Uveodermatologic syndrome presenting with concurrent aseptic meningoencephalitis in a dog.

Canine uveodermatologic syndrome (UDS) resembles human Vogt-Koyanagi-Harada syndrome but typically lacks associated neurological signs. We report a 3-year-old Australian shepherd dog diagnosed with UDS following bilateral enucleation and histopathology. Twelve days postoperatively, neurological symptoms developed, including head tilt, circling, and deafness.

Emphysematous splenic torsion in a German shepherd dog.

A 9-year-old castrated male German shepherd dog was presented because of a 2-day history of lethargy and anorexia. Abdominal distention and free peritoneal fluid were noted on physical examination, which prompted radiographs revealing a large, soft tissue and stippled gas opaque structure in the right cranial abdomen. Computed tomography was used to further describe the structure and assess for comorbidities in the dog.

Hypodipsic hypernatremia after long-standing polydipsia in a cat with suspect neonatal head trauma.

A 16-month-old neutered male domestic shorthair cat weighing 2.7 kg was referred for further evaluation of acute generalized muscle weakness and paraparesis after a long-standing history of polyuria-polydipsia. The diagnosis of hypodipsic/adipsic hypernatremia relied on the key findings of absent spontaneous drinking despite hypernatremia and a hyperosmolar state (444.

Computed tomographic and bronchoscopic diagnosis of Oslerus osleri infection in a dog.

A 16-month-old Sarplaninac Shepherd cross dog presented for a 1-month history of a productive cough that was unresponsive to an empirical 10-day course of cephalexin. Thoracic computed tomography (CT) showed multifocal, well-defined, smoothly marginated, soft tissue attenuating, minimally contrast enhancing nodular airway mural thickenings protruding into the airway lumen in the caudal trachea and principal bronchi. These nodules were also visualized on bronchoscopy, and cytology revealed parasitic larvae consistent with Oslerus osleri.

Rapport de cas Surgical retrieval of a migrated vascular access port catheter in a dog.

A 4-year-old spayed female Boston terrier was diagnosed with a suspected meningioma involving the optic chiasm and resulting in vision loss. A vascular access port (VAP) was placed in the left medial saphenous vein to facilitate frequent anesthetic episodes for radiation therapy. Five days after placement, the VAP was nonfunctional with the silicone catheter still intact.

Extrahepatic biliary duct obstruction secondary to duodenal foreign bodies in 2 dogs.

Two dogs, a 5-year-old neutered male boxer dog and a 2-year-old neutered male Australian cattle dog, were evaluated for vomiting and inappetence. Both dogs were icteric on physical examination, and had hyperbilirubinemia, elevated liver enzymes, and inflammatory changes on diagnostic blood analysis. A proximal duodenal obstruction causing extrahepatic biliary duct obstruction (EHBDO) was suspected in both cases after diagnostic imaging was performed.
