Cotyledonoid dissecting leiomyoma (CDL) is a rare variant of uterine leiomyoma characterized by intramural dissection within the uterine corpus and a distinctive gross appearance resembling the cotyledons of the placenta. Despite their alarming, sarcomatous appearance both macroscopically and radiographically, these tumors are typically associated with bland histologic findings. Approximately 70 cases of CDL have been described in the literature. This case represents the second described case of CDL in pregnancy, the first in which a pregnancy was carried to term. A 28-year-old primigravid was incidentally found to have a massive, exophytic growth of the uterus on ultrasound with concomitant 14-week intrauterine pregnancy. The pregnancy was monitored with serial growth ultrasounds. She was delivered at 37 weeks via Cesarean section. After being lost to follow-up, the patient presented 2.5 years later with worsening abdominal fullness and persistent uterine mass.
