascularity) within the hyperechoic lesion in the posterior wall of the body of the uterus. This lesion represents the site of adenomyosis.

This is a transvaginal gray ultrasound video (above) showing the inhomogenous hyperechoic area in the posterior wall of the myometrium in the body of the uterus (arrows).
The color Doppler video below shows hypervascularity in the lesion:
This ultrasound and color Doppler video shows a transverse section of the uterus, panning the probe from superior to the inferior part of the uterus.(see below).
The adenomyotic lesion is seen to compress upon the endometrial stripe also, adding to the woes of the patient.
Lastly this Power Doppler video further shows the increased vascularity/ hyperemia of the entire uterus, besides that of the adenomyotic lesion.
