Parasitic Intraperitoneal Leiomyoma causing Right Hydronephrosis and Flank Pain

Abstract

Uterine leiomyomas are the most common benign pelvic tumors in female patients, occurring in approximately 25% of women of reproductive age [1–3]. Parasitic leiomyomas are unusual variants of pedunculated leiomyomas that attach to peritoneal surfaces, distinct from the uterus in the abdominal cavity, subsequently lose their myometrial blood supply, and survive by obtaining a blood supply from neighboring organs [1,3]. Another thought is that parasitic leiomyomas may originate from myoma fragments left in the peritoneal cavity after uterine morcellation during laparoscopic or open myomectomy or hysterectomy [2,4].
