RESUMO
A 10-year-old intact male Norwich terrier dog was evaluated for progressive, intermittent increased respiratory effort. Thoracic radiographs, ultrasonography, and computed tomography were used to identify a caudodorsal thoracic extrapulmonary mass and the presence of pulmonary metastasis. Blood transfusion and stabilization measures were not successful and the patient died. Necropsy confirmed the origin of the mass to be the adventitial layer of the aorta and determined it to be hemangiosarcoma. This is a rare site for the primary lesion.
Hémangiosarcome péri-aortique primaire chez un chien. Un chien Norwich terrier mâle intact âgé de 10 ans a été évalué pour effort respiratoire intermittent accru progressif. Des radiographies thoraciques, une échographie et une tomodensitométrie ont été utilisées pour identifier une masse extrapulmonaire thoracique caudodorsale et la présence de métastases pulmonaires. Une transfusion de sang et des mesures de stabilisation n'ont pas eu de succès et le patient est mort. La nécropsie a confirmé l'origine de la masse comme étant la couche adventice de l'aorte et a déterminé qu'il s'agissait d'un hémangiosarcome. Il s'agit d' un site rare pour une lésion primaire.(Traduit par Isabelle Vallières).

An orbital sialocele developed in a dog following enucleation for protracted glaucoma. This eye had historically been treated for keratoconjunctivitis sicca by parotid duct transposition approximately 5 years previously, and the duct was ligated distally at the time of enucleation. One month following enucleation, the dog presented with a fluctuant conical-shaped swelling ventrolateral to the orbital socket. Surgical exploration revealed a dilated, fibrotic distal portion of the previously transposed parotid duct, and saliva, within the enucleated orbit. The distal portion of the duct and saliva-containing tissues from within the orbit were excised. The remaining proximal normal portion of the parotid duct was re-routed into the oral cavity. Clinicopathologic and histologic examination of the excised orbital contents and dilated portion of duct revealed a sterile sample of saliva and moderate chronic periductal fibrosis. At a 6-month re-evaluation there was no evidence of recurrence of the sialocele, and the parotid duct was functional.
