Serial Diffusion-Weighted and Conventional MR Imaging in Primary Cerebral Neuroblastoma Treated with Radiotherapy and Chemotherapy. A Case Report and Literature Review.

Primary cerebral neuroblastoma is a rare malignant tumor encountered most commonly in children. The radiological features of this entity are variable and rarely reported. The diffusion-weighted imaging (DWI) findings have not previously reported. We describe serial DWI and conventional MRI in a case of primary cerebral neuroblastoma to assess the imaging features and the role of DWI for monitoring chemoradiotherapy response.
