Medical management of feline emphysematous hepatitis—A case report.

Key Clinical Message: Case report summary: A 9–year‐old male castrated domestic shorthair feline was presented to the emergency department with a chief complaint of constipation of 3‐day duration, decreased urination of 1‐day duration, vomiting, and hind limb weakness. Physical examination abnormalities included hypothermia, dehydration, and generalized paresis with inability to stand for a prolonged period of time. Abdominal ultrasonography showed pinpoint hyperechoic foci throughout the hepatic parenchyma, small gas foci circulating within the portal vasculature consistent with emphysematous hepatitis, and mild volume of ascites. Cytology of the ascites was consistent with inflammatory effusion. Hepatic cytology was consistent with mixed inflammation/hepatitis with no apparent cause for inflammation noted. Urine culture yielded a negative result. Surgical liver biopsy and culture were declined by the patient's family. Ultrasound changes were presumed to be most likely secondary to an ascending infection. [ABSTRACT FROM AUTHOR]
