[Adrenal ganglioneuroma].
We report a case of adrenal ganglioneuroma. A 29-year-old man was referred to our clinic for further investigation of right abdominal mass incidentally discovered by ultrasonography. Endocrinological study was unremarkable. Abdominal computed tomography revealed well-defined, 6-cm-long oval mass with mottled calcification. Adrenal scintigraphy showed enlarged adrenal gland with low accumulation. T1-image of magnetic resonance depicted hypointensity tumor in comparison with liver. Extirpation of this tumor disclosed yellowish white, homogeneous mass, 101 g in weight and 7 by 7 by 3.5 cm in diameter. Pathological diagnosis was ganglioneuroma. All reported cases of adrenal ganglioneuroma exceeded 5 cm in diameter. This indicates malignancy in computed tomography. Therefore, we should be careful in diagnosing ganglioneuroma.
