Giant thoracoabdominal ganglioneuroblastoma in a 17-year-old patient.Asian Cardiovasc Thorac Ann 2014; 22(6):739-41AC
The most common malignant neurogenic tumors in children are neuroblastic tumors, classified as ganglioneuroblastoma or neuroblastoma. Ganglioneuroblastomas usually occur at the sympathetic ganglia in the mediastinum, whereas neuroblastomas occur in the abdominal cavity. We describe a case of large posterior mediastinal ganglioneuroblastoma extending from the aortic arch to the left renal hilum in a 17-year-old boy. Despite chemotherapy, post-treatment computed tomography showed disease progression. The patient underwent a thoracolaparotomy incision and excision of the tumor. These malignant mediastinal tumors can potentially grow to a very large size. If alternative treatment has failed, resection can be accomplished with relative safety.
