BACKGROUND AND PURPOSE
Scalp swelling associated with cranial burst fracture, a widely diastatic skull fracture of infants associated with dural laceration and acute cerebral extrusion, may be confused with that of a simple subgaleal hematoma. Both conditions can also be associated with hemorrhagic shock. We sought to improve the early evaluation of infants believed to have sustained cranial burst fracture by including MR imaging, since this study clearly delineates the dural-cortical interface, the site of injury.
METHODS
Seven infants aged 1 through 11 months who sustained cranial burst fractures, all initially imaged with skull radiography and CT, were studied or treated from 1992 through 1996. MR imaging was obtained after resuscitation and stabilization.
RESULTS
Surgery or autopsy confirmed MR findings (dural laceration and extracalvarial cerebral tissue) in all seven infants.
CONCLUSION
MR imaging allows early diagnosis of skull fracture associated with acute cerebral extrusion.
背景与目的
颅骨爆裂骨折相关的头皮肿胀，是一种与硬脑膜撕裂和急性脑膨出相关的婴儿广泛分离性颅骨骨折，可能会与单纯帽状腱膜下血肿相混淆。这两种情况也都可能与失血性休克有关。我们试图通过纳入磁共振成像（MR成像）来改善对疑似颅骨爆裂骨折婴儿的早期评估，因为这项研究能够清晰地描绘硬脑膜 - 皮质界面，即损伤部位。
方法
对1992年至1996年期间7例年龄在1至11个月、发生颅骨爆裂骨折的婴儿进行研究或治疗，所有婴儿最初均行颅骨X线摄影和CT检查。复苏和病情稳定后进行MR成像检查。
结果
手术或尸检证实了所有7例婴儿的MR成像结果（硬脑膜撕裂和颅外脑组织）。
结论
MR成像能够早期诊断与急性脑膨出相关的颅骨骨折。
