Ganglioneuroma Manifesting as an Incidental Adrenal Mass in an Adult With Turner’s Syndrome

Abstract

To report a case of ganglioneuroma masquerading as an incidental adrenal mass in an adult patient with Turner's syndrome. We present the clinical, laboratory, radiologic, and pathologic findings in this patient. A 31-year-old woman with Turner's syndrome who had previously been treated with growth hormone replacement had an incidentally discovered mass, apparently arising from the left adrenal gland. The mass was "silent" clinically and biochemically, but imaging characteristics were not reassuring for a benign cortical adenoma. Because of uncertainty regarding the nature of the mass, it was removed laparoscopically; during this procedure, it was noted to be intimately associated with, but anatomically distinct from, the left adrenal gland. The pathology report confirmed the presence of a benign ganglioneuroma. Although ganglioneuroma has previously been noted to be associated with Turner's syndrome (especially in pediatric patients), to the best of our knowledge this is the first report of a ganglioneuroma manifesting as an incidental adrenal mass in an adult patient with Turner's syndrome.
