Traumatic basal subarachnoid haemorrhage (TBSAH) refers to a severe centred bleed, almost invariably resulting from micro-tear or in exceptional circumstances more lengthy dissection of the intracranial vertebrobasilar arterial system. This is typically caused by an impact side upper neck, angle jaw and/or ear/mastoid region. TBSAH associated with immediate comatose state, often accompanied int...

BACKGROUND Magnesium sulphate is a neuroprotective agent that might improve outcome after aneurysmal subarachnoid haemorrhage by reducing the occurrence or improving the outcome of delayed cerebral ischaemia. We did a trial to test whether magnesium therapy improves outcome after aneurysmal subarachnoid haemorrhage. METHODS We did this phase 3 randomised, placebo-controlled trial in eight cen...

A study of coroner's necropsy statistics showed that subarachnoid and cerebral haemorrhage were important causes of sudden death in the community. There were more sudden deaths due to cerebral haemorrhage in women than in men but this was due to the increasing frequency of this condition with age and the sexes were equally affected if standardized mortality rates were calculated. Comparison wit...

OBJECTIVES To measure the sensitivity and specificity of five MRI sequences to subarachnoid haemorrhage. METHODS Forty one patients presenting with histories suspicious of subarachnoid haemorrhage (SAH) were investigated with MRI using T1 weighted, T2 weighted, single shot fast spin echo (express), fluid attenuation inversion recovery (FLAIR), and gradient echo T2* sequences, and also by CT. ...

INTRODUCTION In this report we discuss an unusual cause of subarachnoid haemorrhage in association with neurofibromatosis. CASE PRESENTATION A previously fit 55-year-old man developed sudden onset headache with loss of consciousness. He was comatose on admission with no focal neurological signs. Numerous neurofibromas and café-au-lait patches were noted, indicating neurofibromatosis type 1 wh...
