Retroperitoneal hemangiosarcoma causing chronic hindlimb lameness in a dog.
The clinical, radiographic, ultrasonographic, computed tomographic, surgical and histopathological findings in a Boxer dog with retroperitoneal hemangiosarcoma are described in this study. A seven-year-old, male, castrated Boxer dog was referred for evaluation of chronic hindlimb lameness. The physical examination revealed muscle atrophy and sciatic nerve deficits. Radiography and ultrasonography revealed a caudodorsal abdominal mass. Computed tomography revealed that the mass involved the left margin of the L7 vertebra, lumbosacral canal, and lumbosacral plexus. At surgery, a large retroperitoneal haematoma was removed. Histopathology of amorphous tissue found near the haematoma was consistent with haemangiosarcoma. The owner declined any further treatment. Ten weeks after discharge, the dog was euthanatized due to collapse and haemo-abdomen.
