title: Cranial vena cava aneurysm in a dog.
abstract: A 1.5-year-old mixed breed dog was presented for evaluation of arrhythmia and a cranial mediastinal density was noted on thoracic radiographs. The density was determined to be a cranial vena cava aneurysm based on ultrasonographic and angiographic testing. No treatment was initiated and the dog remains asymptomatic for the cranial vena cava aneurysm at 6 years of age. Although rare, cranial vena cava aneurysm should be a differential diagnosis for dogs with cranial mediastinal abnormalities on thoracic radiographs.
