Multimodality imaging of primary ureteral hemangiosarcoma with thoracic metastasis in an adult dog.

A 12-year-old spayed female standard Poodle was presented for investigation of severe hematuria. Abdominal ultrasound and thoracic and abdominal computed tomography identified severe hydronephrosis due to an obstructive ureteral mass with no evidence of metastasis. Histological examination after nephrectomy and ureterectomy confirmed an obstructive ureteral hemangiosarcoma.

An optimized protocol for multislice computed tomography of the canine brain.

Computed tomography (CT) is commonly used in veterinary practice to evaluate dogs with suspected brain disease, however contrast resolution limitations and artifacts may reduce visualization of clinically important anatomic features. The purpose of this study was to develop an optimized CT protocol for evaluating the canine brain. The head of a 5-year-old Springer Spaniel with no neurological signs was imaged immediately following euthanasia using a 4-slice CT scanner and 282 protocols.

Imaging diagnosis-ultrasonographic and CT findings in a gray seal (Halichoerus grypus) with hepatic cirrhosis, pyelonephritis, and nephrolithiasis.

An immature gray seal was presented with lethargy, weight loss, vomiting and hematuria. Hepatic disease and urinary tract infection were suspected. Abdominal ultrasound showed hyperechoic structures with marked acoustic shadowing spread throughout both kidneys, but incomplete visualization of the liver.

Geographical, clinical, clinicopathological and radiographic features of canine angiostrongylosis in Irish dogs: a retrospective study.

Background: Angiostrongylus vasorum infection is associated with high morbidity and mortality in dogs. Although recognised in Ireland, there are no large series of cases reported. The aim of this retrospective study was to identify pertinent clinical and geographical features in Irish dogs.

Imaging diagnosis: CT findings in a dog with intracranial hemorrhage secondary to angiostrongylosis.

A seven-month-old Cocker Spaniel had a cough, acute lethargy, decreased responsiveness, and episodes of hyperexcitability. There were bilateral generalized increased lung sounds, bilateral episcleral hemorrhage, and systemic hypertension. Prolonged buccal mucosal bleeding time and elevated D-dimer concentrations were detected.
