Primary adrenal lymphoma causing hypoaldosteronism in a cat.

ABSTRACT:

Case summary

A 10-year-old, 5.1 kg (11.2 lb), male castrated cat was presented with signs of lethargy and decreased appetite at home after being previously healthy. Serum biochemical analysis identified normokalemia (5.1 mmol/l; reference interval [RI] 3.4-5.6 mmol/l) and severe hyponatremia (123 mmol/l; RI 145-158 mmol/l), with an Na/K ratio of 24 (RI 32-41). Baseline serum cortisol was low to normal, but serum aldosterone was markedly decreased with a pre-adrenocorticotropic hormone stimulation concentration of 13 pmol/l (RI 194-388 pmol/l) and post-adrenocorticotropic hormone stimulation concentration of 21 pmol/l (RI 277-721 pmol/l). Hematologic and biochemical analyses were otherwise unremarkable. Abdominal ultrasound revealed bilaterally enlarged adrenal glands with no other
