Abstract

A 10-year-old castrated male mixed-breed dog exhibited vomiting, lethargy and anorexia. An abdominal ultrasound examination revealed a focal dilation of the abdominal aorta. The dog died 2 days after examination, and necropsy revealed a ruptured aneurysm at the abdominal aorta between the kidneys. Histological examination revealed severe granulomatous and necrotizing pan-arteritis with fungal organisms. Graphium species was identified through DNA sequence analysis of the PCR product from formalin-fixed paraffin-embedded samples. To our knowledge, this is the first report of aortic aneurysm caused by Graphium species in a dog.
