Pelvic ganglioneuroblastoma totally excised using posterior sagittal and abdominal approach.

Neuroblastoma usually presents as an upper abdominal mass arising from the adrenal gland. Recent experience with neuroblastoma of the spermatic cord, bladder, and pelvis demonstrates the propensity of this tumor to arise in unusual areas. A 1-year-old boy was admitted with pollakiuria, acute urinary retention, and chronic constipation. Computed tomographic and ultrasonographic examinations revealed a 5×5.5×4-cm pelvic mass, which was totally excised using a posterior sagittal and abdominal approach. The pathologic diagnosis was ganglioneuroblastoma and 1-year follow-up was uneventful.
