Purpose of investigation: The aim of this report is to describe a case of uterine arteriovenous malformation that occurred in a 54-year-old postmenopausal woman referring recurrent postmenopausal bleeding, after two years of tamoxifen therapy.
Methods: Medical therapy with GnRh agonists was unsuccessful. Ultrasound and Doppler flow ultrasound scanning were normal and the following hysteroscopy was normal as well.
Results: Hysterosonography performed on the patient made us suspect the presence of an intracavitary vascular lesion which was confirmed histologically after hysterectomy.
Conclusion: In our case hysterosonography allowed us--by creating optimal contrast between the uterine wall and the uterine cavity--to suspect and identify the lesion and to recognize the typical ultrasound findings of this pathology not visualized with standard transvaginal ultrasound.
