We present here a case of adrenal incidentaloma in a 35-year-old male. Imaging technology including magnetic resonance imaging (MRI) clarified that the tumor was heterogeneous, and large in size (9x7 cm), and that it originated from the left adrenal gland. MRI scans on T1-weighted sequence showed the tumor with a low signal intensity followed by rapid contrast enhancement, whereas those on T2-weighted sequence showed markedly increased intensity. The tumor was surgically removed, and pathologic diagnosis was well-differentiated ganglioneuroblastoma. Ganglioneuroblastoma in adults is extremely rare, with only about 30 cases documented in people over the age of 20 years.
