ABSTRACT
Ganglioneuroma (GN) is a rare benign tumor arising mainly from neural crest cells and consisting of Schwann and ganglion cells. GN rarely occurs from the adrenal medulla and is observed most commonly in children and young adults. It is not associated with hormonal activity and is clinically asymptomatic. We present a 35-year-old woman whose abdominal ultrasonography for abdominal pain revealed in the rightadrenal gland, a biochemically normal mass that was minimally hypointense on T1-weighted and hyperintense on T2-weighted magnetic resonance images (MRI) and which was pathologically diagnosed as GN after adrenalectomy.
