Ventricular cardiac hemangiosarcoma with brain metastases in a dog

An 11-year-old, female, spayed, soft-coated Wheaten terrier presented for acute onset of neurological signs. On presentation, neurological examination showed right thoracic and pelvic limb proprioceptive deficits, absent right menace reflex, and weak right nasal septum response. A left thalamocortic...

Description
Summary:An 11-year-old, female, spayed, soft-coated Wheaten terrier presented for acute onset of neurological signs. On presentation, neurological examination showed right thoracic and pelvic limb proprioceptive deficits, absent right menace reflex, and weak right nasal septum response. A left thalamocortical lesion was localized. On thoracic auscultation, an arrhythmia was noted, and electrocardiography showed frequent ventricular premature complexes and rare runs of ventricular tachycardia. Echocardiography identified an interventricular septal mass extending into the lumen of the left ventricle. Thalamocortical metastasis secondary to the cardiac mass was suspected to be the cause of the patient's neurological signs. Humane euthanasia was elected by the owner due to the patients clinical status and poor prognosis. A postmortem examination diagnosed hemangiosarcoma of the interventricular septum, the right ventricular free wall, and left ventricular free wall. The left ventricle adjacent to the paraconal groove showed myocardial necrosis and inflammation. Metastases to the brain and secondary intracranial hemorrhage were found which were suspected to be the cause of the antemortem neurological signs. Concurrent pulmonary and hepatic metastases were noted. This report describes a rare presentation of an intracardiac hemangiosarcoma of the interventricular septum, right ventricle, and left ventricle in a patient presenting with neurological signs.
