Intracranial arachnoid cyst rupture after mild TBI in children: have we underestimated this risk?

The association between intracranial arachnoid cyst rupture and mild brain trauma is infrequently reported. The purpose of this case report is to describe the case of a child with a left temporal arachnoid cyst who suffered rupture with haemorrhage after mild trauma during a football match. The child presented with chronic headache of mild intensity that progressed to a more intense headache after a traumatic event.
