Histologic examination diagnosed an extremely rare primary aortic chondrosarcoma in a 14-year-old dog presenting with acute hindlimb paresis and an intraluminal aortic mass.
Case Report (n=1)
Primary aortic chondrosarcoma should be considered in the differential diagnosis of dogs presenting with an intraluminal aortic mass and acute hindlimb paresis mimicking thromboembolism.

May warrant inclusion in differentials for canine aortic masses with paresis; single case leaves open prevalence and management questions.
A 14-year-old, mixed breed dog was presented with acute pain and paresis of the hindlimbs. Ultrasonography revealed an intraluminal mass and an abrupt halt of blood flow signal in the distal abdominal aorta. The mass had homogeneous hyperechoic echotexture compared with blood flow. Although clinical presentation suggested a thromboembolism and pituitary dependent hyperadrenocorticism was suspected as a predisposing cause based on adrenal function tests and ultrasonography, an aortic chondrosarcoma originating from the distal abdominal aorta was diagnosed with histologic examination. Primary aortic sarcoma is extremely rare, and extraskeletal chondrosarcoma is only reported in 2 cases previously. Aortic neoplasm should be included in differential diagnosis when an intraluminal aortic mass is observed on ultrasonography and acute paresis of hindlimbs is shown.
