Erosion of calcified uterine leiomyoma into the urinary bladder: A case report

Abstract

Introduction: Uterine leiomyomas are benign smooth muscle tumors that affect approximately 70–80% of women worldwide. Erosion of leiomyomas into surrounding tissues is a rare complication. We present a case of a postmenopausal female with uterine leiomyoma eroding into the urinary bladder. Case Report: A 55-year-old, postmenopausal female with history of uterine fibroids previously treated with uterine artery embolization presented with recurrent bladder stones, hematuria, and pelvic pain. Pelvic magnetic resonance imaging described a 4.3 cm heterogenous mass involving the ventral uterine fundus and bladder dome concerning for malignancy. She underwent robotic-assisted total laparoscopic hysterectomy, right salpingo-oophorectomy, left salpingectomy, and partial bladder cystectomy. Pathology was significant for benign calcified leiomyoma and benign calcifications within the bladder mucosa. Conclusion: Erosion of leiomyoma through the bladder mucosa is rare complication but should be considered in the differential diagnosis for patients presenting with hypercalciuria and recurrent bladder stones in the setting of uterine fibroids previously treated with uterine artery embolization.
