Massive cotyledenoid leiomyoma treated with uterine-conserving surgery.

OBJECTIVE: To describe and illustrate a massive cotyledenoid leiomyoma treated with uterine-conserving surgery. DESIGN: Case report. SETTING: Medical center. PATIENTS: A 39-year-old woman with a large abdominal mass and a magnetic resonance imaging scan showing a 28-cm multi-lobulated mass. INTERVENTIONS: Laparotomy and myomectomy. MAIN OUTCOME MEASURES: Recurrence and need for repeat surgery. RESULTS: No recurrence at 8 years of follow-up. CONCLUSIONS: Cotyledonoid leiomyomas are rare. These benign tumors may be suspected preoperatively based on MRI appearance. Frozen section suggests a benign process and uterine-conserving surgery may be successfully accomplished.
