A 28\u2010year\u2010old woman presented with decreased fetal movements at 38\u2009weeks of gestation. Due to a nonreassuring fetal heart rate pattern, an emergency cesarean section was performed. Severe neonatal anemia (3.2\u2009g\/dL) and markedly elevated maternal serum alpha\u2010fetoprotein levels suggested FMH, despite normal maternal hemoglobin F levels. Initial placental pathology was unremarkable. Thirteen days postpartum, the patient developed massive vaginal bleeding requiring uterine artery embolization (UAE). Elevated serum \u03b2\u2010hCG levels and multiple pulmonary nodules led to a clinical diagnosis of choriocarcinoma. Placental re\u2010evaluation confirmed ICC. Chemotherapy with methotrexate, etoposide, and actinomycin D resulted in complete remission. In conclusion, ICC should be considered in cases of unexplained FMH or postpartum hemorrhage. UAE did not appear to impair the efficacy of subsequent chemotherapy in this case.<\/jats:p>","DOI":"10.1111\/jog.70463","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T00:42:07Z","timestamp":1786668127000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Intraplacental
