A full-term neonate was examined to have significant macrocephaly (>>97th percentile), widened cranial sutures and a large bulging anterior fontanelle (AF). A light-emitting diode source applied on the AF revealed asymmetrical cranial transillumination, predominantly on the right (figure 1A). He was alert with spontaneous movements of all limbs but had generalised upper motor neuron (UMN) signs of hypertonia and hyper-reflexia. These signs indicated raised intracranial pressure from a possible right hemispheric cystic lesion. Figure 1 (A) Cranial transillumination of the skull through the anterior fontanelle showing asymmetrical transillumination, affecting …

颅脑透照诊断脑积水

一名足月新生儿经检查有明显的大头畸形（>97%）、颅缝增宽和大的前囟（AF）凸出。应用在 AF 上的发光二极管源显示不对称的颅内透照，主要在右侧（图 1A）。他对所有四肢的自发运动保持警觉，但有全身性的上运动神经元 (UMN) 高张力和反射亢进的迹象。这些迹象表明可能是右半球囊性病变导致颅内压升高。图 1 (A) 通过前囟门的颅骨透照显示不对称透照，影响…
