Placenta accreta: an association with fibroids and Asherman syndrome.

OBJECTIVE: Placenta accreta is a life-threatening problem that is rising in incidence in the developed world. The increased risk of placenta accreta in women with placenta previa and 1 or more prior cesarean deliveries is well established and prompts careful sonographic evaluation. Our objective was to emphasize that accreta is also identified at sites other than cesarean scars. METHODS: Two cases of placenta accreta without placenta previa seen in association with uterine scarring from myomectomy and uterine fibroids are described. RESULTS: The sonographic and magnetic resonance imaging findings of accreta are reviewed in the classic setting of prior cesarean deliveries as well as myomectomy and uterine fibroids. CONCLUSIONS: We suggest that when the placenta overlies any uterine abnormality, a careful search for invasive placentation is warranted.
