[Cerebral salt wasting syndrome and traumatic vasospasm after head trauma: report of two cases].

While patients with cerebral salt wasting syndrome and traumatic cerebral arterial spasms have been reported, the underlying pathogenesis of these events remains unclear. We encountered 2 patients with head trauma and cerebral infarction who presented with cerebral salt-wasting syndrome and cerebral arterial spasms. Our findings suggested hypothalamic dysfunction due to venous congestion around the hypothalamus caused cerebral salt wasting syndrome and traumatic cerebral arterial spasms.
