Emphysematous cystitis in a non-diabetic cat with Staphylococcus spp.

Emphysematous cystitis (EC) is uncommon infection of urinary tract which is characterized by air within the bladder wall and lumen. A 3 years old male cat presented with polyuria/polydipsia, lethargy, and inappropriate urination. Temperature, pulse and respiratory rates were within normal limits on physical examination. Blood work revealed leukocytosis and increased levels of blood urea nitrogen and creatinine. Urinalysis revealed persistent proteinuria in urine dipstick and bacteria under microscopical examination of urine. The presence of air in the bladder were seen in latero-lateral abdominal view. Based on lab work and imaging abnormalities, a diagnosis of emphysematous cystitis was made. The use of diagnostic imaging and lab work are necessary in the diagnosis and treatment of this rare disease, and will be described in this report.
