腎上腺皮質腫瘤自主性分泌過量醛固酮，導致低血鉀和全身性高血壓的內分泌疾病。是貓最常見的腎上腺皮質疾病，多為單側腎上腺腺瘤或腺癌。因初始症狀不特異，常被延遲診斷。
Cats may present with subtle clinical signs; behavioral changes (hiding, decreased interaction, altered grooming) often indicate illness. Stress-related conditions (FLUTD, feline hyperesthesia, psychogenic alopecia) are common. Geriatric cats should be screened annually for CKD, hyperthyroidism, and hypertension.
Clinical presentation in dogs varies significantly by breed, age, and body condition. Breed predispositions should guide differential diagnosis and screening protocols. Concurrent medications and diet (especially grain-free diets linked to DCM investigation) should be assessed.

口服補鉀矯正醛固酮過量導致的低血鉀性肌病
建議：依臨床狀況調整
監測頻率：依病因
建議數日內就診評估，非立即危及生命但不宜拖延 (evaluation within days recommended, not immediately life-threatening)
手術切除腺瘤的預後良好，多數貓術後低血鉀和高血壓可完全緩解且不需長期用藥。腺癌的預後較差但術後仍可能獲得數月至數年的良好生活品質。未治療的持續性高血壓將導致不可逆的靶器官損傷（失明、腎衰竭）。內科管理可有效控制但需終身用藥。
原發性高醛固酮症 診斷流程
老年貓出現低血鉀、高血壓或肌肉無力
測定血清醛固酮濃度和腎素活性
腹部超音波或CT掃描腎上腺
補鉀降壓穩定後行腎上腺切除術
