Abstract
Acute cerebellitis is one of the main causes of acute cerebellar dysfunction in children. It is either infectious, usually viral, post-infectious or post vaccinal in etiology. Diagnosing acute cerebellitis may be difficult in patients with only subtle cerebellar signs and when cerebro-spinal fluid examination is normal. MRI is the most adequate imaging technique to demonstrate cerebellar involvement. The authors report the clinical and neuro-imaging findings in 4 paediatric cases. Patient's age varied from 2 to 7 years and predominant clinical symptoms were fever, headache and vomiting; ataxia was noted only in 2 cases. Viral serologic tests were negative in 3 cases and demonstrated Epstein-Barr virus in 1. Initial MRI examination (2 cases) demonstrated increased intensity on T2W and Flair sequences of the cerebellar gray matter with pial enhancement. Clinical outcome was good with complete resolution of symptoms in 3 cases and persistent mild right upper limb paresis in one. The resolution of the signal abnormality was well demonstrated on MRI in one case, suggesting an inflammatory etiology with moderate residual cerebellar atrophy.
