Objective To describe the prenatal sonographic findings and pregnancy outcome of fetuses with transient occipital bone protuberance (TOBP). Methods Five fetuses with TOBP were identified at routine 14 to 15 weeks ultrasound. The sonographic examination was repeated during pregnancy and the neonates were examined after birth. Results The occipital bone protuberance disappeared by 24 weeks in all five cases, and the postnatal examination of the skull was normal. Conclusions Isolated TOBP is rare during early pregnancy. Ultrasound follow‐up is suggested and disappearance of the lesion can be expected in most, if not all the cases with normal skull at birth. Copyright © 2010 John Wiley & Sons, Ltd.
