Diagnoses Polyphasia Polyphasia Possible hyperadrenocorticism - elevated ALT, ALKP and hypercholesteraolemia Possible hyperadrenocorticism - elevated ALT, ALKP and hypercholesteraolemia Lipemia despite fasting –elevated triglycerides and cholesterol Lipemia despite fasting –elevated triglycerides and cholesterol Proteinuria Proteinuria Abdominal/thoracic masses/prominent lymph nodes Abdominal/thoracic masses/prominent lymph nodes

Assessment Clinical signs of polyphagia and polyuria in conjunction with elevated liver enzymes (ALT and ALKP), hypercholesterolemia, ACTH stim. test and the ultrasound findings are suggestive of hyperadrenaocorticism Clinical signs of polyphagia and polyuria in conjunction with elevated liver enzymes (ALT and ALKP), hypercholesterolemia, ACTH stim. test and the ultrasound findings are suggestive of hyperadrenaocorticism Leads to hyperactivity of adrenal glandLeads to hyperactivity of adrenal gland Benign tumor of pituitary or tumor of adrenal glandBenign tumor of pituitary or tumor of adrenal gland

Assessment continued Persistant proteinuria and lipemic plasma protein causing an elevated triglyceride level is also consistant with hyperadrenocorticism Persistant proteinuria and lipemic plasma protein causing an elevated triglyceride level is also consistant with hyperadrenocorticism Elevated urine cortisol/creatinine ratio also supportive of hyperadrenocorticism, but also consistant with neoplasia, hyperthyroidism and stress Elevated urine cortisol/creatinine ratio also supportive of hyperadrenocorticism, but also consistant with neoplasia, hyperthyroidism and stress

Assessment continued Abdominal ultrasound is supportive of hyperadrenocorticism as the primary ruleout Abdominal ultrasound is supportive of hyperadrenocorticism as the primary ruleout No evidence of neoplasia or metastatic disease on either the ultrasound or radiographs No evidence of neoplasia or metastatic disease on either the ultrasound or radiographs Thoracic and abdominal radiographs revealed orthopedic disease including spondylosis and DJD of shoulders and hip dysplasia with secondary DJD Thoracic and abdominal radiographs revealed orthopedic disease including spondylosis and DJD of shoulders and hip dysplasia with secondary DJD
