The majority of neonatal cases (90%) result from applying a vacuum to the head at delivery (ventouse-assisted delivery). The vacuum assist ruptures the emissary veins (i.e., connections between dural sinus and scalp veins) leading to accumulation of blood under the aponeurosis of the scalp muscle and superficial to the periosteum. Additionally,<unk>  hematoma has a high frequency of occurrence of associated head trauma (40%), such as intracranial<unk>  or skull fracture. The occurrence of these features does not correlate significantly with the severity of<unk> .
