In this article diseases like Reye syndrome, Beh\u00e7et disease, pediatric neurosarcoidosis, Posterior Reversible Encephalopathy Syndrome are described. Some of the main neuroradiological differential aspects are also critically considered. Reye syndrome is characterized by symmetric thalamic, white matter and basal ganglia lesions, in children with recent history of salycilates or immunosuppressive drugs intake. The most typical MRI feature of neurosarcoidosis is basilar meningeal thickening and enhancement with intraparenchymal enhancing nodules and white matter focal abnormalities. The classical distribution of lesions helps differential diagnosis with infectious meningoencephalitis. Differential diagnosis with relapsing-remitting multiple sclerosis his helped by the evidence of meningeal abnormalities. Neuro-Beh\u00e7et is characterized by mesodiencephalic lesions in children with encephalopathy and coexistence of oral and genital ulcers and ocular abnormalities. PRES can be differentiated from vasculitis for the typical posterior white matter involvement and the different clinical features.<\/jats:p>","DOI":"10.1177\/197140091202500612","type":"journal-article","created":{"date-parts":[[2015,4,22]],"date-time":"2015-04-22T17:40:15Z","timestamp":1429724415000},"page":"725-738","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Pediatric Inflammatory Diseases"],"prefix":"10.1177","volume":"25","author":[{"given":"M.","family":"Gallucci","sequence":"first","affiliation":[{"name":"Chair and Unit of Neuroradiology, University of L'Aquila;
