Hypoadrenocorticism in a young dwarf cat - case report

A 8-month-old cat with immature appearance was referred as an emergency, showing lethargy, weakness, anorexia and dehydration. The case history reported two months of apparently neurologic disorders with behavioral changes and waxing-waning clinical course, including temporary remissions associated with parenteral fluid and/or corticosteroid administration. Clinical examination revealed hypovolemic shock, extreme weakness, severe hypothermia, and bradycardia. Laboratory profile revealed several abnormalities consistent with hypoadrenocorticism. After clinical stabilization, an adrenocorticotropic hormone (ACTH) stimulation test was performed, confirming the suspicion. The cat had a rapid decline and died. Probably, previous diagnostic errors and inappropriate treatments compromised the outcome of therapy. We emphasize the importance of early diagnosis in a disease that, although rare in this species, should not be overlooked in the differential diagnosis.
