abstract="A 14-year-old boy and a 11-year-old boy presented with subdural hematomas as complications of preexisting arachnoid cysts in the middle cranial fossa, manifesting as symptoms of raised intracranial pressure. Both had a history of heading the ball in a soccer game about 7 weeks and 2 days before the symptom occurred. There was no other head trauma, so these cases could be described as &quot;heading injury.&quot; Arachnoid cysts in the middle cranial fossa are often associated with subdural hematomas. We emphasize that mild trauma such as heading of the ball in a soccer game may cause subdural hematomas in patients with arachnoid cysts.<p /><p>Language: en</p>",
