目的探讨新生儿颅骨骨膜下血肿的临床特点、CT影像变化及转归。方法回顾性分析2008年2月-2012年8月收治的15例经产道自然分娩所致新生儿颅骨骨膜下血肿骨化的临床特点、CT表现及其治疗。结果 15例新生儿颅骨骨膜下血肿均有头盆不称、胎位不正或器械助产史,左或右侧顶部隆起质硬包块,基底部范围4.5~7.6 cm,病程4周~3个月,期间未经任何治疗处理;CT表现12例呈“夹心饼征”样之双层颅板表现,3例血肿下颅骨内外板全层骨质部分吸收消失,骨膜下新生骨有替代颅骨形成新颅骨的趋势。结论新生儿颅骨骨膜下血肿大部分可自行吸收消散;4周后不能缩小消散,且基底部直径>4.5 cm的血肿易骨化,需及时治疗处理,避免形成头颅畸形,错过最佳治疗时机,增加治疗难度。
Objective To investigate the clinical features of neonatal subperiosteal hematoma, CT image changes and prognosis. Methods The clinical features, CT findings and treatment of 15 cases of subperiosteal hemangioma of the skull caused by spontaneous labor during the period from February 2008 to August 2012 were retrospectively analyzed. Results All the 15 cases of subperiosteal hematoma of newborn had skull evisceration, fetal malposition or midwifery history. The left or right side of the top of the bulging hard mass, the basal portion range 4.5 ~ 7.6 cm, duration of 4 weeks to 3 months , Without any treatment during the treatment; CT showed 12 cases of “sandwich pie syndrome ” double skull manifestations, 3 cases of hematoma under the skull bone plate partial absorption of the entire outer layer disappeared, subperiosteal new bone replacement skull New skull formation trend. Conclusion Most newborn subperiosteal hematoma of the skull can be absorbed and dissipated by itself. After 4 weeks, the hematoma can not be reduced and dissipated. The hematoma of the base diameter> 4.5 cm is easy to be treated and treated, avoiding the formation of the cranial deformity and missing the optimal timing. Increase the difficulty of treatment.
