Leiomyomas of the uterus generally have a characteristic ultrasound appeara
nce. We present a case of leiomyoma of the broad ligament of the uterus. A
46-year-old woman who had previously undergone a hysterectomy had a pelvic
mass with a whorled appearance and acoustic shadowing suggestive of a leiom
yoma on sonography. Based on the sonographic appearance, a preoperative dia
gnosis of a leiomyoma was made despite the unusual location. Histologic exa
mination of the excised mass revealed leiomyoma originating from the broad
ligament. (C) 1999 John Wiley & Sons, Inc.
