Virilizing adrenal ganglioneuroma in a woman with subclinical Cushing syndrome.
OBJECTIVE
To describe a patient with a virilizing adrenal ganglioneuroma and subclinical Cushing syndrome.


METHODS
Detailed clinical, laboratory, radiologic, and pathologic findings are presented, and the pertinent literature is reviewed.


RESULTS
A 56-year-old postmenopausal woman was referred for evaluation of a 3.6- by 3.0-cm right adrenal mass, which had been diagnosed during a work-up for hirsutism. A bilateral oophorectomy done 2 months before the presentation failed to correct the elevated testosterone levels. On examination, she had severe hirsutism on her face, chest, back, and extremities, as well as male pattern baldness and clitoromegaly. Biochemical evaluation showed elevated total and free serum testosterone levels of 319 ng/dL (reference range, 20 to 70) and 78 pg/mL (reference range, 1 to 9), respectively, values in the adult male range. The serum dehydroepiandrosterone sulfate level was 117 microg/dL (reference range, 10 to 152), and the urine free cortisol was 10.4 microg/24 h (reference range, <45). A laparoscopic adrenalectomy revealed a 5.0-cm adrenal ganglioneuroma containing nests of adrenocortical cells. On the first day postoperatively, the serum cortisol level was <1.0 microg/dL. At 1 month after adrenalectomy, the total and free testosterone levels had declined to 16 ng/dL and 3.1 pg/mL, respectively. At 2 months postoperatively, normal results of a cosyntropin stimulation test (basal and peak cortisol levels of 13.6 and 20.0 microg/dL, respectively) indicated recovery of the hypothalamic-pituitary-adrenal axis.


CONCLUSIONS
To our knowledge, this is the first case report of a virilizing adrenal ganglioneuroma with this unique pathologic finding and concomitant subclinical Cushing syndrome.
