Signalment • Canine, Schipperke mix • Female, Spayed • 12 years old
History • Significantly increased appetite over past year • PU/PD
Physical Exam • Abdomen: Hepatomegaly palpated • PLN: Prominent axillary lymph nodes • Integument: Scaling noted • All other parameters within normal limits
Diagnostic Tests • CBC: plasma protein lipemic, no other abnormalities noted • Biochemistry: hypercholesterolemia (397 MG/DL, rr=138-317), elevated alkaline phosphatase (637 IU/L, rr=14-120), ALT (204 IU/L, rr=16-73), elevated creatine kinase (1314 IU/L, rr=48-380) • Urinalysis: 3+ protein, specific gravity 1.022 (rr=1.015-1.045)
Diagnostics continued • Elevated urine cortisol/creatinine ratio • Urine culture • Triglyceride level: mildly elevated (218 MG/DL, rr=19-133) • ACTH Stimulation Test: -base line=7.5 UG/DL, post=27.3 UG/DL • FNA of right axillary lymph node
Radiographs • Spine-Lumbosacral: • bilateral hip dysplasia with secondary degenerative joint disease • L6-7 and L7-S1 spondylosis deformans
Radiographs • Thoracic: • spondylosis deformans • shoulder degenerative joint disease • no evidence of pulmonary metastatic disease
Abdominal Ultrasound • Hepatic hyperechogenicity, as with pronounced vacuolar changes • Hyperechoic nodule in midregion of spleen • Bilateral adrenomegaly • Small splenic nodules, likely benign • Gallbladder sediment
Diagnoses • Polyphasia • Possible hyperadrenocorticism -elevated ALT, ALKP and hypercholesteraolemia • Lipemia despite fasting –elevated triglycerides and cholesterol • Proteinuria • 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 • Leads to hyperactivity of adrenal gland • Benign 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 • 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 • 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
