Plain-English summary
A 13-year-old neutered male domestic shorthair cat was brought in with severe lethargy and excessive urination. The cat showed signs of brain issues, including slow heart rate and difficulty breathing, and tests indicated a possible pituitary tumor causing bleeding in the brain. After a couple of hours in the hospital, there was slight improvement, but the prognosis was uncertain. Sadly, the owner chose to euthanize the cat due to concerns about treatment options and outcomes.

Abstract
OBJECTIVE: To describe and discuss the unusual clinical presentation, novel imaging findings, and management of a cat with pituitary apoplexy and associated intraventricular hemorrhage. CASE SUMMARY: A 13-year-old neutered male domestic shorthair cat presented with semi-comatose mentation and marked polyuria. The menace response and pupillary light and vestibuloocular reflexes were absent, while the corneal reflex was maintained. The cat also had sinus bradycardia, hypoventilation, and hypothermia, indicating a multifocal brain lesion. The urine was hyposthenuric (urine specific gravity 1.003), and with increasing hypernatremia, central diabetes insipidus was suspected. After approximately 2 h in the hospital, there was mild improvement in neurological deficits and vital parameters. Computed tomography revealed a pituitary tumor with intralesional and extensive extralesional parenchymal and intraventricular hemorrhage. The cat was euthanized at the owner's request due to the uncertainty of treatment duration and outcome. NEW OR UNIQUE INFORMATION PROVIDED: This is the first reported case of suspected central diabetes insipidus in a dog or cat with PA and intraventricular hemorrhage; novel clinical and imaging findings are presented.
