We studied a case of giant neurinoma of the intrapelvic retroperitoneum. The patient was a 60-year-old man who complained of dyschezia. Computed tomography and magnetic resonance imaging revealed a global mass occupying almost the entire pelvic cavity extraperitoneally. The tumor was diagnosed as a neurogenic pelvic tumor, and an operation was performed on January 17,1994. The tumor originated in the S2 nerve, so the proximal and distal S2 nerve were divided, and the tumor was excised. The excised specimen was 610 g in weight and 13.0 by 11.0 by 6.5 cm in size. Histopathological diagnosis was benign schwannoma of two different types, Antoni A and B, and was specifically identified as neurinoma at the intrepelvic retroperitoneum.
