Serial cranial ultrasonography was performed in 17 preterm infants with periventricular leukomalacia (PVL) in the neonatal period. Periventricular high-echogenicities were observed in all infants, and periventricular cysts in 14/17 infants (82%). We investigated the correlation between these findings and abnormalities on MRI in late infancy. Periventricular high-echogenicity was correlated with the extent of periventricular high-intensities on T2-weighted images of late infantile MRI. The extent of periventricular cysts was correlated with that of volume loss on MRI during late infancy. The degree of periventricular echo-lesion was associated with that of neurological abnormalities of infants. The extent of periventricular echo-lesion has the same prognostic value as findings on MRI in infants with PVL.
对17例新生儿期患有脑室周围白质软化症（PVL）的早产儿进行了系列头颅超声检查。所有婴儿均观察到脑室周围高回声，14/17例婴儿（82%）观察到脑室周围囊肿。我们研究了这些发现与婴儿晚期MRI异常之间的相关性。脑室周围高回声与婴儿晚期MRI T2加权图像上脑室周围高强度的范围相关。脑室周围囊肿的范围与婴儿晚期MRI上体积丢失的范围相关。脑室周围回声病变的程度与婴儿神经异常的程度相关。脑室周围回声病变的范围与PVL婴儿MRI检查结果具有相同的预后价值。
