title: Subarachnoid haemorrhage: difficulties in diagnosis and treatment.
abstract: Aneurysmal subarachnoid haemorrhage is associated with a uniquely severe headache of acute onset. Classical cases are readily identified as such, although this is not always the case. Four cases who were admitted to a district general hospital within a 3-month period are presented, because they demonstrate a variety of presentations, management options, and outcomes.
