Neuroblastoma is the 3rd most common malignant tumor in infancy, following leukemia and CNS tumors. It is the second most common tumor encountered during childhood. Neuroblastoma is a malignant tumor originating from the neural crest. Patients are usually younger than 4 years of age. 46% of the cases are derived from the surrenal glands. But the tumor can be detected anywhere from the neck to the sacrum, wherever the sympathetic chain exists. 14% of the neuroblastomas originate within the thoracal region.
