Abstract

We present a 7-year-old girl with a 2-year history of decelerated growth rate and cushingoidal obesity, upon admission presenting with fixed hypertension. Cyclic hypercortisolemia with inhibited baseline and post-CRH stimulation ACTH level pointed to primary adrenal hypercortisolemia. Ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) showed normal adrenal glands. ¹³¹J-labeled cholesterol scintiscan showed a weak but slightly more expressed tracer uptake in the left adrenal gland. Cushing syndrome concomitant with isolated primary pigmented nodular adrenocortical disease (PPNAD) was diagnosed. After hypotensive pretreatment, a left adrenalectomy was performed, resulting in normalization of corticoadrenal function, blood pressure, Cushing features and growth rate. Histopathology confirmed PPNAD. In the course of infection, corticoadrenal function showed absence of adrenal reserve, and adrenal crisis. Hydrocortisone (HC) therapy, followed by HC supplementation was introduced. Four years later, a contralateral adrenalectomy was performed and total HC supplementation was introduced. Causes and consequences of abandoning one-stage bilateral adrenalectomy recommended in PPNAD are reviewed.
