Interestingly, patient 2 also had Crohn's disease, albeit not in active phase as demonstrated by instrumental investigations and blood test, thereby excluding Crohn's disease as possible cause of patient's symptoms. Computed tomography (CT) may be uninformative and magnetic resonance imaging (MRI) is necessary. CT may show cerebellar swelling and low density of the areas of the cerebellum involved, but these findings may be too subtle to identify, as in our patient 2. Typical MRI findings, if any, strongly support a diagnosis of acute cerebellitis in patients with compatible clinical presentation and cerebrospinal fluid (CSF) findings. [Extracted from the article]
