We report a pediatric case of retroperitoneal ganglioneuroma that was successfully differentiated from an ovarian tumor using exploratory laparoscopy. The present case was an 8-year-old girl who was referred to our Department of Pediatrics with abdominal pain and an abdominal mass further evaluation because image screening by abdominal ultrasound and magnetic resonance imaging (MRI) revealed a 6-cm solid ovarian tumor. Based on these findings, we considered ovarian and retroperitoneal tumors as the differential diagnosis; however, the localization and assumed pathology of the tumor were not clear preoperatively. Due to persistent abdominal pain, examination of the intraperitoneal cavity was performed by exploratory laparoscopy. The uterus and bilateral adnexa were normal, and the tumor was located in the retroperitoneal cavity immediately through the peritoneum. The patient was transferred to the Department of Pediatric Surgery at the advanced pediatric medical center for surgery on the first postoperative day. The pathology of the resected tumor was ganglioneuroma. Since imaging modalities such as ultrasound and MRI are not always useful for localization and evaluations, the direct observation of abdominal masses by diagnostic laparoscopy in pediatric cases is necessary for accurate differentiation.}, pages = {15--21}, title = {診断的腹腔鏡手術により卵巣腫瘍と鑑別可能であった小児の後腹膜原発Ganglioneuromaの1例}, volume = {10}, year = {2021} }
