The premature infant brain has been thoroughly studied by sonography, and normal standards for ventricular size have been established. Whether these apply to normal full-term infants is uncertain. Fifty-three healthy full-term infants were electively examined by real-time sonography through the anterior fontanelle on the first to sixth days of life. Nine had asymmetric lateral ventricles; two of these had unexpected evidence of intracranial hemorrhage, while a third had a ventricular cyst. Forty-four infants had symmetric ventricles, but in 36 the ventricles had little or no cerebrospinal fluid. Vaginal delivery had a statistically significant association with these "compressed' lateral ventricles. This study indicates that seemingly healthy infants may have unsuspected intracranial hemorrhage, that asymmetric ventricular size may be normal, and that shortly after birth most healthy infants have "compressed" lateral ventricles that should not be interpreted as cerebral edema.
超声检查已对早产儿脑部进行了全面研究，并确立了脑室大小的正常标准。这些标准是否适用于正常足月儿尚不确定。对53名健康足月儿在出生后第1至6天通过前囟进行实时超声检查。9名婴儿侧脑室不对称；其中2名有意外的颅内出血迹象，另1名有脑室囊肿。44名婴儿脑室对称，但其中36名脑室几乎没有或没有脑脊液。阴道分娩与这些“受压”侧脑室有统计学上的显著关联。本研究表明，看似健康的婴儿可能有未被怀疑的颅内出血，侧脑室大小不对称可能是正常的，而且大多数健康婴儿在出生后不久有“受压”的侧脑室，不应将其解释为脑水肿。
