摘要
目的探讨新生儿室管膜下囊肿的超声表现、发病病因及临床转归。方法选择2010年8月～2011年5月在我院产科出生的368例新生儿,在产后24h内常规颅脑超声检查,探头轻放于新生儿头颅前囟,分别作冠状面和矢状面扫查,重点观察新生儿颅脑尾状核头部和丘脑交界处的室管膜下区域有无病变及超声表现。结果 368例新生儿共检出室管膜下囊肿28例(7.6%,28/368),足月产新生儿19例,(5.6%,19/28),早产新生儿9例,(30%,9/28)。其中23例呈典型超声表现:冠状面在新生儿侧脑室前角下方、旁矢状面在丘脑尾状核沟可见单个或多个小囊肿,囊壁菲薄,多个小囊肿呈"蜂窝状"或"葡萄串状";5例为室管膜下出血吸收后所致囊肿,超声表现为:冠状面在新生儿侧脑室前角下方、旁矢状面在丘脑尾状核沟可见中央为无回声、周边回声强且略厚的多个囊样结构。结论头颅超声可作为诊断新生儿室管膜下囊肿首选检查方法,可了解其病因及预后,为临床治疗提供依据。
Objective To investigate the ultrasonic manifestation, causes and clinical outcomes of neonatal subependymal cyst. Methods 368 newborns within 24 hours of postpartum were detected by ultrasound with a special probe of neonatal craniocerebral inspection. A series of coronal and sagittal scan were conducted tran anterior fontanel, which emphasized on the zone of subependymal bordering between head of caudate nucleus and thalamus, so as to find pathological changes and the ultrasonographic findings. Results In 365 newborns, we found 28（7.6%, 28/368） cases of subependymal cyst, 19 （5.6%, 19/28） were term infants and 9（30%, 9/28） prematures. Among those, 23 cases showed typical ultrasonographic findings that bellowing the anterior angle of latera ventricle single or multiple noechoareas could be seen by coronal scan, boundary clear and wall thin, with honeycomb grid grapecluster appearing in multiple ones. By sagittal scan, they could be detected in thalamus caudate nuclei ditch. 5 cases were cysts comed from absorption of subependymal bleeding. By coronal scan bellowing the anterior angle of latera ventricle and by sagittal scan in thalamus caudate nuclei ditch, multiple noe- choareas could be seen. Ultrasonogram showed anechoic in the center, hyperechoic around. Conclusion Craniocerebral ultrasonic can be used as the preferred examination to diagnose neonatal subependymal cyst, investigate the pathogeny and the prognosis, and provide the basis for the clinical treatment.
