A 45-year-old female presents with abnormal uterine bleeding. An ultrasound reveals a hyperechoic, well-defined mass within the uterine cavity. What could be the potential causes?
A hyperechoic, well-defined mass within the uterine cavity on ultrasound in a woman presenting with abnormal uterine bleeding is suggestive of a uterine polyp or submucosal fibroid. Further characterization may be done with saline-infusion sonohysterography or hysteroscopy. Depending on the patient's symptoms, age, and reproductive plans, management options may range from observation to medical management or surgical removal.
