Management of dystocia caused by a large sacrococcygeal teratoma.

Sacrococcygeal teratoma is a rare cause of dystocia. Reported management strategies to date have yielded few viable infants. In this case report, the infant was partially delivered when extraction was halted. The infant was intubated and resuscitated while preparations for emergency cesarean section were being made. The infant was subsequently delivered abdominally and three years later is normal. Despite absent thoracic cage movement during resuscitation, adequate oxygenation was possible. Increasing use of prenatal ultrasonography should allow early detection, and thus avoid such unanticipated dystocias.
