Radiography, Computed tomography angiography and ultrasonography were performed for evaluation of the volume and angiogenesis of the mass.Treatment and Outcome- Treatment was consist of surgical excision of the mass. The patient was fine up to 6 months after surgery, then recurrence at the same site was observed, therefore the owner requested for euthanasia.Clinical Relevance- In this record, we presented diagnostic imaging characteristics of a mass presumed at the injection site in a dog. Few records have been published in veterinary literature about injection site tumors in dogs, however, there are plenty of those in relation with feline injection-site sarcoma (FISS).}, keywords = {Haemangiopericytoma,CT-Scan angiography,Ultrasonography}, url = {https://www.ivsajournals.com/article_82923.html}, eprint = {https://www.ivsajournals.com/article_82923_6ac2832cf3849ed6ab2a4caef63a715a.pdf} }
