Answer

Head CT scan or MRI is suggested in all patients with severe hypernatremia.

Traction on dural bridging veins and sinuses caused by movement of water from the brain and brain shrinkage can lead to intracranial hemorrhage, most often in the subdural space.

Hemoconcentration from total body water loss may lead to dural sinus thrombosis.

Imaging studies may indicate a central cause for hypernatremia.
