The term Cesareancaesarean scar niche (defect) refers to the presence of a hypoechoic area within the myometrium in the isthmus (lower uterine segment) with discontinuation of myometrium at the site of a previous Cesareancaesarean section scar. A niche has been described as the indentation of myometrium of around 1-2 mm 1,4and due due to tethering of the endometrium.
They are encountered in various shapes such as:
- semicircular: considered commonest 4
- triangular: next commonest 4
- droplet‐shaped
- inclusion cysts
Due to tethering of the endometrium, blood accumulates in a niche and may serve as a source of dysfunctional uterine bleeding, accounting for spotting 2-12 days after the routine menstrual cycle 5.
