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 (9×7 cm), and that it originated from the left adrenal gland. MRI scans on Tl-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.
