Purpose: Neuroblastoma represents 8 to 10% of all pediatric tumors and account for 15% of cancer deaths in children. Neuroblastoma may arise anywhere sympathetic tissue is present and its clinical presentation may be very variable. Therefore, a significant number of unusual tumor presentation and imaging findings are possible.The purpose of this pictorial essay is to review the unusual imaging findings of neuroblastoma. Methods and materials: We retrospectively revised the 25 cases f neuroblastoma detected and treated at our institution in the last 3 years and selected those cases with atypical imaging findings at the initial diagnosis and the follow-up studies. Results: A significant number of our studies showed atypical imaging findings concerning the site of origin, the initial characteristics and extension of the primary tumor or the site of metastasis. Conclusion: The variability of origin and the changing clinical evolution of neuroblastoma may originate a wide spectrum of unusual imaging findings, which should be recognized to allow a correct diagnosis.
