title: [Retroperitoneal ganglioneuroma: a case report].
abstract: A primary retroperitoneal ganglioneuroma was found incidentally in a 44-year-old man. Computed tomography revealed a homogeneous mass just above the right kidney. T1-weighted magnetic resonance imaging demonstrated the homogeneous mass, but T2-weighted imaging revealed a heterogeneous mass with a markedly high intensity area. The tumor was resected through a transabdominal approach. The resected specimen measured 11 x 9 x 4.5 cm and weighted 270 g. Histological examination showed that the lesion was a ganglioneuroma composed of mature ganglion cells and nerve fibers.
