Prenatal diagnosis of occipital encephalocele by ultrasound scanning.

Fetal visualization in utero can be routinely accomplished using noninvasive ultrasound techniques that do not administer ionizing radiation. Image resolution with real time sonography is sufficient to demonstrate details of possible congenital central nervous system malformations before delivery. The case reported illustrates the advantages of advance warning in an infant with occipital meningoencephalocele for determining prognosis, planning delivery by cesarean section, and preparing for immediate neurosurgical repair.
