Imaging findings of a torsed pedunculated uterine leiomyoma: A case report

Torsion of a pedunculated uterine leiomyoma is an incredibly rare occurrence, considered a surgical emergency due to the risk of ischemic gangrene and resulting reactive peritonitis. Imaging modalities have traditionally played a limited role in evaluation of leiomyoma torsion due to modest sensitivity and specificity. We present the case of a 58-year old female with a known pedunculated fibroid who presented with acute abdominal pain. Computed tomography and ultrasound findings suggested a preoperative diagnosis of leiomyoma torsion, confirmed intraoperatively. While direct visualization at surgery remain the primary means of diagnosis of pedunculated fibroid torsion, familiarity of potential imaging findings in conjunction with the clinical presentation may enable the interpreting radiologist to consider this entity in the differential prospectively.
