Subdural haemorrhage secondary to arachnoid cyst rupture from scuba diving

We describe a case of intracranial arachnoid cyst rupture leading to ipsilateral subacute subdural haemorrhage secondary to scuba diving in a previously healthy adult male. Our patient required urgent trephination of the cranium to evacuate the subdural haemorrhage and recovered well post operatively. To our knowledge this is the first case reported in the literature of arachnoid cyst rupture with concomitant subdural haemorrhage from scuba diving.  This case may have implications for information provided to patients with arachnoid cysts.
