Spontaneous vaginal expulsion of an infected necrotic cervical fibroid through a cervical fistula after uterine artery embolization: a case report

BACKGROUND: Uterine artery embolization (UAE) is promising, minimally invasive therapy being offered to women for treatment of fibroids. Although it seems to be safe and effective, major complications and adverse outcomes have been reported. CASE: A patient treated with UAE for a huge cervical fibroid presented with an infected, necrotic cervical mass lesion 4 weeks after the procedure. Spontaneous vaginal expulsion of the infected cervical fibroid from the left lateral cervical fistula tract occurred 3 weeks later while the patient was receiving antibiotic therapy. After 6 months of intervention, an approximately 99% regression rate in the fibroid volume was achieved. The patient gave birth to a healthy, female infant following a spontaneous, uneventful pregnancy and vaginal delivery. CONCLUSION: UAE appears to be associated with a significant reduction in fibroid volume. Expulsion of the infected, necrotic parts of the fibroid after UAE may be accepted as a natural process. Warning the patient about this potential risk, early recognition of infective complications and lose follow up seem to be crucial to avoiding potentially fatal septic shock.
