Overview

Intra-abdominal neuroblastoma must be differentiated from other diseases that cause abdominal distension and constipation such as Wilms tumor and ganglioneuroma. Intra-thoracic neuroblastoma must be differentiated from other diseases that cause shortness of breath and chronic cough such as intrathoracic lymphoma and extra lobar pulmonary sequestration.
