Abstract:
Objective To improve the diagnosis and treatment of ACTH-independent macronodular adrenal hyperplasia(AIMAH).Methods A 51-year-old female patient with Cushing's syndrome caused by AIMAH was reported.Elevated early morning plasma cortisol levels,increased 24 h urinary free cortisol excretion,and loss of the normal circadian rhythm in cortisol secretion were presented.There was no suppression of cortisol secretion by administration of low-and high-dose overnight dexamethasone suppression test.Cardio-pulmonary function was very bad with the highest blood pressure reaching 300/120 mm Hg( 1 mm Hg=0.133 kPa).Initially,she was treated with mitotane(60 mg/d),but was not effective.After taking ketoconazole (800 mg/d)for 5 days,cardio-pulmonary function was not effectively improved with blood pressure only descending to 180/120 mm Hg.Orthopnoea appeared and Spo2fell once to 75％.The patient had to undergo right total adrenalectomy immediately.ResultsThe mass resected was 10 cm× 10 cm in size and weighted 67.5 g.Histological examination of the removed adrenal revealed nonpigmented macronodular cortical hyperplasia.The patient continued to take ketoconazole (400-800 mg/d)from the 6th day of the operation without steroid replacement therapy in that period.With normal cortisol levels( plasma cortisol at 8:00 was 18.65 μg/dl,24 h urinary free cortisol was 78.75 μmol),she left hospital after the general condition had been improved.During the following updated 10 months follow up,the indexes of her laboratory examination were maintained normal.ConclusionIndividualized therapy should be adopted for the patient with AIMAH.The medication is useful to suppress the adrenal gland cortisol production for those with progression of symptoms,very high blood pressure,hypokalemia and hypoproteinemia.Once the cardio-pulmonary function improves,the target organ should be resected as soon as possible.The supplement of cortisol is not appropriate during the perioperative period.The unilateral adrenalectomy is an effective treatment for AIMAH.
