Sonographic Features of Uterine Arteriovenous Malformations: Two and Three dimensional Findings

Uterine arteriovenous malformations (AVMs) are uncommon but occasionally serious and even life-threatening vascular lesions within the myometrium. They are detectable with traditional two-dimensional (2D) ultrasonography and color Doppler mapping. The diagnosis is made by visualizing a hypervascular region or mass within the myometrium. We report a case of uterine AVMs that was diagnosed with 2D and three-dimensional (3D) ultrasonography and confirmed by post-hysterectomy histology. When women have abnormal uterine bleeding with a heterogeneous myometrial mass, even in pregnancy, uterine AVMs should be considered.
