The Use of Point-of-Care Ultrasound for the Diagnosis of Mullerian Abnormality in the Pediatric Emergency Department

We present a case of an 18-year-old female patient with a history of primary amenorrhea presenting to a pediatric emergency department with complaint of new-onset vaginal bleeding. Upon the patient's presentation, she received a point-of-care ultrasound (POCUS), which promptly identified the lack of a uterus and led to the diagnosis of a mullerian duct anomaly. This is the first published report of mullerian agenesis identified in the pediatric emergency department using a transabdominal approach to pelvic POCUS. We recommend POCUS as a quick, noninvasive diagnostic approach for pediatric patients presenting with undifferentiated vaginal bleeding to guide further management.
