title: The next extreme sport? Subdural haematoma in a patient with arachnoid cyst after head shaking competition.
abstract: A young man, engaged in a head shaking competition presented with headache, nausea and vomiting. Imaging revealed a subdural haematoma and ipsilateral arachnoid cyst. This novel mechanism of trauma underscores the predisposition to haemorrhage in patients with arachnoid cysts, even with minor trauma. Aetiology, imaging and possible treatment options are discussed.
