Ultrasound brain scans sometimes demonstrate increased echogenicity or cysts, or both, in the periventricular white matter, superolateral to the ventricle, in the most common site of periventricular infarction. Over 33 months, 23 preterm infants dying after 20 or more days of life were entered into this study. Superolateral echogenicity or cysts were found in 13 (57%) cases. Periventricular infarction was present at autopsy in 12 (52%) cases. Ultrasound accurately diagnosed the size, site, and extent of periventricular infarction in 78% of scans. Interpretive errors were made with poor-quality scans and with early and late studies. We conclude that sector ultrasound brain scans accurately diagnose major periventricular infarction. Hemorrhage into the site of infarction is not a prerequisite for diagnosis of periventricular infarction by ultrasound.
超声脑部扫描有时会显示，在脑室周围梗死最常见的部位，即脑室上方外侧的脑室周围白质中，回声增强或出现囊肿，或两者皆有。在33个月的时间里，23名出生20天或更长时间后死亡的早产儿被纳入本研究。13例（57%）发现脑室上方外侧回声增强或有囊肿。尸检发现12例（52%）存在脑室周围梗死。在78%的扫描中，超声能准确诊断脑室周围梗死的大小、部位和范围。扫描质量差以及早期和晚期检查会出现解读错误。我们得出结论，扇形超声脑部扫描能准确诊断主要的脑室周围梗死。梗死部位出血并非超声诊断脑室周围梗死的必要条件。
