A 9‐year‐old male Appenzeller mountain dog had progressive severe ataxia and central vestibular syndrome that was localized clinically to the brain stem. The cerebrospinal fluid characteristics were suggestive of hemorrhage into the subarachnoid space. On computed tomography (CT), hyperattenuating masses were found in the left lateral ventricle extending into the cerebrum, and another involving the cerebellum and brainstem. The hyperattenuation of the masses in noncontrast images and the absence of contrast enhancement were consistent with hemorrhage. The dog underwent euthanasia. A metastatic hemangiosarcoma in the brain, causing acute bleeding in the left lateral ventricle and the brainstem, was found. A solitary mass in the left myocardium was thought to be the primary site. CT characteristics of intracranial hemorrhage are reviewed.
