Figure 1 Pelvic ultrasonography demonstrating age-appropriate prepubertal uterusPelvic ultrasonography in the sagittal plane shows a prepubertal uterus (blue arrows) with fundus-to-cervix ratio of approximately 2: 1. The endometrial echo is thin, and no uterine or adnexal cysts or masses are identified. These findings are consistent with prepubertal internal genitalia and indicate the absence of sonographic signs of pubertal activation. Ultrasound examination was performed using grayscale imaging with a transabdominal approach.
