Fetal cephalhematoma - an unusual antenatal presentation of a common neonatal scalp swelling posing a diagnostic challenge.

Cephalhematoma is an accumulation of blood in the subperiosteal space. While cephalhematoma is a well-documented postnatal occurrence, antenatal presentation is quite rare. This case report focuses on a rare presentation of fetal scalp swelling in a routine 32-week antenatal scan of a 38-year-old female. The swelling resolved spontaneously after birth. Awareness of this atypical manifestation is crucial for the radiologist to consider it in the differentials and for the obstetrician in providing appropriate prenatal care and avoiding unnecessary drastic interventions. The aim is to elucidate the diagnostic challenges and clinical management of this unique presentation.
