[Ganglioneuroma arising in the adrenal medulla: a case report].

We report a case of adrenal ganglioneuroma. A 33-year-old woman visited our clinic with a complaint of epigastralgia. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) revealed a round mass, 4 cm in diameter, in the left suprarenal fossa. Laboratory data including endocrinological study were normal except for a mild increase of urinary excretion of dopamine. Under the diagnosis of left non-functioning adrenal tumor, surgery was performed on August 9, 1996 through flank incision. The excised tumor was well-demarcated and weighed 36.6 g. The cut surface revealed an ash-colored round tumor surrounded by thin stretched adrenal tissue. Histological diagnosis of the tumor was a ganglioneuroma originating from the adrenal medulla.
