Arteriovenous malformation of the uterus is a rare but potentially life-thr
eatening lesion. We report a case of arteriovenous malformation of the uter
us in a 19-year-old nulliparous woman. The diagnosis was made with color Do
ppler sonography and was confirmed histologically. Color Doppler sonography
helps differentiate uterine arteriovenous malformation from other entities
that have a similar appearance on gray-scale sonograms. (C) 2000 John Wile
