Although ganglioneuroma is a relatively rare tumor of the sympathetic nervous system, detection of this tumor has increased as imaging techniques such as computed tomography and ultrasonography have become prevalent. We report 2 cases of ganglioneuroma found incidentally. Both tumors were 40 to 60 mm in size. Magnetic resonance imaging in 1 patient showed a homogeneous mass with a low signal intensity on T1-weighted imaging and a heterogeneous mass with a high signal intensity on T2-weighted imaging, both characteristic of neurogenic tumor. Therefore, we performed laparoscopic adrenalectomy. Histopathologic examination demonstrated that one tumor was located on the adrenal medulla, with the other in the extra-adrenal retroperitoneal space.
虽然神经节神经瘤是一种相对罕见的交感神经系统肿瘤，但随着计算机断层扫描和超声等成像技术的普及，这种肿瘤的检出率有所增加。我们报告2例偶然发现的神经节神经瘤。两个肿瘤大小均为40至60毫米。1例患者的磁共振成像显示，在T1加权成像上为均匀低信号强度肿块，在T2加权成像上为不均匀高信号强度肿块，均为神经源性肿瘤的特征。因此，我们进行了腹腔镜肾上腺切除术。组织病理学检查表明，一个肿瘤位于肾上腺髓质，另一个位于肾上腺外腹膜后间隙。
