A 37-year-old male who complained of left upper abdominal pain was revealed to have a well demarcated ovoid tumor of the left adrenal gland upon ultrasonography (US). The tumor has a solid echo pattern and generally hypoechoic internal echo, but there was mildly heterogeneous hyperechoic area. Total excision of the tumor was performed. The tumor was firm, 10.0×6.0×6.0 cm in size and weighed 280 g. Its cut surface was smooth and yellowish white. Microscopically typical findings of the ganglioneuroma were found, indicating the persence of large ganglion cells in a fibrous stroma. Ganglioneuroma occurring in the adrenal gland is relatively rare, and this case is only the 55th to be reported in Japan. Over the past three years, 27.8% of all reported cases were diagnosed by US. Most of the cases had a homogeneous hypoechoic pattern, however, one-third of the cases showed a heterogeneous hyperechoic area, like that in our case.
