Subarachnoid haemorrhage in children caused by cerebral tumour.

Subarachnoid haemorrhage in children is uncommon. In a review of 110 children with an intracranial tumour over a 20 year period there were four patients (3.6%) who presented with the typical features of a subarachnoid haemorrhage. During the same period of time there were 15 children who presented with subarachnoid haemorrhage of which 26% were secondary to a cerebral tumour. This study suggests that cerebral tumour is a common cause of subarachnoid haemorrhage in children.
