This is especially useful when tumours are bilateral. 22 (4): 911-34. The tumour morphology is often helpful, with the mass seen insinuating itself beneath the aorta and lifting it off the vertebral column. Neuroblastic tumors (ie, neuroblastoma, ganglioneuroblastoma, ganglioneuroma) are the most common extracranial solid tumors occurring in children ().The median age at diagnosis is about 16 months, and 95% of cases are diagnosed by 7 years of age (2,3).The most common sites of origin of neuroblastic tumors are the adrenal region (48%), extraadrenal … Patients with stage 1, 2, or 4S have a better prognosis.

Neuroblastoma | Radiology Reference Article | Radiopaedia.org The series is representative of the natural history of this disease prior to the use of actinomycin-D. No uniform method of treatment was employed. The treatments for Neuroblastoma and Wilms Tumor differs significantly, so the distinction between these tumor types prior to tumor exploration and resection is imperative. Radiographics. General imaging differential considerations include: 1. neuroblastoma: see neuroblastoma vs. Wilms tumor 2. cystic partially differentiated nephroblastoma and pediatric cystic nephroma: appear identical to very cystic Wilms tumor 1 3. clear cell sarcoma: generally indistinguishable on the bases of imaging, but may show early skeletal metastasis, a site which is unusual for Wilms tumor 4. renal rhabdoid tumor: generally, it can not be distinguished from Wilms on imaging, but the former has an established associa… It can present as an abdominal mass, but is usually metastatic at diagnosis so the symptomatology can be varied. Both neuroblastoma and Wilms tumor occur in early childhood and typically present as large abdominal masses closely related to the kidneys. Radiotherapy has a limited role, but may be employed in cases of peritoneal spread or incomplete resection 1. 11. Imaging of kidney cancer. The 1st Decade: From the Radiologic Pathology Archives.
