A 18-month-old Persian cat was presented after being hit by a car. Sur
gery was performed to correct a luxated hip. Eight weeks after the ini
tial accident, the cat became depressed and anorexic. A diaphragmatic
hernia was detected and surgically repaired. Post-operatively, the cat
remained depressed, which was exacerbated with discontinuation of its
intravenous fluids. Haematology and serum biochemistry suggested a di
agnosis of hypoadrenocorticism. Subsequent serum cortisol and ACTH mea
surements and the response to treatment confirmed the diagnosis. The c
ause of hypoadrenocorticism was thought likely to be due to previous t
rauma to the adrenal glands or to their blood supply.
