What is transient myometrial contraction and what causes it?
Dr Yuranga Weerakkody ◉ and Dr Dalia Ibrahim et al. Transient myometrial contraction is a physiological phenomenon which may mimic focal adenomyosis. It appears as focal low signal intensity bulge/region of the myometrium which may disappear on subsequent images or at cine MR imaging.
Which ultrasound findings are characteristic of focal myometrial contraction?
Focal myometrial contraction as defined by transvaginal ultrasound findings: Thickening of the myometrial portion of the uterine wall visualized as two distinctly different areas of echogenicity An unusually long-appearing cervix (possibly more than 50 mm) with an S-shaped endocervical canal and apparent internal os located appreciably cephalad
Why does the myometrium stretch during pregnancy?
The myometrium stretches (the smooth muscle cells expand in both size and number) during pregnancy to allow for the uterus to become several times its non-gravid size, and contracts in a coordinated fashion, via a positive feedback effect on the “ Ferguson reflex „, during the process of labor.
What is the function of the myometrium?
The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes), but also of supporting stromal and vascular tissue. Its main function is to induce uterine contractions.
