The Anatomy Of An Arcuate Uterus

Description

Arcing gently along the superior uterine fundus, this animation focuses on the arcuate uterus, where a shallow midline indentation subtly projects into the endometrial cavity. The sequence traces the external fundal contour from an anterior to posterior sweep, then transitions to a cutaway view that clarifies how the myometrium and endometrium shape a smooth, broad-based concavity rather than a deep septation. Coronal and sagittal relationships are emphasized so the viewer can orient the fundus superiorly, the cervix inferiorly, and the uterine cavity centrally along the midline. Classification of uterine cavity variants hinges on small differences in fundal morphology, and that matters in infertility and recurrent pregnancy loss workups where imaging reports drive counseling. By animating the contour change across planes, the piece helps distinguish an arcuate uterus from a septate uterus, where a fibrous or muscular septum extends inferiorly into the cavity and can be targeted by hysteroscopic septum resection. Small distinction. Big management implications. The motion also mirrors how the finding is appreciated in practice, alternating between 2D ultrasound slices, sonohysterography distension of the cavity, and the coronal reformats of 3D transvaginal ultrasound or MRI that clinicians rely on to measure indentation depth and fundal serosal outline. Use this animation in reproductive endocrinology lectures, OB-GYN resident teaching on Mullerian anomalies, or as an explanatory visual for radiology reports accompanying pelvic ultrasound, 3D ultrasound, or MRI. It also supports patient-facing counseling materials where you need a calm, accurate depiction of a minor fundal curve rather than a pathologic intracavitary septum.
