RESUMO
An 11-year-old spayed female pit bull terrier was presented with a 2-month history of polyuria, polydipsia, polyphagia, and panting. Serum chemistry, blood and urine analysis, and tests for hyperadrenocorticism suggested an adrenal tumor. Abdominal ultrasound identified a mass caudal to the right kidney. The mass was completely excised and histopathology was consistent with endocrine carcinoma. Three years later there was no evidence of recurrence or metastasis.
Carcinome surrénal ectopique fonctionnel chez un chien. Une chienne Pit-bull terrier stérilisée âgée de 11 ans a été présentée avec une anamnèse de 2 mois de polyurie, de polydipsie, de polyphagie et de halètements. La chimie sérique, l'analyse du sang et de l'urine et des tests pour hyperadrénocorticisme ont suggéré une tumeur surrénale. Une échographie abdominale a identifié une masse caudale au rein droit. La masse a été entièrement excisée et l'histopathologie était conforme à un carcinome endocrinien. Trois ans plus tard, il n'y avait aucune preuve de récurrence ni de métastase.(Traduit par Isabelle Vallières).

Intractable epistaxis can be a life-threatening condition. Surgical options are presently limited to ligation of the carotid artery. Extensive collateralization develops after occlusion of the carotid artery, so the benefits are likely only transient and the procedure cannot be repeated. In humans, endovascular treatment avoids many of the complications associated with surgery and has a lower recurrence rate than that associated with ligation of the internal maxillary artery. In 3 dogs with intractable epistaxis, embolization of the terminal portion of the maxillary artery was performed with polyvinyl alcohol particles and contrast slurry. Minor, self-limiting bleeding recurred in 1 dog 8 months after surgery; 2 dogs had no important complications or recurrence within a minimum 10-month follow-up time. Results indicate the feasibility of embolization of the terminal branches of the maxillary artery to control epistaxis in dogs that do not require surgery and as a useful adjunctive procedure prior to rhinotomy.
