Discussion of Arcuate uterus
- Arcuate uterus is characterized by a mild indentation of the endometrium at the uterine fundus
- Result of near complete resorption of the uterovaginal septum.
- Arcuate uterus can be distinguished from a bicornuate uterus on the basis of its complete fundal unification.
- Data regarding the reproductive outcomes of patients with an arcuate uterus are extremely limited and widely disparate.
 Imaging Findings for Arcuate uterus
- Opacification of the endometrial cavity demonstrates a single uterine canal with a broad saddle-shaped indentation of the uterine fundus.
- A normal external uterine contour is noted, with a broad smooth indentation on the fundal segment of the endometrium.
- No division of the uterine horns is noted.
- Normal external uterine contour is maintained.
- The myometrial fundal indentation is smooth and broad, and the signal intensity of this region is isointense to normal myometrium.
