Abstract
We report a case of a 31-year-old man with multiple ganglioneuromas in the retroperitoneum. Unenhanced abdominal CT images showed a large tumor with punctate calcification and a small tumor in the right retroperitoneum, both of which had homogeneous low attenuation. Dynamic CT images showed that both had minimal enhancement at the early phase. MRI images demonstrated the large one with heterogenous high signal intensity on T2-weighted images and inhomogenous gradual enhancement on dynamic images and the small one with homogenous low signal intensity on T2-weighted images and hypervascularity on dynamic images. Histopathological study confirmed that both were compatible with ganglioneuroma, consisting of ganglion cells, Schwann cells, nerve fibers, collagen and myxoid stroma. There was abundant myxoid stroma and less cellular component in the central part of the large one. On the other hand, the small one consisted mainly of cell component and collagen, possessing scarce myxoid stroma.
