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.
我们报告一例肾上腺神经节瘤。一名29岁男性因超声偶然发现右腹部肿块而被转诊至我院作进一步检查。内分泌学检查无异常。腹部计算机断层扫描显示一个边界清晰、长6厘米的椭圆形肿块，伴有斑点状钙化。肾上腺闪烁显像显示肾上腺增大且放射性摄取较低。磁共振成像的T1加权像显示肿瘤相对于肝脏呈低信号。切除的肿瘤为黄白色、质地均匀的肿块，重101克，直径为7×7×3.5厘米。病理诊断为神经节瘤。所有已报道的肾上腺神经节瘤病例直径均超过5厘米。这在计算机断层扫描中提示为恶性。因此，我们在诊断神经节瘤时应谨慎。
