Acute adrenal necrosis in a young female cat

Abstract

AbstractCase DescriptionAn 18‐month‐old spayed female domestic short haired cat was presented for poor appetite, lethargy, exaggerated swallowing, and regurgitation 2 weeks after endoscopic retrieval of gastric foreign material.Clinical FindingsThe cat was quiet with tacky mucous membranes on physical examination. Point‐of‐care blood testing identified mild azotemia, moderate hypercalcemia, and a sodium‐to‐potassium ratio of 26. An ultrasound examination the next day identified moderate to marked bilateral adrenomegaly. Cytology of a fine needle aspirate of the adrenal glands was consistent with necrosis and associated inflammation. Hypoadrenocorticism was diagnosed by a confirmatory adrenocorticotropic hormone stimulation test.Treatment and OutcomeThe cat normalized both clinically and biochemically after treatment with prednisolone and desoxycorticosterone pivalate.Clinical RelevanceAcute adrenal necrosis has been well documented in human medicine after anesthetic events. To our knowledge, hypoadrenocorticism caused by cytologically confirmed acute adrenal necrosis has not been previously reported in dogs and cats.
