Emphysematous cystitis (EC) and emphysematous pyelonephritis (EPN) are the result of infection of the urinary bladder and kidneys by gas-producing microorganisms. Those infections are most often reported in diabetic patients and rarely occur concurrently. This article describes two cases of concurrent EC and EPN, one in a nondiabetic dog and the other in a diabetic cat. The use of diagnostic imaging is necessary in the diagnosis of emphysematous infections. Both radiography and ultrasonography were used in the diagnosis of EC and EPN in the patients described in this report.

Objective: To create a chart for estimating body surface area (BSA) for use in canine burn victims, similar to the human Rule of Nines.

An 8-year-old neutered male Toy Poodle was presented with chronic, progressive tetraparesis, and possible seizures. Magnetic resonance images demonstrated an extensive, T1 and T2 hyperintense contrast enhancing mass in the cervical spinal cord. Three nodules were present on the surface of the thalamus, with enhancement most evident on delayed images. A diagnosis of high-grade oligodendroglioma was confirmed with postmortem histopathology and immunohistochemical labeling. Oligodendroglioma should be considered as a differential for T1 hyperintense intraaxial or intramedullary lesions with contrast enhancement. If enhancement is not visualized on postcontrast images, delayed images may be beneficial.
