Accessory Cavitated Uterine Malformation (ACUM) can be misdiagnosed as other uterine pathologies, such as Müllerian anomalies, adenomyosis, or fibroids. In the present case series, we report on data of eleven cases of ACUM. The mean age at diagnosis was 24.5 years. Nine patients presented with abdominal pain, one patient complained of infertility, and one patient was asymptomatic. One patient had a bilateral lesion. The average maximum lesion size was 26 mm. Ultrasound characteristics of the twelve lesions showed cystic lesions located in the uterine cornual region, containing ground glass or anechoic content. Imaging, particularly gynecological ultrasound, plays a fundamental role in identifying this condition.
