Plain-English summary
A 10-year-old male dog and a 7-year-old female dog, along with a 5-year-old male cat, were brought in with severe neurological symptoms like lethargy and coordination problems. They were diagnosed with issues related to their central nervous systems, including a pituitary gland tumor in one dog and brain trauma in the cat. Blood tests showed dangerously high sodium levels, which can be life-threatening. Unfortunately, both dogs had to be euthanized due to their poor prognosis, but the cat survived after treatment.

Abstract
Hypernatremia due to different pathophysiological mechanisms results in a rise in plasma osmolality. Dependent on its severity and on the speed of its development hyperosmolality can be life-threatening. This article describes 2 dogs and 1 cat with central nervous system disorders (adenoma of the pituitary gland, cerebral trauma). All patients developed normovolemic hypernatremia due to pituitary gland and hypothalamus dysfunction, respectively. Plasma sodium concentrations ranged from 163 to 185 mmol/l. Neurological examinations revealed lethargy, disturbances of consciousness, and ataxia, respectively. The dogs had to be euthanased due to the grave prognosis, the cat with cerebral trauma survived.
