AbstractPediatric abusive head trauma (AHT) or non accidental head trauma (NAHT) is a major cause of death from trauma in children under 2 years of age. Main etiological factor for non accidental head trauma is shaking a baby, causing brain injury by rotational head acceleration and deceleration. The consequent brain damage as shown by magnetic resonance imaging (MRI) is subdural haemorrhage and to a lesser extent parenchymal injuries of variable severity. Involvement of the cerebellum has very rarely been described. We report the clinical history and the development of cerebral magnetic resonance imaging findings in two children with serious brain injury following probable shaking who presented the typical "triad" with subdural haematoma, retinal haemorrhage and encephalopathy. We want to draw attention to cerebellar involvement characterized by cortico-subcortical signal alterations most prominent on T2w images following diffusion changes during the acute period. We discuss cerebellar involvement as a sign of higher severity of AHT which is probably underrecognized.Copyright © 2019 European Paediatric Neurology Society. Published by Elsevier Ltd.
