Torsion of an iatrogenic parasitic fibroid related to power morcellation for specimen retrieval.

Parasitic fibroids are generally diagnosed incidentally at the time of surgery performed for symptomatic uterine fibroids. Torsion of a parasitic fibroid causing severe acute onset pain is extremely rare. We report a torsed parasitic fibroid in a patient who underwent hysterectomy using power morcellation for specimen retrieval. A 40-year-old patient with a history of laparoscopic supracervical hysterectomy 8 years prior presented with severe abdominal pain. She was diagnosed with degenerating parasitic fibroids on magnetic resonance imaging and was managed conservatively. Surgery was performed 3 days later for persistent pain, and the parasitic fibroid was found to have undergone torsion. Torsed ischemic fibroids can undergo necrosis and gangrene and can potentially cause life-threatening coagulopathy and peritonitis. Awareness of this potential complication will reduce errors in diagnosis and facilitate timely management.
